proprietary rights notice contained in any portion of the Licensed Software;
(ii) Applications must add primary and substantial functionality to the
Licensed Software;
(iii) Applications may not pass on functionality which in any way makes it
possible for others to create software with the Licensed Software; provided
however that Licensee may use the Licensed Software's scripting and QML ("Qt
Quick") functionality solely in order to enable scripting, themes and styles
that augment the functionality and appearance of the Application(s) without
adding primary and substantial functionality to the Application(s);
(iv) Applications must not compete with the Licensed Software;
(v) Licensee shall not use The Qt Company's or any of its suppliers' names,
logos, or trademarks to market Applications, except that Licensee may use

with, or use Licensed Software for creation of, any software created with or
incorporating Open Source Qt, or b) incorporate or integrate Applications
into a hardware device or product other than a Device, unless Licensee has
received an advance written permission from The Qt Company to do so. Absent
such written permission, any and all distribution by the Licensee during the
Term of a hardware device or product a) which incorporate or integrate any
part of Licensed Software or Open Source Qt; or b) where the main user
interface or substantial functionality is provided by software build with
Licensed Software or Open Source Qt or otherwise depends on the Licensed
Software or Open Source Qt, shall be considered as a Device distribution under
this Agreement and dependent on compliance thereof (including but not limited
to obligation to pay applicable License Fees for such distribution);
(ix) Licensee shall cause all of its Affiliates and Contractors entitled to
make use of the licenses granted under this Agreement, to be contractually
bound to comply with the relevant terms of this Agreement and not to use the
Licensed Software beyond the terms hereof and for any purposes other than

responsible for any and all actions and omissions of its Affiliates and
Contractors relating to the Licensed Software and use thereof (including but
not limited to payment of all applicable License Fees);
(x) Except when and to the extent explicitly provided in this Section 3,
Licensee shall not transfer, publish, disclose, display or otherwise make
available the Licensed Software;
; and
(xi) Licensee shall not attempt or enlist a third party to conduct or attempt
to conduct any of the above.
Above terms shall not be applicable if and to the extent they conflict with any
mandatory provisions of any applicable laws.
Any use of Licensed Software beyond the provisions of this Agreement is
strictly prohibited and requires an additional license from The Qt Company.
4. THIRD PARTY SOFTWARE
The Licensed Software may provide links to third party libraries or code
(collectively "Third Party Software") to implement various functions. Third
Party Software does not comprise part of the Licensed Software. In some cases,
access to Third Party Software may be included in the Licensed Software. Such
Third Party Software will be listed in the ".../src/3rdparty" source tree
delivered with the Licensed Software or documented in the Licensed Software, as
such may be amended from time to time. Licensee acknowledges that use or
distribution of Third Party Software is in all respects subject to applicable
license terms of applicable third party right holders.
5. PRE-RELEASE CODE
The Licensed Software may contain pre-release code and functionality marked or
otherwise stated as "Technology Preview", "Alpha", "Beta" or similar
designation. Such pre-release code may be present in order to provide
experimental support for new platforms or preliminary versions of one or more
new functionalities. The pre-release code may not be at the level of
performance and compatibility of a final, generally available, product
offering of the Licensed Software. The pre-release parts of the Licensed
Software may not operate correctly, may contain errors and may be substantially
modified by The Qt Company prior to the first commercial product release, if
any. The Qt Company is under no obligation to make pre-release code
commercially available, or provide any Support or Updates relating thereto. The
Qt Company assumes no liability whatsoever regarding any pre-release code, but
any use thereof is exclusively at Licensee's own risk and expense.
6. LIMITED WARRANTY AND WARRANTY DISCLAIMER
The Qt Company hereby represents and warrants that it has the power and
authority to grant the rights and licenses granted to Licensee under this
Agreement.
Except as set forth above, the Licensed Software is licensed to Licensee
"as is" and Licensee's exclusive remedy and The Qt Company's entire liability
for errors in the Licensed Software shall be limited, at The Qt Company's
option, to correction of the error, replacement of the Licensed Software or
return of the applicable fees paid for the defective Licensed Software for the
time period during which the License is not able to utilize the Licensed
Software under the terms of this Agreement.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE QT COMPANY ON BEHALF OF
ITSELF AND ITS LICENSORS, SUPPLIERS AND AFFILIATES, DISCLAIMS ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-
INFRINGEMENT WITH REGARD TO THE LICENSED SOFTWARE. THE QT COMPANY DOES NOT
WARRANT THAT THE LICENSED SOFTWARE WILL SATISFY LICENSEE'S REQUIREMENTS OR THAT
IT WILL OPERATE WITHOUT DEFECT OR ERROR OR THAT THE OPERATION THEREOF WILL BE
UNINTERRUPTED. ALL USE OF AND RELIANCE ON THE LICENSED SOFTWARE IS AT THE SOLE
RISK OF AND RESPONSIBILITY OF LICENSEE.
7. INDEMNIFICATION AND LIMITATION OF LIABILITY
7.1 Limitation of Liability
EXCEPT FOR (I) CASES OF GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT, AND (II)
BREACH OF CONFIDENTIALITY, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, IN NO
EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY LOSS OF PROFIT,
LOSS OF DATA, LOSS OF BUSINESS OR GOODWILL OR ANY OTHER INDIRECT, SPECIAL,
CONSEQUENTIAL, INCIDENTAL OR PUNITIVE COST, DAMAGES OR EXPENSE OF ANY KIND,
HOWSOEVER ARISING UNDER OR IN CONNECTION WITH THIS AGREEMENT. PARTIES
SPECIFICALLY AGREE THAT LICENSEE'S OBLIGATION TO PAY LICENSE AND OTHER FEES
CORRESPONDING TO ACTUAL USAGE OF LICENSED SOFTWARE HEREUNDER SHALL BE
CONSIDERED AS A DIRECT DAMAGE.
