QAbstractScrollArea

[ikuris]

Hello,

How can I put QAbstractScrollArea in ui. I am trying to draw shapes in it but I couldnt find any example and if you provide me with project or any usage of it it would be great.

Thanks a lot.

Hi
Why do you want to use QAbstractScrollArea ?

There is QScrollArea you can use directly.

If you want to have a scrollable paint area, you can simply use a custom widget as a content widget

I do need a lower version of qscrollarea and I am curious about its usage.
I will compare their usability afterwards.

I don't think you can put a QAbstractScrollArea in with Designer, else there would be an icon widget for it.

You can just add it to the layout with addWidget() but I couldnt override paintEvent of QAbstractScrollArea.
I tried drawing some rectangles in it but it didn't work.

Hi
Im not sure using QAbstractScrollArea is the correct way for a canvas that can scroll.
In QScrollArea the actual paint of the QScrollArea would be covered up by the content widget.
Not sure if same dont apply to QAbstractScrollArea :)
