[Qt-interest] Set background color of a QPushButton for Windows XP

[Valentina Masi]

Hi all

In my Qt application I have to set the background color for some QPushButton to another color from default color.
My app runs in Windows XP and I need to use Windows XP style (not classic Windows style).

I tried as follows:

QPalette palette = myPushButton->palette();
QBrush brush(QColor(255, 0, 0, 255));  // red
brush.setStyle(Qt::SolidPattern);

palette.setBrush(QPalette::Active, QPalette::Button, brush);

palette.setBrush(QPalette::Inactive, QPalette::Button, brush);

palette.setBrush(QPalette::Disabled, QPalette::Button, brush);

myPushButton->setPalette(palette);  


But it works only if I set classic Windows style.

I also tried to use stylesheet but the problem remained.
 
Can anyone help me?

Thanks in advance
Valentina