EXCEPT FOR (I) CASES OF GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT, AND (II)
BREACH OF CONFIDENTIALITY, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, IN
NO EVENT SHALL EITHER PARTY'S TOTAL AGGREGATE LIABILITY UNDER THIS AGREEMENT
EXCEED THE AGGREGATE LICENSE FEES PAID OR PAYABLE TO THE QT COMPANY FROM
LICENSEE DURING THE PERIOD OF TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE
EVENT RESULTING IN SUCH LIABILITY.
THE PROVISIONS OF THIS SECTION 7 ALLOCATE THE RISKS UNDER THIS AGREEMENT
BETWEEN THE QT COMPANY AND LICENSEE AND THE PARTIES HAVE RELIED UPON THE
LIMITATIONS SET FORTH HEREIN IN DETERMINING WHETHER TO ENTER INTO THIS AGREEMENT.
7.2 Licensee's Indemnification
Licensee shall indemnify and hold harmless The Qt Company from and against any
claim, injury, judgment, settlement, loss or expense, including attorneys' fees
related to: (a) Licensee's misrepresentation in connection with The Qt Company
or the Licensed Software or breach of this Agreement, (b) the Application or
Device (except where such cause of liability is solely attributable to the
Licensed Software).
8. SUPPORT, UPDATES AND ONLINE SERVICES
Upon due payment of the agreed License Fees the Licensee will be eligible to
receive Support and Updates and to use the Online Services during the License
Term, provided, however, that in the event the License Term is longer than 36
months, Support is provided only for the first 12 months, unless the Parties
specifically otherwise agree.
Unless otherwise decided by The Company at its free and absolute discretion,
Upgrades will not be included in the Support but may be available subject to
additional fees.
From time to time The Qt Company may change the Support terms, provided that
during the respective ongoing License Term the level of Support provided by The
Qt Company may not be reduced without the consent of the Licensee.
Unless otherwise agreed, The Qt Company shall not be responsible for providing
any service or support to Customers.
9. CONFIDENTIALITY
Each Party acknowledges that during the Term of this Agreement each Party may
receive information about the other Party's business, business methods,
business plans, customers, business relations, technology, and other
information, including the terms of this Agreement, that is confidential and
of great value to the other Party, and the value of which would be
significantly reduced if disclosed to third parties ("Confidential
Information"). Accordingly, when a Party (the "Receiving Party") receives
Confidential Information from the other Party (the "Disclosing Party"), the
Receiving Party shall only disclose such information to employees and
Contractors on a need to know basis, and shall cause its employees and
employees of its Affiliates to: (i) maintain any and all Confidential
Information in confidence; (ii) not disclose the Confidential Information to a
third party without the Disclosing Party's prior written approval; and (iii)
not, directly or indirectly, use the Confidential Information for any purpose
other than for exercising its rights and fulfilling its responsibilities
pursuant to this Agreement. Each Party shall take reasonable measures to
protect the Confidential Information of the other Party, which measures shall
not be less than the measures taken by such Party to protect its own
confidential and proprietary information.
Obligation of confidentiality shall not apply to information that (i) is or
becomes generally known to the public through no act or omission of the
Receiving Party; (ii) was in the Receiving Party's lawful possession prior to
the disclosure hereunder and was not subject to limitations on disclosure or
use; (iii) is developed independently by employees or Contractors of the
Receiving Party or other persons working for the Receiving Party who have not
had access to the Confidential Information of the Disclosing Party, as proven
by the written records of the Receiving Party; (iv) is lawfully disclosed to
the Receiving Party without restrictions, by a third party not under an
obligation of confidentiality; or (v) the Receiving Party is legally compelled
to disclose, in which case the Receiving Party shall notify the Disclosing
Party of such compelled disclosure and assert the privileged and confidential
nature of the information and cooperate fully with the Disclosing Party to
limit the scope of disclosure and the dissemination of disclosed Confidential
Information to the minimum extent necessary.
The obligations under this Section 9 shall continue to remain in force for a
period of five (5) years after the last disclosure, and, with respect to trade
secrets, for so long as such trade secrets are protected under applicable trade
secret laws.
10. FEES, DELIVERY AND PAYMENT
10.1 License Fees
License Fees are described in The Qt Company's standard price list, quote or
Purchase Order confirmation or in an appendix hereto, as the case may be.
The License Fees shall not be refunded or claimed as a credit in any event or
for any reason whatsoever.
10.2 Ordering Licenses
Licensee may purchase Development Licenses and Distribution Licenses pursuant
to agreed pricing terms or, if no specific pricing terms have been agreed upon,
at The Qt Company's standard pricing terms applicable at the time of purchase.
Licensee shall submit all purchase orders for Development Licenses and
Distribution Licenses to The Qt Company by email or any other method acceptable
to The Qt Company (each such order is referred to herein as a "Purchase Order")
for confirmation, whereupon the Purchase Order shall become binding between the
Parties.
10.3 Distribution License Packs
Unless otherwise agreed, Distribution Licenses shall be purchased by way of
Distribution License Packs.
Upon due payment of the ordered Distribution License Pack(s), the Licensee will
have an account of Distribution Licenses available for installing, bundling or
integrating (all jointly "installing") the Redistributables with the Devices or
for otherwise distributing the Redistributables in accordance with this
Agreement.
Each time Licensee "installs" or distributes a copy of Redistributables, then
one Distribution License is used, and Licensee's account of available
Distribution Licenses is decreased accordingly.
