8 | 4.6.3 (19-11-2010)
|
---|
9 |
|
---|
10 | Improvements:
|
---|
11 |
|
---|
12 | - general: Updated Qt codebase to version 4.6.3 (see the changes-4.6.3 file
|
---|
13 | for details). This version should be binary compatible with the previous
|
---|
14 | version of Qt for OS/2.
|
---|
15 |
|
---|
16 | - general: qmake uses .NOTPARALLEL for some targets to support parallel
|
---|
17 | building of complex applications with the -jN GNU make option.
|
---|
18 |
|
---|
19 | - corelib: Significantly improve the performance of directory iterators
|
---|
20 | walking through directories with thousands of files on slow file systems
|
---|
21 | with inefficient cache policies [based on patch by rudi].
|
---|
22 |
|
---|
23 | - corelib: Don't report non-existent floppy drives in QDir::drives(). This
|
---|
24 | makes letter A: and B: disappear from standard file dialogs in case if the
|
---|
25 | computer doesn't have the floppy controller at all or it is disabled in BIOS
|
---|
26 | [patch by rudi].
|
---|
27 |
|
---|
28 | - corelib: Implemented QSysInfo::os2Version(). Fixes the UserAgent string
|
---|
29 | in QWebKit-based browsers.
|
---|
30 |
|
---|
31 | - corelib: Fixed: Hang when attempting to stop the file watcher thread after
|
---|
32 | reusing it for more than one directory (e.g. like in the standard file
|
---|
33 | dialog).
|
---|
34 |
|
---|
35 | - network: Added OpenSSL support. This enables visiting web sites using the
|
---|
36 | secure HTTPS protocol in Qt based web-browser applications.
|
---|
37 |
|
---|
38 | - network: Improved network disk cache performance by reducing the number of
|
---|
39 | stat() calls twice when expiring the cache items [based on patch by rudi].
|
---|
40 |
|
---|
41 | - network: More verbose error messages from QLocalServer/QLocalSocket instead
|
---|
42 | of just "Unknown error".
|
---|
43 |
|
---|
44 | - network: QNetworkInterface::hardwareAddress() returns a real MAC and
|
---|
45 | netmask() returns a correct value.
|
---|
46 |
|
---|
47 | - plugins: Enabled the MySQL and PostgresSQL Qt plugins. Note that these
|
---|
48 | plugins require MySQL and PostgresSQL DLLs to be installed.
|
---|
49 |
|
---|
50 | - gui: DIVE: Detection code of the Panorama video driver now detects the
|
---|
51 | driver presence in memory rather than what will be loaded on next reboot.
|
---|
52 | This also solves redraw problems in cases where Panorama is installed
|
---|
53 | together with some other video extension -- the old method could not
|
---|
54 | detect Panorama and would enable DIVE leading to screen corruption.
|
---|
55 |
|
---|
56 | - gui: Send PDF data to a CUPS printer on by default if CUPS is version 1.4.4
|
---|
57 | or above (where printing PDF data was fixed).
|
---|
58 |
|
---|
59 | - gui: QCommonStyle::standardIconImplementation(): Generate the stanrad small
|
---|
60 | and/or large icon size if it is missing from the stock icon to avoid icon
|
---|
61 | size differences in e.g. file dialogs.
|
---|
62 |
|
---|
63 | - webkit: Try to allocate memory blocks in high memory on OS/2 first and fall
|
---|
64 | back to low memory on failure.
|
---|
65 |
|
---|
66 | Fixes:
|
---|
67 |
|
---|
68 | - general: Fixed: configure.cmd would not work in Object REXX bmode.
|
---|
69 |
|
---|
70 | - corelib: Fixed a deadlock during alien thread termination (copy-paste bug)
|
---|
71 | [found by komh].
|
---|
72 |
|
---|
73 | - corelib: Fixed: QProcess::startDetached() would fail with a certain set of
|
---|
74 | arguments [patch by rudi].
|
---|
75 |
|
---|
76 | - network: Fixed: QLocalServer/QLocalSocket: Make sure the socket path name
|
---|
77 | always starts with "\socket\". This fixes applications that use local
|
---|
78 | sockets for single application instance detection [based on patch by rudi].
|
---|
79 |
|
---|
80 | - network: Fixed: Filter out garbage entries returned by ioctl(SIOCGIFCONF) on
|
---|
81 | OS/2 so they don't appear in the QNetworkInteface::allInterfaces() list.
|
---|
82 |
|
---|
83 | - network: Fixed: QLocalServer could hang forever in the destructor trying to
|
---|
84 | close the listen socket being watched by a socket notifier. This fixes the
|
---|
85 | Assistant application hang at startup.
|
---|
86 |
|
---|
87 | - gui: Fixed: Doing Drag-n-Drop over a Qt target in DIVE mode would corrupt
|
---|
88 | the window contents.
|
---|
89 |
|
---|
90 | - gui: Fixed: Children with real HWNDs (a.k.a native widgets) were painted
|
---|
91 | over by the parent widget causing annoying flicker (smplayer).
