This means + that if you have a top level widget and the user closes it via the close + box, it will now hide itself if you have not reimplemented closeEvent(). + See the QWidget::closeEvent() and QCloseEvent documentation for details. + + (There are other changes in QWidget, see below) + + +*************** Changes that might generate compile errors ***************** +************** when compiling old code ***************** + +Disabled copy constructors and operators= +----------------------------------------- + Copy constructors and operators= are disabled in the classes that cannot + be copied (this includes all classes that inherit from QObject). This + will let the compiler find bugs in your code, you'll get compile time + errors where you most probably would have gotten core dumps before. + This change has been done in the following classes: + + QAccel QApplication QBuffer QButton QButtonGroup QCheckBox QClipboard + QComboBox QConnection QDataStream QDialog QFile QFileDialog QFrame + QGroupBox QIODevice QImageIO QLCDNumber QLabel QLineEdit QListBox + QMenuBar QMenuData QMenuItem QMessageBox QMetaObject QObject + QPSPrinter QPaintDevice QPainter QPicture QPopupMenu QPrintDialog + QPrinter QPushButton QRadioButton QRangeControl QScrollBar QSignal + QSocketNotifier QTableView QTextStream QTimer QWidget QWindow + + The other classes all have sensible copy constructors and operators=. + +QDate: +------ + These were protected, now private: + static const char *monthNames[]; + static const char *weekdayNames[]; + uint jd; + +QListBox: +--------- + The internals of QListBox are completely reworked. Definition of custom + QListBoxItems is now much easier. This is *not* compatible with the old + way of defining custom QLBItems. See the QListBoxItem documentation for + details. + +QTime: +------ + This was protected, now private: + uint ds; + +*************** Type changes that might generate warnings: ***************** + +none + +***************** Obsoleted functions ********************** + +none + +***************** All other changes from 0.96 to 0.98 ********************** + +moc: +---- + Moc previously gave a syntax error when the word "class" was found + in a string outside a class declaration. This bug has now been + fixed. + + More moc arguments, check the manpage for details. + +QFont: +------ + Two new convenience functions; bold() and setBold(). + +QLabel: +------- + setMargin() and margin() are new. setMargin() specifies a minimum margin + when the label contents are justified. + +QWidget: +-------- + You can specify a custom widget frame for top level widgets, including + no frame at all. See the widget constructor doc. for details. + + Qt now has enter and leave events. Reimplement the virtual functions + void enterEvent( QEvent * ) and void leaveEvent( QEvent * ) to receive + events when the mouse cursor leaves or enters the visible part of the + widget. + |
