Problem with code (probably repaintinng label)

[hakermania]

Hello all, i would like to tell me what's wrong with this code

for(int a=9;a>=0;a--)
	{
	ui->label->setText((QString)a);
	ui->label->repaint();
	sleep(1);
	}

for(int a=9;a>=0;a--)
	{
	ui->label->setText((QString)a);
	ui->label->repaint();
	sleep(1);
	}

To copy to clipboard, switch view to plain text mode 

where sleep(const int) is the function from the iostream library and waits const int seconds till the next step.
The label isn't repainted :/
So, actually it is a label that must change its value every second. Thanks

For anybody following this thread, the solution is to use a QTimer

nice

By the way: if there is no special reason always use update() not repaint(). Further a follow up lecture: http://doc.trolltech.org/qq/qq27-responsive-guis.html

I would say that casting int to QString is the problem.