|
---|
92 |
|
---|
93 | - gui: Fixed: In Dive mode, the screen would get corrupted if the application
|
---|
94 | created a child window with a real HWND (as e.g. smplayer does).
|
---|
95 |
|
---|
96 | - gui: Fixed: Qt Assistant would corrupt screen at startup in DIVE FB mode
|
---|
97 | [based on patch by rudi].
|
---|
98 |
|
---|
99 | - gui: Fixed: DIVE mode was unreasonably disabled in 24-bit color depth
|
---|
100 | display modes.
|
---|
101 |
|
---|
102 | - gui: Fixed: Path separator was missing in the output file name when printing
|
---|
103 | to a PDF or PS file in the print dialog.
|
---|
104 |
|
---|
105 | - gui: Fixed QFileDialog: Item height in the side bar was increased by
|
---|
106 | increasing icon size which caused ugly icon scaling. Now the item size hint
|
---|
107 | is used instead (based on the normal item height) [vendor bug].
|
---|
108 |
|
---|
109 | - gui: Fixed: Possible crash and an endless PM event loop recursion when
|
---|
110 | re-parenting widgets in DIVE mode. This could be seen when dragging a
|
---|
111 | toolbar out of the dock widget, dragging it back then closing the
|
---|
112 | application (crash) or attempting to drag the toolbar out again (endless
|
---|
113 | recursion).
|
---|
114 |
|
---|
115 | - gui: Fixed: Assertion shown when dragging the "Computer" item in the side
|
---|
116 | bar of the file dialog.
|
---|
117 |
|
---|
118 | - gui: Fixed: QCups would try to unlink() a NULL path which crashed some
|
---|
119 | libc implementations [vendor bug].
|
---|
120 |
|
---|
121 | - gui: Workaround: Set O_BINARY for temporary file descriptors we get from
|
---|
122 | CUPS when printing using the PDF engine to avoid file contents corruption.
|
---|
123 |
|
---|
124 | - gui: Fixed: Starting the drag operation would take the Qt focus away and
|
---|
125 | close all popups which is unexpected.
|
---|
126 |
|
---|
127 | - gui: Fixed: Repainting the widget during Drag-n-Drop outside the
|
---|
128 | drag*Event() callbacks would cause screen corruption under the mouse pointer
|
---|
129 | in DIVE mode.
|
---|
130 |
|
---|
131 | - gui: Fixed: Pressing Shift[+Ctrl]]+<numpad_digit> generated digits in
|
---|
132 | NumLock ON mode instead of cursor movement events (which is necessary to
|
---|
133 | make it possible to select text using numpad keys with Shift pressed.
|
---|
134 |
|
---|
135 | - gui: Fixed: Hiding the main application window programmatically with
|
---|
136 | QWidget::hide() and then showing it again with QWidget::show() would not
|
---|
137 | activate it from the Qt point of view which prevented the child widgets from
|
---|
138 | getting the keyboard focus (and input).
|
---|
139 |
|
---|
140 | - gui: Fixed a crash that could happen at program termination in DIVE mode if
|
---|
141 | a top-level window had a native HWND window embedded in it.
|
---|
142 |
|
---|
143 | - gui: Fixed SIGSEGV on SSE2 processors due to misaligned m128i variables
|
---|
144 | on stack (an OS/2-specific GCC 4.x compiler bug).
|
---|
145 |
|
---|
146 | - webkit: Fixed: Symbols typed with AltGr as a shift modifier could not be
|
---|
147 | entered in line entry fields in WebKit-based applications.
|
---|
148 |
|
---|
149 | - webkit: Fixed: posix_memalign() broken in kLIBC 0.6.3/4 whould crash in
|
---|
150 | QWebKit under heavy memory consumption conditions.
|
---|
151 |
|
---|
152 |
|
---|
153 | 4.6.2 (14-05-2010)
|
---|
154 |
|
---|
155 | Improvements:
|
---|
156 |
|
---|
157 | - general: Updated Qt codebase to version 4.6.2 (see the changes-4.6.2 file
|
---|
158 | for details). Note that this version is binary incompatible with the
|
---|
159 | previous version (see README.OS2 for more information).
|
---|
160 |
|
---|
161 | - general: Implemented support for the OS/2 platform in the webkit module. The
|
---|
162 | webkit module is used in many complex web-based applications such as web
|
---|
163 | browsers to implement the JavaScript support. Note that the script module
|
---|
164 | uses the JavaScript implementation from the WebKit project too and it was
|
---|
165 | also ported to OS/2. The webkit module is always present in the official Qt
|
---|
166 | build but is disabled by defautl in the custom builds due to big compilation
|
---|
167 | times.
|
---|
168 |
|
---|
169 | - general: Use declspec(dllexport) on OS/2 to significantly reduce the number
|
---|
170 | of exports in generated DLLs. This mode is on by default which reduces the
|
---|
171 | number of exported symbols by 90-100% in Qt DLLs and makes it not necessary
|
---|
172 | to split the QtGui DLL in 3 parts in debug mode. The old method which causes
|
---|
173 | all public symbols to be exported is still available using the "export_all"
|
---|
174 | CONFIG option (see README.OS2 for details).
