QScrollArea - scrollbar arrows stylesheet, single step

[Tomasz]

Hello!

I've got some problem with styling scrollbar of QScrollArea. I've set stylesheet for QScrollArea:

QScrollBar:vertical {min-width: 40px; margin-right: 25px;}

QScrollBar:vertical {min-width: 40px; margin-right: 25px;}

To copy to clipboard, switch view to plain text mode 

But after that I can't see any arrows. I'm trying to change stylesheet of an arrows with:

QScrollBar::down-arrow:vertical, QScrollBar::up-arrow:vertical {background: white; width: 35px; height: 30px;}

QScrollBar::down-arrow:vertical, QScrollBar::up-arrow:vertical {background: white; width: 35px; height: 30px;}

To copy to clipboard, switch view to plain text mode 

But still can't see them. Any suggestions?

Solved the problem using stylesheet example.

One more. QScrollBar is part of QScrollArea. QScrollBar inherits setSingleStep() from QAbstractSlider - so, can I use It somehow for my QScrollArea to change single step?

thanks in advance
best regards
