Hey,

I'm working with a widget where I have inserted a QScrollArea. In this scroll I use the vertical and horizontal scrollbar as needed. However I want to change the size of them.
To achive my goal I have used these two sentences without seing any chage:

ui.scrollArea->verticalScrollBar()->setMinimumWidth (70);
ui.scrollArea->horizontalScrollBar()->setMinimumHeight(70);

Can anyone help me?
