[mickey]

hi,
your hint for QFIledialog was OK! But with a dialog create in designer this doens't work!!! what change?? thanks (usually the umbra of initPlainDialog is visible until all this instructions aren't exectute)...

void MainForm::fileNew()
{	
	initPlainDialog *initpd= new initPlainDialog();
	if(initpd->exec()){
		int vx = initpd->IPDSpinBoxX->value();
		int vy = initpd->IPDSpinBoxY->value();		
		if ((vx > 0 && vy > 0) && (vx*vy <=1024)) {
		qApp->processEvents();
		doSOmething //very long time
                  widget1->update(); //long time
}

void MainForm::fileNew()
{	
	initPlainDialog *initpd= new initPlainDialog();
	if(initpd->exec()){
		int vx = initpd->IPDSpinBoxX->value();
		int vy = initpd->IPDSpinBoxY->value();		
		if ((vx > 0 && vy > 0) && (vx*vy <=1024)) {
		qApp->processEvents();
		doSOmething //very long time
                  widget1->update(); //long time
}

doSOmething //very long time

This blocks the event loop, so you must call QApplication::processEvents() inside it, for example in every iteration.
