Here is a list of (major) changes in Qt from 0.96 to 0.98.
|
|
As usual, we fixed some bugs and improved the documentation.
|
|
|
|
|
|
*************** Changes that might affect runtime behavior *****************
|
|
|
|
QWidget:
|
|
--------
|
|
setMinimumSize() and setMaximumSize() now force the widget to
|
|
a legal size. resize() and setGeometry() obey the widget's
|
|
minimum/maximum size.
|
|
|
|
The default behaviour of QWidget::closeEvent is now to hide the widget,
|
|
not to delete it as before (which was potentially dangerous). 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.
