[Qt-interest] problem with porting 'repaint' to Qt4

[Mahmood Naderan]

> Isnt that what the doc says to do…
 
Accoring to manual, there are 4 overloaded function for QWidget::repaint:
 
void QWidget::repaint () [slot]
void QWidget::repaint ( int x, int y, int w, int h )
void QWidget::repaint ( const QRect & r )
void QWidget::repaint ( const QRegion & rgn )
 
in previous version it is possible to pass a bool argument. I have not any idea about converting
a bool to QRect | QRegion | integer positions.

I don't want to turn on QT3_SUPPORT. I looked at the manual. You mean calling it without argument?
 
http://doc.trolltech.com/4.4/qwidget.html#repaint
  void QWidget::repaint ()

Don’t call repaint with a Boolean?
 
Look at the documentation and for the qwidget QT3 support members.. it tells you exactly what to call instead

Hello,
When I want to port a function to Qt4, I get an error:
 
function:
void do_paint() { if (Locked==0) repaint(FALSE); };
 
error:
error C2664: 'void QWidget::repaint(const QRect &)' : cannot convert parameter 1 from 'bool' to 'const QRect &'
        Reason: cannot convert from 'bool' to 'const QRect'
        No constructor could take the source type, or constructor overload resolution was ambiguous
 
How can I resolve it?
