How to set background without stylesheets?

[smoon]

Hi,

how can I set the background of a button without using stylesheets? I tried to do this with something like that:

pushbutton_ontop->setAutoFillBackground(true);
pushbutton_ontop->setBackgroundRole(QPalette::Button);
QPalette p = pushbutton_ontop->palette();
p.setColor(QPalette::Button, Qt::red);
pushbutton_ontop->setPalette(p);

pushbutton_ontop->setAutoFillBackground(true);
pushbutton_ontop->setBackgroundRole(QPalette::Button);
QPalette p = pushbutton_ontop->palette();
p.setColor(QPalette::Button, Qt::red);
pushbutton_ontop->setPalette(p);

To copy to clipboard, switch view to plain text mode 

But with no luck.

If I use stylesheets I can set the background color, but the whole button style is gone after that

Hope someone has a good idea...
