setValue of ScrollBar Don't work at first time

[sergio87]

Thanks!!
I had already tested, and didn't works.

I tried:

scrollAreaCandidate->horizontalScrollBar()->update();
scrollAreaCandidate->update();
scrollAreaCandidate->horizontalScrollBar()->repaint();

scrollAreaCandidate->horizontalScrollBar()->update();
scrollAreaCandidate->update();
scrollAreaCandidate->horizontalScrollBar()->repaint();

To copy to clipboard, switch view to plain text mode 

But nothing works!!!