Licensee may "install" copies of the Redistributables so long as Licensee has
Distribution Licenses remaining on its account.
Redistributables will be deemed to have been "installed" into a Device when one
of the following circumstances shall have occurred: a) the Redistributables
have been loaded onto the Device and used outside of the Licensee's premises or
b) the Device has been fully tested and placed into Licensee's inventory
(or sold) for the first time (i.e., Licensee will not be required to use
(or pay for) more than one Distribution License for each individual Device,
e.g. in a situation where a Device is returned to Licensee's inventory after
delivery to a distributor or sale to a Customer). In addition, if Licensee
includes a back-up copy of the Redistributables on a CD-ROM or other storage
medium along with the product, that backup copy of the Redistributables will
not be deemed to have been "installed" and will not require an additional
Distribution License.
10.4 Payment Terms
License Fees and any other charges under this Agreement shall be paid by
Licensee no later than thirty (30) days from the date of the applicable invoice
from The Qt Company.
The Qt Company will submit an invoice to Licensee after the date of this
Agreement and/or after The Qt Company receives a Purchase Order from
Licensee.
A late payment charge of the lower of (a) one percent per month; or (b) the
interest rate stipulated by applicable law, shall be charged on any unpaid
balances that remain past due.
The Qt Company shall have the right to suspend, terminate or withhold grants
of all rights to the Licensed Software hereunder, including but not limited to
the Developer License, Distribution License, and Support, should Licensee fail
to make payment in timely fashion.
10.5 Taxes
All License Fees and other charges payable hereunder are gross amounts but
exclusive of any value added tax, use tax, sales tax and other taxes, duties or
tariffs ("Taxes"). Such applicable Taxes shall be paid by Licensee, or, where
applicable, in lieu of payment of such Taxes, Licensee shall provide an
exemption certificate to The Qt Company and any applicable authority.
11 RECORD-KEEPING AND REPORTING OBLIGATIONS; AUDIT RIGHTS
11.1 Licensee's Record-keeping
Licensee shall at all times maintain accurate and up-to-date written records of
Licensee's activities related to the use of Licensed Software and distribution
of Redistributables. The records shall be adequate to determine Licensee's
compliance with the provisions of this Agreement and to demonstrate the number
of Designated Users and Redistributables distributed by Licensee. The records
shall conform to good accounting practices reasonably acceptable to The Qt
Company.
Licensee shall, within thirty (30) days from receiving The Qt Company's request
to that effect, deliver to The Qt Company a report on Licensee's usage of
Licensed Software, such report to copies of Redistributables distributed by
Licensee during that calendar quarter, and also detailing the number of
undistributed copies of Redistributables made by Licensee and remaining in its
account contain information, in sufficient detail, on (i) amount of users
working with Licensed Software, (ii) copies of Redistributables distributed by
Licensee during that calendar quarter, (iii) number of undistributed copies of
Redistributables and corresponding number of unused Distribution Licenses
remaining on Licensee's account, and (iv) any other information as The Qt
Company may reasonably require from time to time.
11.2. The Qt Company's Audit Rights
The Qt Company or an independent auditor acting on behalf of The Qt Company's,
may, upon at least five (5) business days' prior written notice and at its
expense, audit Licensee with respect to the use of the Redistributables, but
not more frequently than once during each 6-month period. Such audit may be
conducted by mail, electronic means or through an in-person visit to Licensee's
place of business. Any such in-person audit shall be conducted during regular
business hours at Licensee's facilities and shall not unreasonably interfere
with Licensee's business activities. The Qt Company or the independent auditor
acting on behalf of The Qt Company shall be entitled to inspect Licensee's
Records. All such Licensee's Records and use thereof shall be subject to an
obligation of confidentiality under this Agreement.
If an audit reveals that Licensee is using the Licensed Software beyond scope
of the licenses Licensee has paid for, Licensee agrees to immediately pay The
Qt Company any amounts owed for such unauthorized use.
In addition, in the event the audit reveals a material violation of the terms
of this Agreement (underpayment of more than 5% of License Fees shall always be
deemed a material violation for purposes of this section), then the Licensee
shall pay The Qt Company's reasonable cost of conducting such audit.
12 TERM AND TERMINATION

This Agreement shall enter into force upon due acceptance by both Parties and
remain in force for as long as there is any Development License(s) in force
("Term"), unless and until terminated pursuant to the terms of this Section 12.
12.2 Termination by The Qt Company
The Qt Company shall have the right to terminate this Agreement upon thirty
(30) days prior written notice if the Licensee is in material breach of any
obligation of this Agreement and fails to remedy such breach within such notice
period.
12.3 Mutual Right to Terminate
Either Party shall have the right to terminate this Agreement immediately upon
written notice in the event that the other Party becomes insolvent, files for
any form of bankruptcy, makes any assignment for the benefit of creditors, has
a receiver, administrative receiver or officer appointed over the whole or a
substantial part of its assets, ceases to conduct business, or an act
equivalent to any of the above occurs under the laws of the jurisdiction of the
other Party.
12.4 Parties' Rights and Duties upon Termination
Upon expiry or termination of the Agreement Licensee shall cease and shall
cause all Designated Users (including those of its Affiliates' and
Contractors') to cease using the Licensed Software and distribution of the
Redistributables under this Agreement.
Notwithstanding the above, in the event the Agreement expires or is terminated:
(i) as a result of The Qt Company choosing not to renew the Development
License(s) as set forth in Section 3.1, then all valid licenses possessed by
the Licensee at such date shall be extended to be valid in perpetuity under the
terms of this Agreement and Licensee is entitled to purchase additional
licenses as set forth in Section 10.2; or
(ii) for reason other than by The Qt Company pursuant to item (i) above or
pursuant to Section 12.2, then the Licensee is entitled, for a period of six
(6) months after the effective date of termination, to continue distribution of
Devices under the Distribution Licenses paid but unused at such effective date
of termination.
