Silvan Scherrer and Dmitry A. Kuminov have released the GA of the port of the
Qt 4 application framework to OS/2 and eComStation, i.e., version 4.5.1 GA. The
new release comes with complete support for drag and drop support, session
management, SQLite3, and includes Qt Designer application.
The GA includes the following changes in detail:
Improvements:
* general: Switched the compiler to the GCC 4.4.2 build provided by Paul
Smeldey. This gives better standard conformance, better code optimization and
provides more compact DLLs and EXEs whose size is greater than ~1M.
* corelib: QSettings: Use IniFormat (plain INI files) when NativeFormat is
requested instead of the Open32 registry which is known to be unstable and can
be easily corrupted. The old behavior may be restored using the QT_PM_REGISTRY
environment variable.
* corelib: Use UniStrcoll for QString::localeAwareCompare() for locale-aware
comparison of NLS strings.
* gui: Implemented full Direct Manipulation (Drag And Drop) support. This
includes dragging text, URLs and files between PM and Qt applications, dragging
any MIME data across Qt applications, setting custom drag pointer pixmaps,
painting in widgets while dragging.
* gui: Implemented session management with the QSessionManager class.
* gui: Fully implemented the QDesktopServices class.
* gui: Added support for numpad keys and for some common multimedia keys
recognized by eCS (volume, home, search, favorites).
* gui: QCursor: Added missing cursor shapes and implemented support for custom
cursor shapes.
* gui: Implemented QFontDatabase::addApplicationFont()/removeApplicationFont()
and friends.
* gui: Implemented proper generation of possible key and modifier combinations
for a given key event. This in particular enables Ctrl+ shortcuts for non-Latin
languages and also makes Ctrl+, Alt+ and similar shortcuts language-neutral.
* gui: QWidget: When setting the parent, take the parent's resolve masks to
make sure attributes imposed by the user on the parent won't be overriden by
the natural palette for this widget if it differs from QApplication::palette()
[vendor bug].
* gui: Use a normal border for top-level Tool widgets since the thin one is too
thin and cannot be resized.
* gui: Implemented delivering of QEvent::NonClientAreaMouse* events to
top-level widgets. This enables undocked dock widgets to be docked back by a
double click on the title bar and also by moving over the dock areas.
* plugins: Enabled the sqlite3 plugin which makes the sql module (and
applications depending on it) actually usable.
* tools: Enabled the Qt Designer application.
* tools: Enabled the following toos: pixeltool, q3toq4, xmplatterns.
* qmake/os2-g++: Recognize the "map" option in the CONFIG variable that allows
to turn the generation of .map files on and off. The option is set by default.
* qmake/os2-g++: Recognize the "highmem" option in the CONFIG variable that
allows to enabled memory support in LIBC for genereated DLLs and executables.
The option is set by default.
Fixes:
* corelib: Created wrappers for all Win* and Gpi* calls that restore the FPU
Control Word to what C/C++ programs expect. This fixes crashes in various Qt
applications (e.g. mp3diags) due to SIGFPE.
* corelib: QLibraryInfo: Fixed: qt.conf would not have been loaded if a
component path was requested before QCoreApplication instance creation.
* corelib: QLibraryInfo: Changed default "Settings" path to %ETC%/xdg. Also use
%ETC%/qtsys.conf as the system-wide qt.conf instead of %ETC%/qt/qtsys.conf.
* corelib: QFSFileEngine: Fixed: On OS/2, trailing spaces in file names are
ignored ("readme " = "readme") but kLIBC doesn't handle this well so strip them
before passing to LIBC APIs.
* corelib: QFile::copy(): Use DosCopy() instead of read/write.
* corelib: Fixed: QProcess::startDetached() would either crash or fail to start
a process.
* corelib: Fixed: QFileInfo::isExecutable() would return true for all files on
local OS/2 file systems.
* gui: Fixed: Popups shown when another application is active were not
controllable with keyboard and didn't close on an outside mouse click.
* gui: Fixed: Visible title bar and frame of the top-level window after
switching to fullscreen.
* gui: Fixed: Wrong widget-relative mouse position in mouse events. This fixes
problems with dragging widget splitters (separators) in applications using dock
widgets.
* gui: Fixed: QEvent::Enter/Leave events were delivered incorrectly if the
alien child widget belonging to a native parent intersected with a native child
of this parent (this in particular caused extended tool bars to immediately
un-extend once the mouse moves over the extended part).
* gui: Fixed: Mouse press events replayed after closing the popup by clicking
outside it had incorrect coordinates. This resulted into various kinds of
misbehavior including spatial text selection in QTextEdit widgets after closing
popups by clicking inside these widgets.
* gui: Fixed: The default application icon embedded into the executable was not
actually used as the default window icon for top-level widgets.
* qmake/os2-g++: Do not use EXEPACK tool on static libraries.
* qmake: Several fixes to make install targets work correctly.

Qt is a cross-platform application development framework, which is widely used
as a widget toolkit for developing GUI programs. Availability for OS/2 and
eComStation both means that developers can easily port existing Qt applications
and create new ones more easily.
This already has been the case with Qt 3. Now that Qt 4 is widely used, the
netlabs.org Qt 4 project aims to make the latest version available for OS/2 and
eComStation. After 4.5.1 GA has been released, updating to 4.6.1 will be worked
on if enough funds can be collected.

Since the project relies on funds made by the OS/2 and eComStation community,