|
---|
175 |
|
---|
176 | - general: Provide the "doc" WPI archive that contains the Qt reference
|
---|
177 | documentation.
|
---|
178 |
|
---|
179 | - corelib: Implemented native (XWP-based) file system watcher for OS/2 that
|
---|
180 | does not eat CPU (which is best noticed in file dialogs showing directories
|
---|
181 | containing hundreds of files. Requires XWorkplace to be installed.
|
---|
182 |
|
---|
183 | - corelib: Implemented deriving the defaut locale from the process country
|
---|
184 | code if LANG is not set and integration with the system locale object
|
---|
185 | (System Setup -> Country Palette). See the QT_PM_NO_SYSTEM_LOCALE
|
---|
186 | description in README.OS2 for details.
|
---|
187 |
|
---|
188 | - gui: Implemented printing support through CUPS. Refer to section "PRINTING
|
---|
189 | SUPPORT" in README.OS2 for details.
|
---|
190 |
|
---|
191 | - gui: Implemented painting in widgets using DIVE (direct interface video
|
---|
192 | extensions). Using DIVE gives a significant graphical performance boost, up
|
---|
193 | to 100% in BLIT mode and 130% in FBSWM mode, depending on the combination of
|
---|
194 | the graphics hardware, video driver and the current screen mode. See the
|
---|
195 | QT_PM_DIVE and QT_PM_NO_DIVE description in README.OS2 for more details.
|
---|
196 |
|
---|
197 | - gui: Improved the painting speed when not using DIVE. The performance boost
|
---|
198 | varies from 30% to 200% (e.g. 3 times faster), depending on the combination
|
---|
199 | of the graphics hardware, video driver and the current screen mode.
|
---|
200 |
|
---|
201 | - gui: Enabled MMX/SSE support (on by default) to speed up graphical
|
---|
202 | operations by a couple of percents.
|
---|
203 |
|
---|
204 | - gui: Enabled accessibility support on OS/2. Note that in order to use the
|
---|
205 | accessibility functions, a QAccessibleBridge plugin for the corresponding
|
---|
206 | accessibility device is necessary but none of them exist at the present
|
---|
207 | time.
|
---|
208 |
|
---|
209 | - gui: Use native file icons in standard Qt file dialogs.
|
---|
210 |
|
---|
211 | - assistant: Enabled the help module and made the Qt Assistant tool build on
|
---|
212 | OS/2. Also enabled help and assistant examples and demos.
|
---|
213 |
|
---|
214 | - demos: Enabled the browser demo application that makes use of the webkit
|
---|
215 | module.
|
---|
216 |
|
---|
217 | - demos: Enabled the qtdemo example that demonstrates all Qt features and
|
---|
218 | acts as a launcher for other example and demo applications.
|
---|
219 |
|
---|
220 | - gnumake/os2-g++: Switch the compiler to using the i486 instruciton set for
|
---|
221 | code generation. This gives around 3% of the performance boost when
|
---|
222 | painting. As a drawback, the code will no longer run on i386 PCs but it is
|
---|
223 | assumed that it does not make sense to use Qt4 on these computers.
|
---|
224 |
|
---|
225 | Fixes:
|
---|
226 |
|
---|
227 | - general: Fixed: Building Qt applications with the "dev" WPI archive would
|
---|
228 | fail due to extra spaces in the output object file names.
|
---|
229 |
|
---|
230 | - corelib: Fixed: Regular files were treated as sequential streams which made
|
---|
231 | the seek functionality unavailable. This in particular affected Qt Designer
|
---|
232 | that didn't expect sequential streams when reading .ui files and refused to
|
---|
233 | load files bigger than 8192 bytes as a result.
|
---|
234 |
|
---|
235 | - corelib: Make sure the hardware error popup dialogs do not appear when
|
---|
236 | opening the standard Qt file dialog and selecting a removable drive with no
|
---|
237 | media inserted even with AUTOFAIL=YES in CONFIG.SYS
|
---|
238 |
|
---|
239 | - corelib: QProcess: Fixed: Data could not be successfully read or written to
|
---|
240 | the standard streams of the started process in 'highmem' link mode (which is
|
---|
241 | on by default since 4.5.1 GA), as well as in normal link mode in some
|
---|
242 | situations.
|
---|
243 |
|
---|
244 | - corelib: Fixed QProcess::startDetached() which would not work in 'highmem'
|
---|
245 | mode.
|
---|
246 |
|
---|
247 | - corelib: QProcess: Fixed: Having stderr of a started child process
|
---|
248 | redirected to a pipe (which is the default) would indirectly cause an
|
---|
249 | impossibility to write anything to its stdin.
|
---|
250 |
|
---|
251 | - corelib: QProcess: Get rid of the unexpected "DosQueryNPipeSemState returned
|
---|
252 | 87" warning.