Upon any such termination the Licensee shall destroy or return to The Qt
Company all copies of the Licensed Software and all related materials and will
certify the same to The Qt Company upon its request, provided however that
Licensee may retain and exploit such copies of the Licensed Software as it may
reasonably require in providing continued support to Customers.
Expiry or termination of this Agreement for any reason whatsoever shall not
relieve Licensee of its obligation to pay any License Fees accrued or payable
to The Qt Company prior to the effective date of termination, and Licensee
shall immediately pay to The Qt Company all such fees upon the effective date
of termination. Termination of this Agreement shall not affect any rights of
Customers to continue use of Applications and Devices (and therein incorporated
Redistributables).
12.5 Extension in case of bankruptcy
In the event The Qt Company is declared bankrupt under a final, non-cancellable
decision by relevant court of law, and this Agreement is not, at the date of
expiry of the Development License(s) pursuant to Section 3.1, assigned to
party, who has assumed The Qt Company's position as a legitimate licensor of
Licensed Software under this Agreement, then all valid licenses possessed by
the Licensee at such date of expiry, and which the Licensee has not notified
for expiry, shall be extended to be valid in perpetuity under the terms of
this Agreement.

Except in the case of a merger or sale of substantially all of its corporate
assets, Licensee shall not be entitled to assign or transfer all or any of its
rights, benefits and obligations under this Agreement without the prior written
consent of The Qt Company, which shall not be unreasonably withheld or delayed.
The Qt Company shall be entitled to freely assign or transfer any of its
rights, benefits or obligations under this Agreement.
14.2 No Third Party Representations

Software on behalf of The Qt Company. Any representation or warranty Licensee
makes or purports to make on The Qt Company's behalf shall be void as to The
Qt Company.
14.3 Surviving Sections
Any terms and conditions that by their nature or otherwise reasonably should
survive termination of this Agreement shall so be deemed to survive.
14.4 Entire Agreement
This Agreement, the exhibits hereto, the License Certificate and any applicable
Purchase Order constitute the complete agreement between the Parties and
supersedes all prior or contemporaneous discussions, representations, and
proposals, written or oral, with respect to the subject matters discussed
herein.
In the event of any conflict or inconsistency between this Agreement and any
Purchase Order, the terms of this Agreement will prevail over the terms of the
Purchase Order with respect to such conflict or inconsistency.
Parties specifically acknowledge and agree that this Agreement prevails over
any click-to-accept or similar agreements the Designated Users may need to
accept online upon download of the Licensed Software, as may be required by
The Qt Company's applicable processes relating to Licensed Software.
14.5 Modifications
No modification of this Agreement shall be effective unless contained in a
writing executed by an authorized representative of each Party. No term or
condition contained in Licensee's Purchase Order shall apply unless expressly
accepted by The Qt Company in writing.
14.6 Force Majeure
Except for the payment obligations hereunder, neither Party shall be liable to
the other for any delay or non-performance of its obligations hereunder in the
event and to the extent that such delay or non-performance is due to an event
of act of God, terrorist attack or other similar unforeseeable catastrophic
event that prevents either Party for fulfilling its obligations under this
Agreement and which such Party cannot avoid or circumvent ("Force Majeure
Event"). If the Force Majeure Event results in a delay or non-performance of a
Party for a period of three (3) months or longer, then either Party shall have
the right to terminate this Agreement with immediate effect without any
liability (except for the obligations of payment arising prior to the event of
Force Majeure) towards the other Party.

control restrictions under the applicable laws of respective countries.
Licensee shall fully comply with all applicable export license restrictions
and requirements as well as with all laws and regulations relating to the
Redistributables and exercise of licenses hereunder and shall procure all
necessary governmental authorizations, including without limitation, all
necessary licenses, approvals, permissions or consents, where necessary for the
re-exportation of the Redistributables, Applications and/or Devices.
14.9 No Implied License
There are no implied licenses or other implied rights granted under this
Agreement, and all rights, save for those expressly granted hereunder, shall
remain with The Qt Company and its licensors. In addition, no licenses or
immunities are granted to the combination of the Licensed Software with any
other software or hardware not delivered by The Qt Company under this Agreement.
14.10 Attorney Fees
The prevailing Party in any action to enforce this Agreement shall be entitled
to recover its attorney's fees and costs in connection with such action.

Qt 5.13.2 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 5.13.0 through 5.13.1.
For more details, refer to the online documentation included in this
distribution. The documentation is also available online:
https://doc.qt.io/qt-5/index.html
The Qt version 5.13 series is binary compatible with the 5.12.x series.
Applications compiled for 5.12 will continue to run with 5.13.
Some of the changes listed in this file include issue tracking numbers
corresponding to tasks in the Qt Bug Tracker:
https://bugreports.qt.io/
Each of these identifiers can be entered in the bug tracker to obtain more
information about a particular change.
****************************************************************************
* QtCore *
****************************************************************************
- Fixed a bug that made qErrnoWarning() say there was no error when
generating the error message.
- QBitArray:
* Fixed two bugs that caused QBitArrays created using fromBits() not to
compare equal to the equivalent QBitArray created using other methods
if the size was zero or not a multiple of 4. If the size modulus 8 was
5, 6, or 7, the data was actually incorrect.
- QCryptographicHash:
* Fixed a bug that caused the SHA-3 and Keccak algorithms to crash if
passed 256 MB of data or more.
