[Qt-interest] Updating the QPlainTextEdit's background color

[NoRulez]

Hi,

 

I’m trying to set the background color of a QPlainTextEdit as followed:

 

QPalette pal = palette();

pal.setColor(QPalette::Base, Qt::yellow);

setPalette(pal);

 

But the background color doesn't change.

 

I also tried each of the following functions after “setPalette(pal);”, but
the result is the same (which means that the background color isn't changed)

.) update();

.) repaint();

.) viewport()->update();

 

So, which method can I call to change the background color immediately.

 

Thanks in advance

 

Best Regards

NoRulez