|
---|
253 |
|
---|
254 | - corelib: QFileSystemWatcher: In the fall-back polling watcher, increased the
|
---|
255 | sleep time between checks of all watched files from 1 second to 3 seconds to
|
---|
256 | decrease the CPU load on big sets of watched files. Also, replaced the sleep
|
---|
257 | between checking individual items with the yield call as it doesn't give
|
---|
258 | significant improvement but just causes more CPU cycles to be spent between
|
---|
259 | each check.
|
---|
260 |
|
---|
261 | - corelib: Always return true from QFileInfo::isRoot()/isDir() for paths
|
---|
262 | referring to root directories of drives with no media and always return
|
---|
263 | false from QFileInfo::exists() for them. Also, don't lstat() on such paths
|
---|
264 | since they are definitely not symlinks. This improves the file dialog
|
---|
265 | appearance and behavior for removable drives.
|
---|
266 |
|
---|
267 | - corelib: Protect against the frozen system when QSocketNotifier is given an
|
---|
268 | unsupported socket (for example, an OS/2 file handle). There is still 100%
|
---|
269 | CPU load in this case, but the application can be at least closed using
|
---|
270 | normal means.
|
---|
271 |
|
---|
272 | - corelib: Sockets: Fixed: "has data to read" socket notifications would be
|
---|
273 | sometimes delivered with a delay depending on the frequency of timers which
|
---|
274 | could significantly slow down network data transfer.
|
---|
275 |
|
---|
276 | - corelib: QTemporaryFile: Fixed: Files were opened in O_TEXT mode which
|
---|
277 | caused unexpected LF <-> CRLF translation. In particular, this broke
|
---|
278 | QNetworkDiskCache functionality (seen in e.g. demos/browser as missing
|
---|
279 | images and CSS sheets when read from cache).
|
---|
280 |
|
---|
281 | - corelib: Fixed: Clear FPU CW in qdtoa() to avoid the floating point
|
---|
282 | exception in various scenarios [patch by rudi].
|
---|
283 |
|
---|
284 | - gui: Fixed assertion in QVector::at() at startup.
|
---|
285 |
|
---|
286 | - gui: Fixed assertion at #1125 in qwidget.cpp (due to an attempt to
|
---|
287 | re-instantiate QDesktopWidget during application termination).
|
---|
288 |
|
---|
289 | - gui: Select the correct icon for the drive letter in standard file dialogs
|
---|
290 | depending on the drive type (floppy, hard disk etc) [patch by rudi].
|
---|
291 |
|
---|
292 | - gui: Fixed crash in PMMERGE during resize & move of the top level window
|
---|
293 | with the complex layout (caused by reading outside the bitmap data).
|
---|
294 |
|
---|
295 | - gui: Fixed: Never add tooltip windows to the top-level window list and only
|
---|
296 | do so for splash windows if they have the Qt::WindowTitleHint flag set.
|
---|
297 |
|
---|
298 | - 3rdparty: Added OS/2 support to clucene used by the help module for fulltext
|
---|
299 | search in help files [based on the patch by rudi].
|
---|
300 |
|
---|
301 | - configure.cmd: Fixed: QT_BUILD_KEY (and QLibraryInfo::buildKey()) would
|
---|
302 | always contain "release", even in debug builds, which caused debug builds to
|
---|
303 | load the release plugins and refuse the debug ones.
|
---|
304 |
|
---|
305 | - qmake/os2-g++: Use -Wl, to pass the object list response file to the
|
---|
306 | linker as is instead of the expanded list of objects (this overcomes the
|
---|
307 | 64KB limitation of the total process command line length in OS/2).
|
---|
308 |
|
---|
309 |
|
---|
310 | 4.5.1 GA (05-02-2010)
|
---|
311 |
|
---|
312 | Improvements:
|
---|
313 |
|
---|
314 | - general: Switched the compiler to the GCC 4.4.2 build provided by Paul
|
---|
315 | Smeldey. This gives better standard conformance, better code optimization
|
---|
316 | and provides more compact DLLs and EXEs whose size is greater than ~1M.
|
---|
317 |
|
---|
318 | - corelib: QSettings: Use IniFormat (plain INI files) when NativeFormat is
|
---|
319 | requested instead of the Open32 registry which is known to be unstable and
|
---|
320 | can be easily corrupted. The old behavior may be restored using the
|
---|
321 | QT_PM_REGISTRY environment variable.
|
---|
322 |
|
---|
323 | - corelib: Use UniStrcoll for QString::localeAwareCompare() for locale-aware
|
---|
324 | comparison of NLS strings.
|
---|
325 |
|
---|
326 | - gui: Implemented full Direct Manipulation (Drag And Drop) support. This
|
---|
327 | includes dragging text, URLs and files between PM and Qt applications,
|
---|
328 | dragging any MIME data across Qt applications, setting custom drag pointer
|
---|
329 | pixmaps, painting in widgets while dragging.
|
---|
330 |
|
---|
331 | - gui: Implemented session management with the QSessionManager class.
|
---|
332 |
|
---|
333 | - gui: Fully implemented the QDesktopServices class.