- QObject:
* Fixed a resource leak caused by a race condition if multiple QObjects
were created at the same time, for the first time in an application,
from multiple threads (implies threads not started with QThread).
****************************************************************************
* QtGui *
****************************************************************************

****************************************************************************
* Important Behavioral Change *
****************************************************************************
- [QTBUG-47644] WrapWord now correctly prefers line breaks between words
in Korean text. WrapAnywhere can still be used to get breaks between
syllables instead.
****************************************************************************
* Potentially Source-Incompatible Changes *
****************************************************************************
- qstringlist.h no longer includes qregexp.h.
- Prefixing Q_NAMESPACE with an export macro may no longer work. Use the
new Q_NAMESPACE_EXPORT macro for that use case.
****************************************************************************
* QtCore *
****************************************************************************
- Added support of deduction guides for QPair
- Added new Qt::SplitBehavior, for use as eventual replacement for
QString::SplitBehavior.
- Added the new Q_NAMESPACE_EXPORT macro. It can be used just like
Q_NAMESPACE to add meta-object information to a namespace; however it
also supports exporting of such information from shared libraries.
- [QTBUG-15234] Qt installations on the host system can now be relocated,
i.e. moved to other directories.
- JSON:
* Added overloads of functions taking key strings as QStringView; in
QJsonObject, QJsonValue and QJsonDocument.
- QAtomicInteger:
* Added loadRelaxed() and storeRelaxed(), to be used as replacements of
load() / store().
- QAtomicPointer:
* Added loadRelaxed() and storeRelaxed(), to be used as replacements of
load() / store().
- QBasicTimer:
* QBasicTimer is now a move-only class. Copying is now deprecated and
will be removed in Qt 6.
* Added swap() member and free function.
- QByteArray::operator[]:
* Detach immediately, instead of deferring until modification via
the returned QByteRef.
* Deprecate reliance on its implicit resizing behavior. Support for
writing past the end of QByteArray shall be removed in a future
version of Qt.
- QCalendar:
* Added QCalendar to support diverse calendars, supported by
implementing QCalendarBackend.
* Added support for Julian and Milankovic calendars. These are enabled
by default, except in bootstrap builds.
* Added support for the Jalali (Persian or Solar Hijri) calendar,
controlled by feature jalalicalendar.
* Added support for the Islamic Civil calendar, controlled by feature
islamiccivilcalendar, with locale data that can be shared with other
implementations, controlled by feature hijricalendar.
- QChar:
* Added FormFeed (FF) special character.
- QCollator:
* Added support for QStringView.
* The default QCollator now uses the system's collation locale, rather
than the system locale itself.
- QDataStream:
* Enumerations can now be serialized through QDataStream without the
need of manually defining streaming operators.
- QDate:
* [QTBUG-64485] Added startOfDay() and endOfDay() methods to provide a
QDateTime at the start and end of a given date, taking account of any
time skipped by transitions, e.g. a DST spring-forward, which can lead
to a day starting at 01:00 or ending just before 23:00.
* Allow choice of calendar in various operations, with Gregorian
remaining the default.
- QDateTime:
* Invalid datetimes are now treated as equal and less than all valid
ones. They could previously be found equal to valid datetimes.
- QDir:
* Remove Windows specific long path markers when handling file paths
with native separators.
- QEasingCurve:
* QEasingCurve now properly streams all the data needed to QDataStream.
- QFileInfo:
* [QTBUG-75869] Introduced QFileInfo::isJunction() to detect NTFS Junctions
on Windows.
- QHash:
* Added range constructor.
- QJsonObject:
* Added insert(), remove(), and take() overloads taking QLatin1String.
- QLatin1Char:
* Comparison against char now works even in QT_NO_CAST_FROM_ASCII
builds.
- QLatin1Literal:
* The undocumented QLatin1Literal type alias for QLatin1String is now
deprecated. Use QLatin1String instead.
- QLatin1String:
* Added indexOf().
* Added contains().
* Added lastIndexOf().
- QLineF:
* added QLineF::intersects() as a replacement for QLineF::intersect()
- QLinkedList:
* Added range constructor.
- QList:
* Added range constructor.
- QLocale:
* The system locale now knows what to use for collation,
QLocale::system().collation().
* The NaN obtained when reading "nan" as a floating-point value is now
quiet rather than signaling.
* The system locale's UI languages list now includes, as for that of an
ordinary locale, the results of adding likely sub-tags from each
locale name, and of removing some, where this doesn't change which
locale is specified. This gives searches for translation files a
better chance of finding a suitable file.
- QMetaObject:
* [QTBUG-38876] Some internal members of the QMetaObject class have
changed types. Those members are not public API and thus should not
cause source incompatibilities.
- QMultiHash:
* Added range constructor.
- QMutex:
* Added QRecursiveMutex as a replacement of QMutex(QMutex::Recursive).
- QPoint/QPointF:
* Added transposed().
- QPointer:
* Added a free swap function.
- QSet:
* Added range constructor.
- QSharedPointer:
* Overloads of qSharedPointerObjectCast have been added to work on
std::shared_ptr.
* The swap overload for QSharedPointer in the std namespace has been
removed; a new overload has been added in the Qt namespace.
- QSize/QSizeF:
* Added grownBy(QMargin(F))/shrunkBy(QMargin(F)).
- QString:
* The behavior of operator[] to allow implicit resizing of the string
has been deprecated, and will be removed in a future version of Qt.
* QString::operator[] detaches immediately. Previously, the detach was
delayed until a modification was made to the string through the
returned QCharRef.
* QString::arg(QString, ..., QString) can now be called with more than
nine arguments, as well as with QStringViews.
