Most +classes now have useful detailed descriptions. Documentation accuracy +and usability has been generally improved. + +Styles +------ + +In Qt 3.0.0 Beta2, only the Windows and Motif styles were implemented with +the new style API. Now the missing styles (MotifPlus, Platinum, SGI and +CDE) are included. + +MNG +--- + +Updated the libmng that is shipped with Qt to version 1.0.2. + +Wacom Tablet Support +-------------------- + +Fixes for Windows to solve the problem of creating a context for every +widget and the problem of opening the dialog and losing the ability to use +the tablet afterwards. + + +Qt Designer +======================================== + + - Added the ability to sort the property editor either by category + (default and old behaviour) or alphabetically. + + - Added the option "-nofwd" to uic which supresses the generation of + forward declarations for custom classes in the generated output. + +- The way how custom slots and editing these slots directly in the Qt + Designer is handled has been changed. Originally the code for these + slots was saved into the .ui XML file together with the user + interface description and the uic did put this code into the + generated source files. + Now, if code of custom slots is edited directly in the Qt Designer, + additionally to the <filename>.ui of a form, a <filename>.ui.h file + is created. The code is written into this source file now instead + of the .ui file. + This way the code of custom slots can be also easily edited outside + the Qt Designer without subclassing, and it is possible to edit it + both, in the Qt Designer and outside the Qt Designer without + conflicts, as this is a plain text C++ file. + Uic now automatically includes this source file into the generated + sources (if it exists) and, in this case, does not create empty + stubs for the custom slots in the generated sources anymore. So + this code file has not to be added to the project Makefile. If the + source file does not exist, uic falls back to the old behavior and + creates the empty stubs in the generated source. + If a user does not want to subclass to implement the custom slots, + but also does not want to edit the code of the custom slots in the + Qt Designer, it is possible to always create the <formname>.ui.h + for a form (even if it was not edited in the Qt Designer) and edit + that file in a seperate editor. This feature can be configured in + the project settings dialog. + This way, the old approach of subclassing keeps working (and all + old .ui files keep working without any change). Also, for users of + the previous Qt 3.0 Beta versions, Qt Designer can still read the + .ui files which contain code. So also .ui files created with Qt 3.0 + Beta versions of the Qt Designer keep working without any change. + Details about the possible concepts which can be used to add code + to a form created by the Qt Designer (subclassing and uic + + <filename>.ui.h) and related information about project management + can be found in the chapter about new features in Qt Designer 3.0 + in the Qt Designer manual. + + +Qt Functions +======================================== + +QApplication +------------ + + - flush() no longer calls sendPostedEvents(), as this might be unsafe + under certain circumstances. + +QDataTable +---------- + + - Now uses the new row selection mode of QTable. + +QDomDocument +------------ + + - Fixed the toString() function to work properly with namespaces. + - In Qt 3.0.0 Beta2, there was a workaround for Microsoft's XML parser, + so that the toString() function did not output a doctype that consists + only of the name. This workaround is semantically wrong; it was + reverted. + +QDateEdit +--------- + + - Fixed wrong default size policy and missing size hint. + - Improved focus and tab handling. + +QEffects +-------- + + - Tooltips and popup menus scroll and fade again + +QTable +------ + + - Fixed right mouse button handling. + - Implemented row selection modes. This implied adding the new enum values + SingleRow and MultiRow to the enum SelectionMode. + - Doubleclick clears selections completely now. + - Allow different focus styles, namely FollowStyle (draw it as the style + tells you) and SpreadSheet (draw it as it is done in common spreadsheet + programs). + +New functions: + virtual void setFocusStyle( FocusStyle fs ); + FocusStyle focusStyle() const; + virtual QRect cellRect( int row, int col ) const; + +QTimeEdit +--------- + + - Fixed wrong default size policy and missing size hint. + - Improved focus and tab handling. + +QTextEdit +--------- + + - QTextCursor is an internal class, so the signal + cursorPositionChanged(QTextCursor*) is only of limited use. Added a + more useful signal in addition. + + - Overrides accelerators for all shortcuts used to edit text. + +New signal: + void cursorPositionChanged( int para, int pos ); + +QLineEdit +--------- + + - Overrides accelerators for all shortcuts used to edit text. + +QLibrary +-------- + + - Static overload for resolve as a convenience function. + +New function: + static void *resolve( const QString &filename, const char * ); + +QListView +--------- + + - A bug that was introduced in Qt 3.0.0 beta 2 made listviews with + lots of items very slow. This problem has been fixed. + +QProcess +-------- + + - exitStatus() did not work for negative values on Unix. This is fixed + now. + - Fixed problems on Unixware. + +QRichtext +--------- + + - Fixed searching backwards. + - Fixed some BIDI text-rendering problems. + +QSound +------ + + - Simplified the API to allow easier extension. + +New functions: + bool isAvailable(); + int loops() const; + int loopsRemaining() const; + void setLoops(int); + QString fileName() const; + bool isFinished() const; + +New slot: + void stop(); + +Removed function: + bool available(); + +QSpinBox +-------- + + - Spin box arrows were not updated correctly when the widget was + disabled/enabled. This problem is fixed now. + - Improved handling of the case when a spinbox accepts a value: now it + also accepts it if the spinbox loses focus or is hidden. + +QSqlCursor +---------- + + - Add functions to set the generated flag. This is used to avoid the + generation of malformed SQL statements. + +New functions: + void setGenerated( const QString& name, bool generated ); + void setGenerated( int i, bool generated ); + +QSqlDriver +---------- + + - Add new function hasFeature( QSqlDriver::DriverFeature ) const which + allows you to query whether the driver supports features like SQL + transactions or Binary Large Object fields. The functions + hasQuerySizeSupport(), canEditBinaryFields() and hasTransactionSupport() + are therefore obsolete and have been removed. + +New function: + bool hasFeature( QSqlDriver::DriverFeature ) const; + +Removed functions: + bool hasQuerySizeSupport() const; + bool canEditBinaryFields() const; + bool hasTransactionSupport() const; + +QSqlField +--------- + + - The bool argument of setNull() was removed since it does not make sense + to set a field to non null. + +QTabWidget +---------- + + - Use the functions below to add tool tips to the individual tabs in a + QTabWidget. + +New functions: + void removeTabToolTip( QWidget * w ); + void setTabToolTip( QWidget * w, const QString & tip ); + QString tabToolTip( QWidget * w ) const; + +QTabBar +------- + + - Use the functions below to add tool tips to the individual tabs in a + QTabBar. + +New functions: + void removeToolTip( int id ); + void setToolTip( int id, const QString & tip ); + QString toolTip( int id ) const; + +QTextStream +----------- + + - The global functions setw(), setfill() and setprecison() were deleted + since they conflict with the std classes. If you need the functionality, + use qSetW(), qSetFill() and qSetPrecision() instead. + +Removed functions: + QTSManip setw( int w ) + QTSManip setfill( int f ) + QTSManip setprecision( int p ) |
