problem with msleep

[Reinexen]

Hi,
I'm having a problem with msleep function void QThread::msleep ( unsigned long msecs )
I dont really know how to use it.
I have a class "Labirynt" and a function in it: void Generate();
Something like this:

void Labirynt::Generate()
{
for(int i=10; i<100; i++)
    {
    //mathematical calculations (these are changing variables which are used in                                                      
    //    Labirynt::paintEvent [this is why i use update();])
   QThread::msleep(20);
    update();
    }
}

void Labirynt::Generate()
{
for(int i=10; i<100; i++)
    {
    //mathematical calculations (these are changing variables which are used in                                                      
    //    Labirynt::paintEvent [this is why i use update();])
   QThread::msleep(20);
    update();
    }
}

My Error:
c:/Qt/4.3.3/include/QtCore/../../src/corelib/thread/qthread.h:108: error: `static void QThread::msleep(long unsigned int)' is protected
labirynt.cpp:67: error: within this context

What should i do to make it work?
When i use sleep from standard library program hangs up.
When i use my own sleep function program hangs up.

Don't put your GUI thread into sleep, use QTimer instead.

Thanks.

This is what i did and it works with qmake 4.3:

void Labirynt::oncemore()
{
	loop++;
	Generate();
	update();
}
 
void Labirynt::Generate()
{
QTimer *timer = new QTimer(this);
connect(timer, SIGNAL(timeout()), this, SLOT(oncemore()));
 
    //mathematical calculations (these are changing variables which are used in                                                      
    //    Labirynt::paintEvent [this is why i use update();])
 
if(loop<120)
timer->singleShot(100, this, SLOT(oncemore()));
 
}

void Labirynt::oncemore()
{
	loop++;
	Generate();
	update();
}

void Labirynt::Generate()
{
QTimer *timer = new QTimer(this);
connect(timer, SIGNAL(timeout()), this, SLOT(oncemore()));

    //mathematical calculations (these are changing variables which are used in                                                      
    //    Labirynt::paintEvent [this is why i use update();])

if(loop<120)
timer->singleShot(100, this, SLOT(oncemore()));

}

It would be better if you had only one timer.
