1 Here is a list of changes in Qt from 0.91 to 0.92.  Also look out

     2 for a few new classes; QPrinter, QFileDialog, QDir and QFileInfo.

     3 

     4 

     5 QApplication:

     6 -------------

     7   Use setMainWidget( x ), not exec( x ).

     8 

     9 QString:

    10 --------

    11   upper(), lower(), stripWhiteSpace() and simplifyWhiteSpace() etc.

    12   do NOT modify the string, instead they return a new string.

    13 

    14 QList and QVector:

    15 ------------------

    16   Changed argument in QList::toVector() from reference to pointer

    17   Changed argument in QVector::toList() from reference to pointer

    18   Removed QVector::apply()

    19   Removed QList::apply()

    20 

    21 QPainter:

    22 ---------

    23   pen(), brush() and font() no longer returns references.

    24   You cannot do this any longer:

    25 	QPainter p;

    26 	...

    27         p.pen().setColor( red );

    28 	p.brush().setStyle( NoBrush );

    29   Instead, set a new pen or brush:

    30 	p.setPen( red );

    31 	p.setBrush( NoBrush );

    32   This enables us to do better optimization, particularly for complex

    33   programs.

    34 

    35 QFile, QFileInfo (new):

    36 -----------------------

    37   Removed QFile::setFileName, 

    38   QFile::isRegular   => QFileInfo::isFile

    39   QFile::isDirectory => QFileInfo::isDir

    40   QFile::isSymLink   => QFileInfo::isSymLink

    41 

    42 Q2DMatrix/QWMatrix:

    43 ---------

    44   Q2DMatrix has been replaced with QWMatrix (qwmatrix.h)

    45 

    46 QPixmap:

    47 --------

    48   enableImageCache() renamed to setOptimization().

    49   Optimization is now default ON.  See doc for other optimization functions.

    50 

    51 QImage:

    52 -------

    53   scanline() => scanLine()

    54 

    55 QLineEdit/QLCDNumber:

    56 ---------------------

    57   signal textChanged( char * ) => textChanged( const char * );

    58   slot   display( char * )     => display( const char * )

    59 

    60 QCursor:

    61 --------

    62     hourGlassCursor => waitCursor

    63 

    64 QButton and friends:

    65 --------------------

    66     QIconButton removed, setPixmap() added to QButton to replace QIconButton

    67 

    68 QTableWidget:

    69 -------------

    70     Renamed to QTableView (qtablevw.h)

    71     Using int to identify rows and columns, not long.

    72 

    73 QRangeControl:

    74 --------------

    75     Using int values, not long.

    76 

    77 QScrollBar:

    78 -----------

    79     Using int values, not long.

    80 

    81 QListBox:

    82 ---------

    83     removed setStrList(), use clear(); insertStrList( ... , 0 ); instead 

    84 

    85 QColor:

    86 -------

    87     setRGB => setRgb

    88     getRGB => rgb

    89     setHSV => setHsv

    90     getHSV => hsv

    91 

    92 QFontMetrics and QFontInfo:

    93 ---------------------------

    94     Get font metrics from QWidget::fontMetrics() and QPainter::fontMetrics().

    95     Get font info    from QWidget::fontInfo()    and QPainter::fontInfo().

    96     The QFontMetrics(QFont) constructor no longer works.

    97     We had to do these changes to support printing and Windows.

    98 

    99 

   100 There are more changes, left out because we consider them minor and

   101 uninteresting or because we forgot to mention them. :)