|
---|
334 |
|
---|
335 | - gui: Added support for numpad keys and for some common multimedia keys
|
---|
336 | recognized by eCS (volume, home, search, favorites).
|
---|
337 |
|
---|
338 | - gui: QCursor: Added missing cursor shapes and implemented support for custom
|
---|
339 | cursor shapes.
|
---|
340 |
|
---|
341 | - gui: Implemented QFontDatabase::addApplicationFont()/removeApplicationFont()
|
---|
342 | and friends.
|
---|
343 |
|
---|
344 | - gui: Implemented proper generation of possible key and modifier combinations
|
---|
345 | for a given key event. This in particular enables Ctrl+<letter> shortcuts
|
---|
346 | for non-Latin languages and also makes Ctrl+<letter>, Alt+<letter> and
|
---|
347 | similar shortcuts language-neutral.
|
---|
348 |
|
---|
349 | - gui: QWidget: When setting the parent, take the parent's resolve masks to
|
---|
350 | make sure attributes imposed by the user on the parent won't be overriden
|
---|
351 | byv the natural palette for this widget if it differs from
|
---|
352 | QApplication::palette() [vendor bug].
|
---|
353 |
|
---|
354 | - gui: Use a normal border for top-level Tool widgets since the thin one is
|
---|
355 | too thin and cannot be resized.
|
---|
356 |
|
---|
357 | - gui: Implemented delivering of QEvent::NonClientAreaMouse* events to
|
---|
358 | top-level widgets. This enables undocked dock widgets to be docked back by
|
---|
359 | a double click on the title bar and also by moving over the dock areas.
|
---|
360 |
|
---|
361 | - plugins: Enabled the sqlite3 plugin which makes the sql module (and
|
---|
362 | applications depending on it) actually usable.
|
---|
363 |
|
---|
364 | - tools: Enabled the Qt Designer application.
|
---|
365 |
|
---|
366 | - tools: Enabled the following toos: pixeltool, q3toq4, xmplatterns.
|
---|
367 |
|
---|
368 | - qmake/os2-g++: Recognize the "map" option in the CONFIG variable that allows
|
---|
369 | to turn the generation of .map files on and off. The option is set by
|
---|
370 | default.
|
---|
371 |
|
---|
372 | - qmake/os2-g++: Recognize the "highmem" option in the CONFIG variable that
|
---|
373 | allows to enabled memory support in LIBC for genereated DLLs and
|
---|
374 | executables. The option is set by default.
|
---|
375 |
|
---|
376 | Fixes:
|
---|
377 |
|
---|
378 | - corelib: Created wrappers for all Win* and Gpi* calls that restore the FPU
|
---|
379 | Control Word to what C/C++ programs expect. This fixes crashes in various
|
---|
380 | Qt applications (e.g. mp3diags) due to SIGFPE.
|
---|
381 |
|
---|
382 | - corelib: QLibraryInfo: Fixed: qt.conf would not have been loaded if a
|
---|
383 | component path was requested before QCoreApplication instance creation.
|
---|
384 |
|
---|
385 | - corelib: QLibraryInfo: Changed default "Settings" path to %ETC%/xdg.
|
---|
386 | Also use %ETC%/qtsys.conf as the system-wide qt.conf instead of
|
---|
387 | %ETC%/qt/qtsys.conf.
|
---|
388 |
|
---|
389 | - corelib: QFSFileEngine: Fixed: On OS/2, trailing spaces in file names are
|
---|
390 | ignored ("readme " = "readme") but kLIBC doesn't handle this well so strip
|
---|
391 | them before passing to LIBC APIs.
|
---|
392 |
|
---|
393 | - corelib: QFile::copy(): Use DosCopy() instead of read/write.
|
---|
394 |
|
---|
395 | - corelib: Fixed: QProcess::startDetached() would either crash or fail to
|
---|
396 | start a process.
|
---|
397 |
|
---|
398 | - corelib: Fixed: QFileInfo::isExecutable() would return true for all files on
|
---|
399 | local OS/2 file systems.
|
---|
400 |
|
---|
401 | - gui: Fixed: Popups shown when another application is active were not
|
---|
402 | controllable with keyboard and didn't close on an outside mouse click.
|
---|
403 |
|
---|
404 | - gui: Fixed: Visible title bar and frame of the top-level window after
|
---|
405 | switching to fullscreen.
|
---|
406 |
|
---|
407 | - gui: Fixed: Wrong widget-relative mouse position in mouse events. This fixes
|
---|
408 | problems with dragging widget splitters (separators) in applications using
|
---|
409 | dock widgets.
|
---|
410 |
|
---|
411 | - gui: Fixed: QEvent::Enter/Leave events were delivered incorrectly if the
|
---|
412 | alien child widget belonging to a native parent intersected with a native
|
---|
413 | child of this parent (this in particular caused extended tool bars to
|
---|
414 | immediately un-extend once the mouse moves over the extended part).
