|
|
|
|
- The support for deployment on OS X 10.6 (Snow Leopard) is deprecated
|
|
in Qt 5.3, and will be removed in Qt 5.4. The platform is currently
|
|
not tested, and most likely has issues that are not fully documented.

QtWidgets
|
|
---------
|
|
|
|
QtCore
|
|
------
|
|
|
|
- Added QSignalBlocker, a RAII-style wrapper around
|
|
QObject::blockSignals().
|
|
|
|
QtGui

- Added setSwapInterval() to QSurfaceFormat. Platforms that support
|
|
setting the swap interval are now defaulting to the value of 1,
|
|
meaning vsync is enabled.

|
|
|
QtSql
|
|
-----
|
|
|
|
- QSqlQuery::isNull(field) now correctly returns true for "no such field".
|
|
- QSqlQuery::isNull(fieldname) is a new overload.
|
|
- QSQLITE: Empty database name now opens in-memory database.
|
|
- QSqlError: Now handles alphanumeric error codes. Used by QPSQL.
|
|
Old numeric code is deprecated.
