How to remove/change the gradient of QToolButton without setStyleSheet

russe

I change the background color of my widget with this

palette = widget.palette()
palette.setColor(widget.backgroundRole(), QColor("red"))
widget.setPalette(palette)
widget.setAutoFillBackground(True)

But on a QToolButton the background look more "pink" than "red".
I try other "QStyleFactory" and some work correctly.
But if I use the default style on my ubuntu I had a gradient background and I doesn't had my color.

Can I remove or change the gradient of background.

PS. I try to change the background with setStyleSheet, it work. But my application always crash after a few change on same widget. I need to change the background color of many widget at the same time and many time on same widget.

Hi and welcome to devnet,

Do you have that only on Ubuntu ?

What desktop environment do you use ?
