When size of viewport is defined?
-
Hello!
I'm writing app with QScrollArea and going to set scroll bars values. Here's a piece of code:
@
MyScrollArea::MyScrollArea() {
...
// create scrollarea's widget
CentralWidget = new QWidget(viewport());
setWidget(CentralWidget);// set scrollarea's widget geometry CentralWidget->setGeometry(0, 0, someWidth, someHeight); CentralWidget->show(); CentralWidget->repaint(); // get viewport size int viewWidth = viewport()->width(); int viewHeight = viewport()->height(); //--------------------------------------------
}@
And got incorrect size of viewport: viewWidth = 28, viewHeight = 98. I consider that it's not defined yet, is it right?. When will I be able to get correct size?

Here's an explanation of what may be happening to you:

You can likely use Volker's solution to overcome this.
Also, you can try calling show() first, then setGeometry() in your example, since you'll know someWidth and someHeight.

Thanks for reply! Maybe a bit later, but I'll try :)
