Solved Scale QPixmap has no effect
-
Hi guys,
I am coding an app for my android tablet. I am trying to set a png image as background to my mainwindow. However, the scaled() fct doesn't resize the QPixmap to the right size.
Here is my code :
QPixmap bkgnd = QPixmap(":/images/0.png"); QPixmap scaledPixmap = bkgnd.scaled(this->width(), this->height(),Qt::IgnoreAspectRatio, Qt::SmoothTransformation); QPalette palette; QBrush brush = QBrush(scaledPixmap); palette.setBrush(QPalette::Background, brush); this->setPalette(palette);
Thank you for your help !

Hi and welcome to devnet,
Are you by any chance doing that in the constructor ? If so that's normal. When the constructor is called the widget has no idea about the size it's going to have. You should rather do that in a showEvent reimplementation or maybe resizeEvent.

Could you illustrate the issue with a screenshot, as we can have no idea what the correct size is?
