Reduce painting area of qwidget.

[tokafr]

Hello All!
I have a qtableview object and set my custom horizontal scroll bar(inherits QScrollBar)
with

setHorizontalScrollBar(new MyScrollBar(this));

But I have problem, when scroll changes the range it gets repainted by the table So scrollbar is not visible. I want to reduce the painting area of qtableview to avoid scroll repainting. How is that possible?
thank you.

hi
I have never tried this myself so might be silly question,
If you set the qtableview to always show horz scrollbar (Qt::ScrollBarPolicy)
and then replace it with your own. the size should fit?

Or is because your new scrollbar is bigger? (than the std one)

the docs says
"When a scroll bar becomes visible again, the viewport shrinks in order to make room for the scroll bar."

so it should just work by auto. So I wonder if the custom bar dont give correct size info?