|
---|
415 |
|
---|
416 | - gui: Fixed: Mouse press events replayed after closing the popup by clicking
|
---|
417 | outside it had incorrect coordinates. This resulted into various kinds of
|
---|
418 | misbehavior including spatial text selection in QTextEdit widgets after
|
---|
419 | closing popups by clicking inside these widgets.
|
---|
420 |
|
---|
421 | - gui: Fixed: The default application icon embedded into the executable was
|
---|
422 | not actually used as the default window icon for top-level widgets.
|
---|
423 |
|
---|
424 | - qmake/os2-g++: Do not use EXEPACK tool on static libraries.
|
---|
425 |
|
---|
426 | - qmake: Several fixes to make install targets work correctly.
|
---|
427 |
|
---|
428 |
|
---|
429 | Beta 5 (06-12-2009)
|
---|
430 |
|
---|
431 | Improvements:
|
---|
432 |
|
---|
433 | - gui: Added support for the system clipboard. Qt can now exchange plain text,
|
---|
434 | HTML (Mozilla application suite) and bitmaps with other PM applications, as
|
---|
435 | well as all supported MIME data types with other Qt-based applications.
|
---|
436 |
|
---|
437 | - corelib: Use system unicode conversion routines to convert from the system
|
---|
438 | code page to Unicode and back. This makes it unnecessary to specify the
|
---|
439 | system encoding in the LANG environment variable -- Qt will use the system
|
---|
440 | encoding of the current process.
|
---|
441 |
|
---|
442 | - gui: Implemented support for the IME input box (used on DBCS systems) in Qt
|
---|
443 | applications with a known limitation that the input box is always positioned
|
---|
444 | at the lower left corner of the top-level window.
|
---|
445 |
|
---|
446 | - gui: Improved font handling on DBCS systems (patch by komh):
|
---|
447 | * Read national face names from font files instead of always taking the
|
---|
448 | Latin name.
|
---|
449 | * Use the PM_AssociateFont registry key to select a fallback font for
|
---|
450 | missing characters.
|
---|
451 |
|
---|
452 | - gui: Implemented QPixmap::grabWindow() which takes a screenshot of a window.
|
---|
453 |
|
---|
454 | - gui: Steal the Alt key from the PM which prevents the PM system menu to be
|
---|
455 | shown when single Alt is pressed in a Qt application. The system menu may
|
---|
456 | still be called using Alt+Space. Note that this also disables all default
|
---|
457 | shortuts from the system menu (Alt+F7, Alt+F10 etc.) so that they available
|
---|
458 | to Qt applications now. Exceptions are Alt+F4, Ctrl+Esc, Alt+Esc which are
|
---|
459 | not passed to Qt and will function as in regular PM applciations.
|
---|
460 |
|
---|
461 | - general: Binary Qt library builds are made portable: they do not contain
|
---|
462 | hard-coded paths to various Qt components any more and use relative
|
---|
463 | locations whenever possible. See
|
---|
464 | http://svn.netlabs.org/qt4/browser/tags/4.5.1-os2-beta5/doc/src/qt-conf.qdoc
|
---|
465 | for more info.
|
---|
466 |
|
---|
467 | - corelib: Improved the polling QFileSystemWatcher implementation so that it
|
---|
468 | doesn't eat all CPU when there are more than 100 items to watch, like when
|
---|
469 | showing a file open dialog with many files in a directory.
|
---|
470 |
|
---|
471 | - qmake: Improved processing of the project library list (LIBS variable) to
|
---|
472 | avoid appearance of raw library names that require substitution (fixes the
|
---|
473 | debug build of linguist).
|
---|
474 |
|
---|
475 | - qmake: Added support for DEF_FILE_VERSION, DEF_FILE_DESCRIPTION and
|
---|
476 | DEF_FILE_VENDOR project variables that allow to embed the description
|
---|
477 | string into a generated DLL or executable. For compatibility with other
|
---|
478 | platforms, these variables by default are mapped to VERSION,
|
---|
479 | QMAKE_TARGET_PRODUCT + QMAKE_TARGET_DESCRIPTION + QMAKE_TARGET_COPYRIGHT and
|
---|
480 | QMAKE_TARGET_COMPANY, respectively.
|
---|
481 |
|
---|
482 | Fixes:
|
---|
483 |
|
---|
484 | - gui: Table views showed alternate rows in black color instead of light gray.
|
---|
485 |
|
---|
486 | - gui: If some font style (e.g. Bold) does not provide characters for some
|
---|
487 | script (e.g. Cyrillic) while the Normal style does, a different font will be
|
---|
488 | chosen for Bold Cyrillic instead of drawing empty boxes.
|
---|
489 |
|
---|
490 | - corelib: Fixed two issues related to loading text codec plugins from the
|
---|
491 | application's directory.
|
---|
492 |
|
---|
493 | - corelib: Fixed QDir::absoluteFilePath(), midir()/mkpath(), rmdir()/rmpath()
|
---|
494 | that didn't properly handle relative and UNC paths which could cause various
|
---|
495 | path-related failures.
|
---|
496 |
|
---|
497 | - corelib: Properly report root directories of drives to Qt. This makes
|
---|
498 | letters of removable drives always seen by Qt (for example, in the file open
|
---|
499 | dialog) even if the medium isn't currently inserted.