- QString/QStringRef:
* The split functions now optionally take Qt::SplitBehavior.
- QStringList:
* Added range constructor.
* Added QStringView overloads of join(), filter(), and
replaceInStrings().
- QStringView:
* Added indexOf().
* Added contains().
* Added lastIndexOf().
* Deprecated the (undocumented) QStringViewLiteral macro. Just use u""
or QStringView(u"") instead.
- QStringView/QLatin1String:
* Added arg(), taking arbitrarily many strings.
- QTextStream:
* The NaN obtained when reading "nan" as a floating-point value is now
quiet rather than signaling.
- QTimeZone:
* [QTBUG-75565] The TZDB back-end now recognizes the contents of /etc/TZ
as a fall-back for $TZ (as used by uClibc).
- QVarLengthArray:
* Added range constructor.
* Added a qHash overload.
- QVariant:
* Fixed a bug that caused isNull() to be true after downcasting a
QObject* payload using convert().
- QVector:
* Added range constructor.
- QWeakPointer:
* The data() function has been deprecated.
* A swap overload has been added.
- QtGlobal:
* Add new macros QT_DEPRECATED_VERSION and QT_DEPRECATED_VERSION_X to
conditionally display deprecation warnings
* Added qExchange(), a drop-in for C++14's std::exchange()
- Windows:
* QSysInfo::prettyProductName() now returns a version including the
Windows 10 release id or Windows 7 build number respectively,
resembling the version string displayed by the winver tool.
****************************************************************************
* QtDBus *
****************************************************************************
- QDBusAbstractInterface:
* The call() and asyncCall() methods now accept more than eight QVariant
arguments.
- QDBusObjectPath:
* Added explicit cast operator to QVariant.
****************************************************************************
* QtGui *
****************************************************************************
- QColor:
* Added QColorConstants, a namespace containing constexpr QColor
instances.
- A QColorSpace class has been added, and color spaces are now parsed from
PNG and JPEG images. No automatic color space conversion is done
however, and applications must request it.
- Added support for filtering Vulkan debug messages in QVulkanInstance.
This is especially useful for processing or suppressing messages from
the validation layers.
- Obsolete constructors and accessors in QWheelEvent now have proper
deprecation macros, and are no longer in use in any Qt modules.
What is left is intended to be compatible with planned changes in Qt 6.
- QFont:
* [QTBUG-77908] Fixed kerning error with certain fonts.
* [QTBUG-76239] Fixed an issue where application fonts would be parsed
multiple times, causing some unnecessary overhead when during
application startup.
* [QTBUG-46322] Resolving a font that just has a family set with
families set will prepend the family to the families so that it is
still the first preference for the font.
- QImage:
* [QTBUG-42540], [QTBUG-68787] Loading of image files having a file
name suffix for a different image file type has been
fixed. QImageReader will now ask the suffix format handler to
confirm the file contents (canRead()), and fall back to normal
file content recognition on failure. This implies a slight
behavior change in QImageReader::loopCount(), ::imageCount() and
::nextImageDelay(): For an unreadable file with a recognized
suffix, they would earlier return 0, while they now will
return -1, i.e. error, as per the documentation.
- QPainter:
* HighQualityAntialiasing and NonCosmeticDefaultPen are marked as
deprecated and don't have an effect anymore
- QTextDocument:
* [QTBUG-36152] CSS styling of table cell borders (styling <td> and <th>
elements) is now supported during HTML import and export, including
border-color, border-width and border-style. Setting the table's
border-width to a value >= 1 and enabling border-collapse will now draw
a simple, clean table grid (1px) with an outer border of the specified
width and color. A manual test was added, which allows editing HTML
with live preview.
* [QTBUG-43589] Fixed incorrect rounding of widths of variable-width
columns in tables, to avoid border drawing artifacts.
* [QTBUG-78318] QTextFrameFormat margins, padding and borders are now
scaled to device coordinates, and thus correctly sized on high-dpi
displays and printers.
* Markdown (CommonMark or GitHub dialect) is now a supported format for
reading into and writing from QTextDocument, via the setMarkdown() and
toMarkdown() functions. We do not guarantee that every markdown
document can be re-written exactly as it was read; but that does work
in many cases, and it's OK to report bugs about cases that don't work.
- Touch:
* [QTBUG-77142] When a stationary touchpoint contains some "interesting"
property change (pressure or velocity, so far), it is delivered normally.
****************************************************************************
* QtNetwork *
****************************************************************************
- QAuthenticator:
* [QTBUG-4117] Add support for SPNEGO/Negotiate
- QHostInfo:
* Added move contructor.
- QNetworkAccessManager:
* [QTBUG-69477] Don't fail when FTP does not implement the HELP command.
* Added setAutoDeleteReplies to QNetworkAccessManager to enable the
AutoDeleteReplyOnFinishAttribute attribute for all QNetworkRequests
that are passed to QNetworkAccessManager.
- QNetworkRequest:
* Added the AutoDeleteReplyOnFinishAttribute attribute to
QNetworkRequest, which makes QNetworkAccessManager delete the
QNetworkReply after it has emitted the "finished" signal.
* Add an ability to configure HTTP/2 protocol
- QSslKey:
* Key data is cleared as soon as possible when move-assigning.
- QSslSocket:
* [QTBUG-72016] Added runtime validation of the SSL private key when it
is loaded through a file path.
****************************************************************************
* QtSql *
****************************************************************************
- QPSQL:
* [QTBUG-79033][QTBUG-79064] added support for PostgreSQL 12
- QSqlite:
* Updated to v3.30.1
- QSqlite2:
* Marked QSQLITE2 plugin as obsolete - it will be removed with Qt6
together with the QTDS plugin
****************************************************************************
* QtTestLib *
****************************************************************************
- Comparison of QImage, QPixmap now checks for the device pixel ratio.
