Repainting QScrollArea

[AlaaM]

I have a horizontal QScrollArea, loaded with a QLabel.
At some point I make changes to the QLabel and load it with shorter text.
The problem is that after I load the shorter text, the horizontal scroll bar is still showing (although not needed). It's still showing, fitting the previous text length. Note that I see the text changed successfully, but the scroll bar isn't updated as expected.

I tried the following as mentioned here:

QScrollArea::update()
QScrollArea::repaint()

QScrollBar::update()
QScrollBar::repaint()

QScrollArea()::viewport()->update();
QScrollArea()::viewport()->repaint();

None of them worked.

Hi,

Did you check that the size of the label changes after you set the text ?

Setting the widgetResizable property to true should do what you want. No need to call update or repaint. They mostly just invoke a paint event. They don't adjust sizes.