|
---|
500 |
|
---|
501 | - corelib: Fixed unnecessary access to removable drives and a long delay and
|
---|
502 | noice caused by it when showing a file open dialog in Qt applications.
|
---|
503 |
|
---|
504 |
|
---|
505 | Beta 4 (11-11-2009)
|
---|
506 |
|
---|
507 | Improvements:
|
---|
508 |
|
---|
509 | - Added sound support (implemented QSound class).
|
---|
510 |
|
---|
511 | - Added system tray support (QSystemTrayIcon class). This support requires
|
---|
512 | the Extended system tray XCenter plugin to be installed. See the note above
|
---|
513 | on how to compile and install this plugin.
|
---|
514 |
|
---|
515 | - Enabled QPlugin support on OS/2. This in turn enables SVG support for
|
---|
516 | QIcon (which is built as a Qt plugin DLL by default).
|
---|
517 |
|
---|
518 | - Better widget modality support (widgets blocked by modality cannot be
|
---|
519 | activated and moved using the mouse and the title bar anymore).
|
---|
520 |
|
---|
521 | - Added support for 'console' and 'windows' CONFIG options in .pro files.
|
---|
522 | Now, if 'windows' is present, the target executable will have the WINDOWAPI
|
---|
523 | attribute set which effectively makes it a PM application. This, in
|
---|
524 | particular, disables standard input, output and error streams so that when
|
---|
525 | started, the application will not have a console window attached to it.
|
---|
526 | By default, 'console' mode is active unless you perform a release build and
|
---|
527 | the application is linked against the QtGui library ('QT = gui' in .pro),
|
---|
528 | in which case the default is 'windows'.
|
---|
529 |
|
---|
530 | - Improved paint speed in Qt windows which should increase overall graphical
|
---|
531 | UI performance by 10%-20% in Qt4 applications.
|
---|
532 |
|
---|
533 | - Implemented setting window icons for top-level windows (using
|
---|
534 | QWidget::setWindowIcon()).
|
---|
535 |
|
---|
536 | - Added LxLite support to provide compression for executables and DLLs. The
|
---|
537 | compression is controlled by the 'exepack' CONFIG option which is turned on
|
---|
538 | by default for release builds if the LxLite executable is present in PATH
|
---|
539 | during the configure.cmd invocation. The compression may be turned off on a
|
---|
540 | per-project basis by adding a 'CONFIG -= exepack' line to the .pro file.
|
---|
541 |
|
---|
542 | - Improved the section of this README.OS2 file that describes how to properly
|
---|
543 | set the LANG variable to have correct national characters in file names and
|
---|
544 | in window titles of Qt applications.
|
---|
545 |
|
---|
546 | Fixes:
|
---|
547 |
|
---|
548 | - QProcess: The executable's path was not always added to BEGINLIBPATH.
|
---|
549 |
|
---|
550 | - Fixed-size top-level widgets could not be moved.
|
---|
551 |
|
---|
552 | - Application crash after pressing a button in a dialog window that resizes
|
---|
553 | this dialog (for example, makes it bigger to show more information).
|
---|
554 |
|
---|
555 | - Resizing top level windows using the top border broke mouse coordinates so
|
---|
556 | that Qt tought you pressed the mouse button in a different place of the
|
---|
557 | window than where you actually did it.
|
---|
558 |
|
---|
559 | - Events posted with QCoreApplication::postEvent() were only processed upon
|
---|
560 | receiving a next message from the system. This caused funny delays such as
|
---|
561 | controls in a Qt window still indicating the input focus (the dotted
|
---|
562 | rectangle) after the window was deactivated and losing this indication only
|
---|
563 | when the mouse pointer was moved over the window.
|
---|
564 |
|
---|
565 | - Don't replay mouse button press on a push button that is showing a popup
|
---|
566 | menu but instead hide the popup menu and unpress the button to get more
|
---|
567 | native look and feel.
|
---|
568 |
|
---|
569 | - Deactivating the window with a push button showing a popup menu would hide
|
---|
570 | the popup but leave the button pressed.
|
---|
571 |
|
---|
572 | - Fixed incorrect Qt dirty widget region calculation when processing WM_PAINT
|
---|
573 | messages. This fixes a lot of redraw problems (menu items in the main menu
|
---|
574 | bar, text in combo-boxes, various redraw problems in smplayer when switching
|
---|
575 | interfaces and going to/from fullscreen, and similar).
|
---|
576 |
|
---|
577 |
|
---|
578 | Beta 3 (17-10-2009)
|
---|
579 |
|
---|
580 | Improvements:
|
---|
581 |
|
---|
582 | - Added proper font support. All outline (scalable) fonts visible in the Font
|
---|
583 | Palette should be now recognized by Qt. The fonts are hinted and antialiased
|
---|
584 | using the Freetype2 library when drawing text.
|
---|
585 |
|
---|
586 | - System fonts and colors are now used by default for Qt widgets.
