Here is a list of changes in Qt from 0.91 to 0.92. Also look out
|
|
for a few new classes; QPrinter, QFileDialog, QDir and QFileInfo.
|
|
|
|
|
|
QApplication:
|
|
-------------
|
|
Use setMainWidget( x ), not exec( x ).
|
|
|
|
QString:
|
|
--------
|
|
upper(), lower(), stripWhiteSpace() and simplifyWhiteSpace() etc.
|
|
do NOT modify the string, instead they return a new string.
|
|
|
|
QList and QVector:
|
|
------------------
|
|
Changed argument in QList::toVector() from reference to pointer
|
|
Changed argument in QVector::toList() from reference to pointer
|
|
Removed QVector::apply()
|
|
Removed QList::apply()
|
|
|
|
QPainter:
|
|
---------
|
|
pen(), brush() and font() no longer returns references.
|
|
You cannot do this any longer:
|
|
QPainter p;
|
|
...
|
|
p.pen().setColor( red );
|
|
p.brush().setStyle( NoBrush );
|
|
Instead, set a new pen or brush:
|
|
p.setPen( red );
|
|
p.setBrush( NoBrush );
|
|
This enables us to do better optimization, particularly for complex
|
|
programs.
|
|
|
|
QFile, QFileInfo (new):
|
|
-----------------------
|
|
Removed QFile::setFileName,
|
|
QFile::isRegular => QFileInfo::isFile
|
|
QFile::isDirectory => QFileInfo::isDir
|
|
QFile::isSymLink => QFileInfo::isSymLink
|
|
|
|
Q2DMatrix/QWMatrix:
|
|
---------
|
|
Q2DMatrix has been replaced with QWMatrix (qwmatrix.h)
|
|
|
|
QPixmap:
|
|
--------
|
|
enableImageCache() renamed to setOptimization().
|
|
Optimization is now default ON. See doc for other optimization functions.
|
|
|
|
QImage:
|
|
-------
|
|
scanline() => scanLine()
|
|
|
|
QLineEdit/QLCDNumber:
|
|
---------------------
|
|
signal textChanged( char * ) => textChanged( const char * );
|
|
slot display( char * ) => display( const char * )
|
|
|

|
|

|
|

|
|

QFontMetrics and QFontInfo:
|
|
---------------------------
|
|
Get font metrics from QWidget::fontMetrics() and QPainter::fontMetrics().
|
|
Get font info from QWidget::fontInfo() and QPainter::fontInfo().
|
|
The QFontMetrics(QFont) constructor no longer works.
|
|
We had to do these changes to support printing and Windows.
|
|
|
|
|
|
There are more changes, left out because we consider them minor and
|
|
uninteresting or because we forgot to mention them. :)
