1Here is a list of (major) changes in Qt from 0.96 to 0.98.
2As usual, we fixed some bugs and improved the documentation.

5*************** Changes that might affect runtime behavior *****************
6
7QWidget:
8--------
9  setMinimumSize() and setMaximumSize() now force the widget to
10  a legal size.  resize() and setGeometry() obey the widget's
11  minimum/maximum size.
12
13  The default behaviour of QWidget::closeEvent is now to hide the widget,
14  not to delete it as before (which was potentially dangerous). This means
15  that if you have a top level widget and the user closes it via the close
16  box, it will now hide itself if you have not reimplemented closeEvent().
17  See the QWidget::closeEvent() and QCloseEvent documentation for details.
18
19  (There are other changes in QWidget, see below)

21
22*************** Changes that might generate compile errors *****************
23**************           when compiling old code           *****************
24
25Disabled copy constructors and operators=
26-----------------------------------------
27  Copy constructors and operators= are disabled in the classes that cannot
28  be copied (this includes all classes that inherit from QObject). This
29  will let the compiler find bugs in your code, you'll get compile time
30  errors where you most probably would have gotten core dumps before.
31  This change has been done in the following classes:
32
33    QAccel QApplication QBuffer QButton QButtonGroup QCheckBox QClipboard
34    QComboBox QConnection QDataStream QDialog QFile QFileDialog QFrame
35    QGroupBox QIODevice QImageIO QLCDNumber QLabel QLineEdit QListBox
36    QMenuBar QMenuData QMenuItem QMessageBox QMetaObject QObject
37    QPSPrinter QPaintDevice QPainter QPicture QPopupMenu QPrintDialog
38    QPrinter QPushButton QRadioButton QRangeControl QScrollBar QSignal
39    QSocketNotifier QTableView QTextStream QTimer QWidget QWindow
40
41  The other classes all have sensible copy constructors and operators=.
42
43QDate:
44------
45  These were protected, now private:
46	static const char *monthNames[];
47 	static const char *weekdayNames[];
48	uint  	 jd;
49
50QListBox:
51---------
52  The internals of QListBox are completely reworked. Definition of custom
53  QListBoxItems is now much easier. This is *not* compatible with the old
54  way of defining custom QLBItems. See the QListBoxItem documentation for
55  details.
56
57QTime:
58------
59  This was protected, now private:
60	uint   ds;
61
62*************** Type changes that might generate warnings: *****************

64none
65
66*****************         Obsoleted functions         **********************
67
68none
69
70***************** All other changes from 0.96 to 0.98 **********************
71
72moc:
73----
74  Moc previously gave a syntax error when the word "class" was found
75  in a string outside a class declaration. This bug has now been
76  fixed.
77
78  More moc arguments, check the manpage for details.
79
80QFont:
81------
82  Two new convenience functions; bold() and setBold().
83
84QLabel:
85-------
86  setMargin() and margin() are new. setMargin() specifies a minimum margin
87  when the label contents are justified.
88
89QWidget:
90--------
91  You can specify a custom widget frame for top level widgets, including
92  no frame at all. See the widget constructor doc. for details.
93
94  Qt now has enter and leave events. Reimplement the virtual functions
95  void enterEvent( QEvent * ) and void leaveEvent( QEvent * ) to receive
96  events when the mouse cursor leaves or enters the visible part of the
97  widget.