|
---|
587 |
|
---|
588 | - configure.cmd now generates the main Makefile to simplify building of Qt.
|
---|
589 |
|
---|
590 | - corelib: QProcess: Implemented child termination detection.
|
---|
591 |
|
---|
592 | - corelib: QProcess: Implemented redirection to another QProcess.
|
---|
593 |
|
---|
594 | - corelib: QProcess now uses native pipes for stream redirection. This fixes
|
---|
595 | various issues like 'Socket operation on non-socket' errors during
|
---|
596 | parent-child communication.
|
---|
597 |
|
---|
598 | - corelib: QProcess: Make sure that the directory containing the executable
|
---|
599 | file is always searched (first) for DLLs needed by this executable. This
|
---|
600 | makes it unnecessary to change the current directory to the executable's
|
---|
601 | directory or add it to LIBPATH before starting the Qt application.
|
---|
602 |
|
---|
603 | - corelib: QProcess can now start applications of different type (e.g. PM
|
---|
604 | applications from text-mode applications) directly.
|
---|
605 | QProcess::startDetached() also works.
|
---|
606 |
|
---|
607 | - qmake: In debug_and_release mode, 'release-(all|clean|distclean|install|
|
---|
608 | uninstall)' and 'debug-(all|clean|distclean|install|uninstall)' make
|
---|
609 | targets are now available.
|
---|
610 |
|
---|
611 | Fixes:
|
---|
612 |
|
---|
613 | - Doing 'make clean' could result into a hang due to CMD.EXE command line
|
---|
614 | length limitation.
|
---|
615 |
|
---|
616 | - corelib: Fixed: QProcess: Lost data during stream redirection.
|
---|
617 |
|
---|
618 | - corelib: QSettings could sometimes distort data when saving it to the
|
---|
619 | registry (by replacing some characters with codes 0x80 and above with '?').
|
---|
620 |
|
---|
621 |
|
---|
622 | Beta 2 (17-09-2009)
|
---|
623 |
|
---|
624 | Improvements:
|
---|
625 |
|
---|
626 | - Ported the network module (QtNetwork4.dll) and added to the default build.
|
---|
627 |
|
---|
628 | - Added modules sql, svg, xmlpatterns, scripttools, plugins to the default
|
---|
629 | build.
|
---|
630 |
|
---|
631 | - gui: Added recognition of dead keys which makes it possible to type
|
---|
632 | umlauts and other accented characters that require composition.
|
---|
633 |
|
---|
634 | - gui: Implemented standard cursor shapes in Qt applications.
|
---|
635 |
|
---|
636 | Fixes:
|
---|
637 |
|
---|
638 | - qmake: Fixed the trailing slash problem which caused qmake to generate
|
---|
639 | incorrect makefiles and fail to build the Qt library on some platforms.
|
---|
640 |
|
---|
641 | - configure.cmd: Return to the root source tree directory after building
|
---|
642 | qmake.
|
---|
643 |
|
---|
644 | - qmake: Automatically use different link flags when linking qmake with WLINK.
|
---|
645 |
|
---|
646 | - qmake: Recognize TARGET_SHORT that allows to specify a short DLL name
|
---|
647 | (vital for OS/2 which reqires DLL names to be in 8x3 format).
|
---|
648 |
|
---|
649 | - build: Set short DLL names for Qt modules on OS/2 using TARGET_SHORT.
|
---|
650 |
|
---|
651 | - corelib: Various fixes to file system classes that deal with the file name
|
---|
652 | case (which should be ignored on OS/2) and forward and back slashes.
|
---|
653 |
|
---|
654 | - corelib: Fixed: QMutex could let more than one thread access the protected
|
---|
655 | resource.
|
---|
656 |
|
---|
657 | - corelib: Standard stream redirection in QProcess should now work for
|
---|
658 | kLIBC-based child processes. Redirection for all other applications
|
---|
659 | (such as CMD.EXE) will be added later (seems to be a kLIBC bug/feature).
|
---|
660 |
|
---|
661 | - gui: Fixed erroneous QFileDialog behavior (duplicate entires in the list,
|
---|
662 | incomplete contents of the root directory of the current drive).
|
---|
663 |
|
---|
664 | - gui: Fixed: Ctrl+A..Z should generate characters with codes 0x01-0x1F.
|
---|
665 |
|
---|
666 | - gui: Fixed: Close popups when resizing/moving the top level window.
|
---|
667 |
|
---|
668 | - gui: Enabled actual enforcing min/max Qt widget constraints for top-level windows.
|
---|
669 |
|
---|
670 | - gui: Fixed child widget duplication when resizing top level widgets after
|
---|
671 | showing a popup; moving native child widgets should now work correctly.
|
---|
672 | This also fixed a number of redraw problems (for example, drawing the main
|
---|
673 | menu and tool bars in smplayer, moving tool bars around in other
|
---|
674 | applications such as textedit from the demo folder).
|
---|
675 |
|
---|
676 |
|
---|
677 | Beta 1 (29-08-2009)
|
---|
678 |
|
---|
679 | - First public release.
|
---|
