|
13 Qt library |
|
14 ---------- |
|
15 |
|
16 Qt 3.3 is .NET enabled. This release shows how to use classes |
|
17 developed with Qt in a .NET environment. It includes an analysis of |
|
18 the different interoperability infrastructures provided by the .NET |
|
19 framework. An example demonstrates how to use both a manual approach |
|
20 with Microsoft's managed extensions to the C++ language, and also |
|
21 automated solutions based on COM and the ActiveQt framework to reuse |
|
22 native Qt classes and widgets in .NET projects. To learn more about Qt |
|
23 and .NET read the "Using Qt objects in Microsoft .NET" walkthrough |
|
24 found in the ActiveQt framework documentation. |
|
25 |
|
26 Qt 3.3 now supports IPv6 in addition to IPv4. New functions have been |
|
27 added for IPv6 support to QSocketDevice, QHostAddress and QDNns. |
|
28 |
|
29 Qt now includes a new tool class called QLocale. This class converts |
|
30 between numbers and their string representations in various languages. |
|
31 QLocale supports the concept of a default locale which allows a locale |
|
32 to be set globally for the entire application. |
|
33 |
|
34 Support for new 64bit platforms and compilers has been added for Qt |
|
35 3.3. Qt now supports Itanium on both Linux (Intel C++ compiler) and |
|
36 Windows (MSVC and Intel C++ Compiler). Qt 3.3 now also officially |
|
37 supports FreeBSD. |
|
38 |
|
39 Qt 3.3 also supports precompiled headers for Windows, Mac OS X and |
|
40 X11. To use precompiled headers when compiling your Qt application |
|
41 simply add PRECOMPILED_HEADER and then specify the header file to |
|
42 precompile in your .pro file. To learn more about precompiled headers |
|
43 see the "Using Precompiled Headers" chapter in the qmake User Guide. |
|
44 |
|
45 Two new database drivers have been added to the SQL module, InterBase |
|
46 and SQLite. This makes it possible to write database applications that |
|
47 do not require a database server. SQLite is provided in the Qt 3.3 |
|
48 distribution and can be enabled with either -qt-sql-sqlite or |
|
49 -plugin-sql-sqlite. The InterBase plugin also works with Firebird, the |
|
50 open source version of InterBase. |
|
51 |
|
52 QWidget has a new function setWindowState() which is used to make a |
|
53 widget maximized, minimized, etc. This allows individual settings for |
|
54 the minimized/maximized/fullscreen properties. |
|
55 |
|
56 Support for semi-transparent top-level widgets on Mac OS X and Windows |
|
57 2000/XP has also been added. |
|
58 |
|
59 A new example, qregexptester, has been added that makes it easy to |
|
60 test QRegExps on sample strings. |
|
61 |
|
62 Qt 3.3 includes in addition to this, numerous bug fixes and |
|
63 improvements. Special thanks goes to KDE for their reports and |
|
64 suggestions. |
|
65 |
|
66 |
|
67 Qt/Embedded |
|
68 ----------- |
|
69 |
|
70 Added support for SNAP graphics drivers from SciTech Software. This |
|
71 gives access to accelerated drivers for more than 150 graphics |
|
72 chipsets. |
|
73 |
|
74 |
|
75 Qt/Mac |
|
76 ------ |
|
77 |
|
78 QAccessible support has been introduced (implemented in terms of Apple's |
|
79 Universal Access API). |
|
80 |
|
81 Added support for Xcode project files in qmake. |
|
82 |
|
83 Added Tablet support for Mac OS X. |
|
84 |
|
85 Numerous visual improvements. |
|
86 |
|
87 |
|
88 Qt/X11 |
|
89 ------ |
|
90 |
|
91 Added support for Xft2 client side fonts on X servers without the |
|
92 RENDER extension. |
|
93 |
|
94 Added a new configure option (-dlopen-opengl) which will remove the |
|
95 OpenGL and Xmu library dependencies in the Qt library. The functions |
|
96 used by Qt in those libraries are resolved manually using dlopen() |
|
97 when this option is used. |
|
98 |
|
99 Improved support for the Extended Window Manager Hints. |
|
100 |
|
101 |
|
102 Qt/Windows |
|
103 ---------- |
|
104 |
|
105 Added support for Windows Server 2003 (Win64/Itanium). |
|
106 |
|
107 |
|
108 Qt Motif Extension |
|
109 ------------------ |
|
110 |
|
111 Clipboard operations now work between Qt and Motif widgets in the same |
|
112 application. Click-to-focus works with Motif widgets that are children |
|
113 of a QMotifWidget. |
|
114 |
|
115 |
|
116 ActiveQt Extension |
|
117 ------------------ |
|
118 |
|
119 Two new functions, QAxFactory::startServer() and |
|
120 QAxFactory::stopServer(), can be used to start and stop an |
|
121 out-of-process ActiveQt server at runtime. The new functions |
|
122 QAxFactory::serverDirPath() and QAxFactory::serverFilePath() return |
|
123 the location of the COM server binary. Server binaries no longer |
|
124 need to implement a main() entry point function. A default |
|
125 implementation is used for out-of-process servers. IClassFactory2 |
|
126 is supported for the development of licensed components, and |
|
127 QAxFactory supports the creation of non-visual COM objects. Class |
|
128 specific information can be provided directly in the C++ class |
|
129 declaration using the Q_CLASSINFO macro to control how objects and |
|
130 controls are registered and exposed. New helper classes and macros |
|
131 are avialable to make it even easier to expose object classes (see the |
|
132 QAxServer documentation for details). |
|
133 |
|
134 COM objects developed with ActiveQt are now supported in a wider range |
|
135 of clients, including Microsoft Office applications and .NET. Examples |
|
136 that demonstrate how to use the Qt objects from the examples in .NET |
|
137 languages like C# are included. QStringList is supported as a type, |
|
138 and QRect, QSize and QPoint are now supported datatypes for control |
|
139 properties and as reference parameters. Saving the controls to a |
|
140 storage or stream now includes the version number of the QDataStream |
|
141 used for the serialization (note that this might break existing |
|
142 storages). |
|
143 |
|
144 The QAxContainer library is now static even for shared configurations |
|
145 of Qt. This simplifies deployment and allows using both QAxServer and |
|
146 QAxContainer in one project, i.e. an OLE automatable application that |
|
147 uses COM objects itself. The semantics of QAxBase::setControl() have |
|
148 been extended to allow creating of COM objects on remote machines via |
|
149 DCOM, to create controls requiring a license key and to connect to |
|
150 already running objects. The implementation of QAxBase::dynamicCall() |
|
151 has been improved to support passing of parameter values directly in |
|
152 the function string. Three new classes, QAxScript, QAxScriptManager |
|
153 and QAxScriptEngine, can be used to script COM objects from within Qt |
|
154 applications using Windows Script Host. |
|
155 |
|
156 SAFEARRAY(BSTR) parameters are supported as QStringList. Calling COM |
|
157 object methods with out-parameters of type short, char and float is |
|
158 now supported (the parameters are of type int& and double& in the Qt |
|
159 wrapper), and QVariants used for out-parameters don't have to be |
|
160 initialized to the expected type. Calling QByteArray functions in |
|
161 out-of-process controls no longer returns an error code. The control's |
|
162 client side is set to zero when the container releases the control. |
|
163 |
|
164 |
|
165 Qt Designer |
|
166 ----------- |
|
167 |
|
168 Qt Designer, Qt's visual GUI builder, has received some speed |
|
169 optimizations, along with minor improvements to the menu editor. |
|
170 |
|
171 |
|
172 Qt Assistant |
|
173 ------------ |
|
174 |
|
175 Qt Assistant now saves the states of the tab bars between runs. This |
|
176 enables users to start browsing where they ended their previous |
|
177 assistant session. |
|
178 |
|
179 Shortcuts for Find Next (F3) and Find Previous (Shift+F3) have been |
|
180 implemented. |
|
181 |
|
182 |
|
183 Compilers |
|
184 --------- |
|
185 |
|
186 Qt 3.3 adds support for two new compilers. The Intel C++ compiler is |
|
187 supported on Windows, Linux and FreeBSD. GNU gcc is supported on |
|
188 Windows using MinGW. |
|
189 |
|
190 Qt 3.3 no longer officially supports the Sun WorkShop 5.0 compiler or the |
|
191 SGI MIPSpro o32 mode. |
|
192 |
|
193 |

