Changing Opacity in Qlabel

[desch]

Hi Everybody,

I try to change the opacity in QLabel.
Using the paintEvent with this kind of code:

void myLabel::paintEvent(QPaintEvent * e)
{
 
	QPainter p(this);
 
	// if pixmap
	if (! pixmap()->isNull()) 
		p.drawPixmap(pixmap()->rect(), * pixmap());
 
p.setOpacity(0.5); 
 
	// if Text
	if (! text().isEmpty()) 
		p.drawText(rect(), text());
 
}

void myLabel::paintEvent(QPaintEvent * e)
{
	
	QPainter p(this);
		
	// if pixmap
	if (! pixmap()->isNull()) 
		p.drawPixmap(pixmap()->rect(), * pixmap());

p.setOpacity(0.5); 

	// if Text
	if (! text().isEmpty()) 
		p.drawText(rect(), text());
	
}

To copy to clipboard, switch view to plain text mode 

The aim is just to change the opacity level ; The problem with this code is that , I have to redraw everything manually : style , pixmap position, text position...
it's not so easy...

If someone has something more easy, it will be fine

Thanks to all

David