- It is now possible to perform static initialization before QApplication
instantiation by implementing a initMain() function in the test class.
****************************************************************************
* QtWidgets *
****************************************************************************
- QActionGroup:
* Added new exclusionPolicy property. Set it to ExclusiveOptional to
allow unchecking the active checkable action in an exclusive group.
- QCalendarWidget:
* Allow choice of calendar, with Gregorian remaining the default.
- QComboBox:
* Two new signals textHighlighted() and textActivated() were added to
replace highlighted()/activated() QString overloads.
- QDateTimeEdit:
* Allow choice of calendar, with Gregorian remaining the default.
- QFileDialog:
* The widgets-based dialog now remembers the selected files when
navigating the history.
- QFormLayout:
* Honor the vertical expanding state of a widget inside a QFormLayout.
- QGraphicsWidget:
* Added QMarginsF overloads of setContentsMargins() and
setWindowFrameMargins().
- QGroupBox:
* [QTBUG-259389 Always disable children of a checkable, unchecked group
box before showing.
- QLabel:
* Markdown is now a supported textFormat for QLabel.
- QLayout:
* Prevent clipping of group box titles on macOS (and similar styles that
draw into layout margins)
- QLineEdit:
* Behavior change: now the editingFinished signal is emitted only once
after the line edit content was edited.
* The getTextMargins() member function has been deprecated in favor of
textMargins().
- QStyle:
* Style sheets now only use the part of the stylesheet font that it
knows about. The remaining will be resolved/inherited from the
context.
- QTextBrowser:
* Markdown is now a supported format. QTextBrowser::setSource() detects
the common file extensions (.md, .mkd and .markdown). In case it
cannot be detected that way, setSource() now takes an optional
ResourceType enum argument so that the type can be overridden.
QTextBrowser inherits all the QTextEdit features: if readOnly is set
to false, the user can perform the editing operations that QTextEdit
allows. If readOnly is set to true (the default), the user can click
Markdown hyperlinks to emit the anchorClicked() signal, as with HTML.
- QTextEdit:
* [QTBUG-75931] Added support for copy-pasting foreground brushes with
textures within same document.
* Markdown (CommonMark or GitHub dialect) is now a supported format,
via the markdown property. GitHub dialect is the default, and supports
all features such as hyperlinks, images, tables, lists, checklists, etc.
* If the text was loaded from a Markdown document that contains checkboxes,
the user can click on them to toggle the states. The cursor changes to
PointingHandCursor when the mouse is hovering over a checkbox.
- QTreeView:
* Don't emit clicked signal after a doubleClicked signal.
- QWidget:
* The getContentsMargins() member function has been deprecated in favor
of contentsMargins().
****************************************************************************
* Platform Specific Changes *
****************************************************************************
- Android
* Fixed an issue where an application installation would be irrecoverably
broken if power loss or a crash occurred during its first initialization
run.
* Make it easy to run Qt tests on Android. "$ make check" is all that's
needed to run a test on an Android device.
* Remove ant support from androiddeployqt
* Introduce "make apk" target, an easy way to create an apk.
* Android depends on NDK r20+
* Android multi arch build in one go, needed to support the new .aab
packaging format.
* -android-abis configure script parameter useful to compile Qt only for a
selected Android ABIs.
* Instead of bundling QML resources in assets and extracting them on first
start, Qt now creates an .rcc file and register it before invoking the
main function.
* Fixed regression that made it impossible for an application to use the
tap-and-hold gesture.
- Linux:
* Added a device spec for Raspberry Pi 4 (32-bit, V3D)
* Added a device spec for 64-bit i.MX8 systems (Vivante graphics stack)
- MinGW:
* [QTBUG-4155] Added a suffix to debug mode pkgconfig files.
- macOS:
* The drawableSize of Metal layers is no longer updated automatically on
window resize or screen change. Update the size manually in response to
resizeEvent(), or at the start of each frame, as needed.
- Mir:
* The Mir platform plugin has been removed: use the Wayland plugin when
connecting to a Mir display server.
- Windows:
* It is now possible to enable RTL mode by passing the option -platform
windows:reverse.
* [QTBUG-74748] Fixed a bug where it would be impossible to
request different faces of a font family after a specific type face
has been in use.
****************************************************************************
* Third-Party Code *
****************************************************************************
- Upgraded bundled Freetype version to 2.10.1.
- Build sqlite without SQLITE_OMIT_LOAD_EXTENSION
- Qt Gui: Added md4c markdown parser to src/3rdparty/md4c (MIT licensed).
- [QTBUG-79418] Updated double-conversion code to upstream version 3.1.5.
- [QTBUG-79420] libjpeg-turbo was updated to version 2.0.3
- [QTBUG-79418] Updated DNS public suffix list
****************************************************************************
* Tools *
****************************************************************************
- rcc:
* Added -d option to generate a dependency file.
* Added support for Python as output format.
****************************************************************************
* configure *
****************************************************************************
- Added the configure option -qtlibinfix-plugins to rename plugins
according to QT_LIBINFIX. This option is off by default.
****************************************************************************
* CMake *
****************************************************************************
- [QTBUG-38913][QTBUG-76562] Added ability to auto-import non-qml plugins
on CMake builds
****************************************************************************
* qmake *
****************************************************************************
- Installation targets do not ignore the exit code of QINSTALL and
QINSTALL_PROGRAM anymore.
- Introduced the variables LEX_DIR and YACC_DIR which determine the
location of lex/yacc output. Fixed parallel execution of lex/yacc for
debug_and_release builds.
