e3d32bce79 Fix failing qtdeclarativetextedit auto-test
After commit c3baa7c1dc the qtdeclarativetextedit
tests in the qtquick1 module started failing. This was due to commit
852abfca6f4c349dce9b895956922f96d82df579 from 4.8 not being forward-ported from
Qt 4 to Qt 5, hence the comment in c3baa7c1dc
about the missing mousePressEvent line. It was intentionally removed and
instead used further down, which is what this patch adds and therefore acts as
forward-port of 852abfca6f4c349dce9b895956922f96d82df579.

1a3d149174 qdoc: Revised logic for which example file to open in Qt Creator
qdoc stores the 'files to open' into the example manifest. These
files are opened in Qt Creator's editor when an example is selected
from the Welcome / Examples list.

This change uses the following criteria (case insensitive), in
order of preference:
    - .qml file matching the project name
    - .cpp file matching the project name
    - .h file matching the project name
    - main.qml
    - main.cpp

A 'mainFile = "true"' argument is written for the file that is
preferred to be the top-most file.

Having a main.qml file take precedence over main.cpp ensures that
most Qt Quick examples open into the relevant QML code instead of
the boilerplate C++ used for launching the application.

which does not return NSPanel subclasses, which is
used by Qt dialogs and pops.

Use [NSWidow windowNumberAtPoint:belowWindowWithWindowNumber]

can potentially include windows from other processes
and non-Qt windows which needs to be filtered out.

Add EXPECT_FAIL to tst_MacGui::nonModalOrder. The

this test is failing.

bc9423316f iOS: delay callbacks to UITextInput to avoid recursion
If the application calls "reset" or "commit" on the input
method (or forces active focus on some other item) from a text
changed or key pressed handler, iOS will sometimes throw
an exception. It does so because we try to change the state
of UITextInput (by calling textDidChange) while processing a
callback from the same place (insertText).

Optimally this should not happen since we would normally
post such events to Qt, not send them directly. But with
text input we cannot do this since UITextInput expects us
to update immediately upon receiving text input callbacks.
If not, word completion and spell checking will stop working.

This change will guard against recursive callbacks by delaying
callbacks to UITextInput when text/selection/first responder
changes.

Like the EGL + xcb configuration, the -no-opengl is broken too when
it comes to translucent windows: Requesting an alpha channel is futile

the doc/ dirs in the build dir won't be created until the docs have been

this also means that we'll get some complaints about non-existing

reasonable way to query qmake which repos are affected, and writing
shell-specific code to query it at make time seems a bit overengineered.

958a4c9087 QApp: Method to check for native style usage.
Adds QApplicationPrivate::usesNativeStyle to check whether the
QApplication is using the native platform style.

This can be needed internally to decided whether to let the platform
plugins do stuff or do it interally, style dependent. E.g. letting the
platform plugin popup a QMenu vs. letting the style draw one.

7df8b1ada4 Properly escape bytearray data outside the ascii range when using a codec
Some codecs can't handle the range outside ascii properly and would then
fail to read the data back in correctly.

91b0b2e1a7 Android: Repaint affected areas when window moves
There are no automatic updates of the window when it moves, since
this is not required on most platforms. This broke drag and drop on
Android, because drag and drop creates a temporary window containing
a pixmap with a snapshot of its content. We need to make sure the old
and new location of the window is repainted when it has moved.

[ChangeLog][Android] Fixed repaint issues in drag and drop.

90808ead98 Android: Fix flashing on startup/shutdown
There were several issues on startup of the application which
were caused by the fact that we would get the wrong
available screen geometry on startup, set this as the
initial surface size and then expose native windows with this
size. This would cause first a flicker of white on the early
expose and the window contents to jump around as the window was
resized to the actual available space on screen.

The fix for this is to postpone the first expose until we have
actually got a proper screen size from the main layout. We use
width,height = 0 as an indicator that the available geometry
is not yet known, and we skip posting any expose events before
this is set by the layout.

In addition, since we removed the surface before we shut down
the application, it was by a white rectangle before the
shutdown transition happens, and this white rectangle will
be animated instead of application contents.

To rectify this, we make sure the last surface in the stack
remains in the layout until it is either replaced by a different
surface or until the application has shut down. This way, the
shutdown animation will work on this surface instead.

[ChangeLog][Android] Fixed regression where there would be flickering
on startup and shutdown of the application.
