As a special service "Fossies" has tried to format the requested text file into HTML format (style: standard) with prefixed line numbers. Alternatively you can here view or download the uninterpreted source code file.

    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. :)