|
218 ShowMinimized, ShowMaximized and ShowFullScreen. |
|
219 |
|
220 - QHeader |
|
221 The sizeChange() signal is emitted when the section sizes are |
|
222 adjusted by double clicking. |
|
223 |
|
224 - QHostAddress |
|
225 Added new constructor for IPv6 and new functions |
|
226 isIPv6Address() and toIPv6Address(). Obsoleted the functions |
|
227 isIp4Addr() and ip4Addr(), replacing them with isIPv4Address() |
|
228 and toIPv4Address(). |
|
229 |
|
230 - QIconView |
|
231 Improved keyboard search to behave like QListView. |
|
232 |
|
233 - QListView |

234 Improved alignment for text in QListViewItems. Right aligned |
|
235 text now has the ellipsis on the left. |
|
236 Keyboard search now uses the sort column as the column to |
|
237 start searching in. |
|
238 Improved branch drawing. |
|
239 |
|
240 - QLocale [new] |
|
241 This new tool class converts between numbers and their string |
|
242 representations in various languages. |

|
272 rather than with the text() color. |
|
273 |
|
274 - QString |
|
275 Added support for %lc and %ls to sprintf(). %lc takes a |
|
276 Unicode character of type ushort, %ls takes a zero-terminated |
|
277 array of Unicode characters of type ushort (i.e. const |
|
278 ushort*). Also added support for precision (e.g. "%.5s"). |
|
279 Changed arg() to support "%L1" for localized conversions. |
|
280 Windows only: QString::local8Bit() now returns an empty |

|
298 |
|
299 - QVariant |
|
300 Comparison between variants where one of the variants is a |
|
301 numeric value will compare on the numeric value. Type casting |
|
302 between different variants is more consistent. |
|
303 |
|
304 - QWidget |
|
305 Added setWindowOpacity() and windowOpacity() to support |
|
306 transparent top-level widgets on Windows and Mac. |
|
307 Added windowState() and setWindowState() to allow individual |
|
308 setting of the minimized/maximized/fullscreen properties. |
|
309 |
|
310 - QWindowsStyle |
|
311 Qt supports toggling of the accelerator underlines using the |
|
312 Alt-key on Windows 98, 2000 and later. On other platforms this |
|
313 change has no effect. |