- The syntax 'LIBS += -frameworkFoo', or 'LIBS += "-framework Foo"' is no
longer supported. Use the canonical 'LIBS += -framework Foo' instead.
- Fixed precompiled headers for the Clang compiler.
- Android:
* Remove gcc-style PCH directives from the android-clang mkspec.

****************************************************************************/
//! [displayName]
Returns a localized display name for the given location \a type
or an empty QString if no relevant location can be found.
//! [displayName]
//! [findExecutable]
Finds the executable named \a executableName in the specified
\a paths, or the system paths if paths is empty.
On most operating systems the system path is determined by the
\c PATH environment variable. The directories where to search for
the executable can be set in the paths argument. To search in
both your own paths and the system paths, call findExecutable
twice, once with paths set and once with paths empty.
Symlinks are not resolved in order to preserve behavior for the
case of executables whose behavior depends on the name they are
invoked with
.
\note On Windows, the usual executable extensions (from the PATHEXT
environment variable) are automatically appended. For example, the
findExecutable("foo") call finds \c foo.exe or \c foo.bat if
present.
Returns the absolute file path to the executable, or an empty
string if not found.
//! [findExecutable]
//! [locate]
Finds a file or directory called \a fileName in the standard
locations for \a type.
The \a options flag lets you specify whether to look for files
or directories. By default, this flag is set to \c LocateFile.
Returns the absolute path to the first file or directory found,
otherwise returns an empty string.
//! [locate]
//! [locateAll]
Finds all files or directories by the name, \a fileName, in the
standard locations for \a type.
The \a options flag lets you specify whether to look for files
or directories. By default, this flag is set to \c LocateFile.
Returns the list of all the files that were found.
//! [locateAll]
//! [setTestModeEnabled]
If \a testMode is \c true, this enables a special "test mode" in
QStandardPaths, which changes writable locations to point to
test directories. This prevents auto tests from reading
or writing to the current user's configuration.
It affects the locations into which test programs might write
files: \c GenericDataLocation, \c DataLocation, \c ConfigLocation,
\c GenericConfigLocation, \c AppConfigLocation,
\c GenericCacheLocation, and \c CacheLocation. Other locations
are not affected.
On Unix, \c XDG_DATA_HOME is set to \c{~/.qttest/share},
\c XDG_CONFIG_HOME is set to \c{~/.qttest/config}, and
\c XDG_CACHE_HOME is set to \c{~/.qttest/cache}.
On macOS, data goes to \c{~/.qttest/Application Support},
cache goes to \c{~/.qttest/Cache}, and config goes to
\c{~/.qttest/Preferences}.
On Windows, everything goes to a "qttest" directory under
\c{%APPDATA%}.
//! [setTestModeEnabled]
//! [standardLocations]
Returns all the directories where files of \a type belong.
The list of directories is sorted from high to low priority,
starting with writableLocation() if it can be determined.
This list is empty if no locations for type are defined.
//! [standardLocations]
//! [writableLocation]
Returns the directory where files of \a type should be written to,
or an empty string if the location cannot be determined.
\note The storage location returned may not exist; that is,
it may need to be created by the system or the user.
//! [writableLocation]

\title Porting Qt5 to Qt6 Guide
\brief Provides guidance to migrate your Qt 5 application to Qt 6.
Qt 6 is a result of the conscious effort to make this C++ framework more
efficient and easy to use. This release replaces quite a few legacy APIs with
more meaningful ones, such as the newer version of Qt Quick.
We try to maintain binary and source compatibility for all the public APIs in
each release, but some changes were inevitable in an effort to make Qt a
better framework. In this topic, we try to summarize those changes and
provide guidance to handle them.
The following list summarizes the changes in Qt 6:
\list
\li The major version number.

\brief The Shaped Clock example shows how to apply a translucent background
and a widget mask to a top-level widget to produce a shaped window.
\borderedimage shapedclock-example.png
Widget masks are used to customize the shapes of top-level widgets by restricting
the available area for painting. On some window systems, setting certain window flags
will cause the window decoration (title bar, window frame, buttons) to be disabled,
allowing specially-shaped windows to be created. In this example, we use this feature
to create a circular window containing an analog clock.
Widget masks are used to customize the shapes of top-level widgets by
restricting the area available for painting and mouse input. Using a
translucent background facilitates partially transparent windows and smooth

window decoration (title bar, window frame, buttons) to be disabled,
allowing specially-shaped windows to be created. In this example, we use
this feature to create a circular window containing an analog clock.
Since this example's window does not provide a \uicontrol File menu or a close
button, we provide a context menu with an \uicontrol Exit entry so that the example

The \c paintEvent() function is given for completeness. See the
\l{Analog Clock Example}{Analog Clock} example for a description of the process used
to render the clock.
The \c paintEvent() function is mainly the same as described in the
\l{Analog Clock Example}{Analog Clock} example. The one addition is that we
use QPainter::drawEllipse() to draw a round clock face with the current
palette's default background color. We make the clock face a bit smaller
than the widget mask, so that the anti-aliased, semi-transparent pixels on
the edge are not clipped away by the widget mask. This gives the shaped
window smooth edges on the screen.

\section1 Notes on Widget Masks
Widget masks are used to hint to the window system that the application
does not want mouse events for areas outside the mask. On most systems,
they also result in coarse visual clipping. To get smooth window edges, one
should use translucent background and anti-aliased painting, as shown in
this example.
Since QRegion allows arbitrarily complex regions to be created, widget masks can be
made to suit the most unconventionally-shaped windows, and even allow widgets to be
displayed with holes in them.
