how to determine geometry of a QFrame

[impeteperry]

Hi
I have a QFrame *frame A and I want to place a QFrame *helpFrame in it

emit displayHelpFunction( frameA, &helpFlag);
	frameA->show();

emit displayHelpFunction( frameA, &helpFlag);
	frameA->show();

To copy to clipboard, switch view to plain text mode 

and the code in the sub-frame is

void HelpFunction::slotDisplayHelpFunction( QFrame *sourceFrame, bool *flag )
{
	 if ( *flag == false)
	{
		helpFrame = new QFrame(  sourceFrame );
		helpFrame->setFrameShape( QFrame::StyledPanel );
		helpFrame->setGeometry( 10, 10, 200, 400 );
		teHelpBox= new QTextEdit( helpFrame );
		teHelpBox->setGeometry(10,10, 180, 380);
		teHelpBox->setPlainText( "Now is the time" );
		helpFrame->show();
		*flag = true;
	}
	else if ( *flag == true )
	{
		*flag = false;
		helpFrame->hide();
	}
}

void HelpFunction::slotDisplayHelpFunction( QFrame *sourceFrame, bool *flag )
{
	 if ( *flag == false)
	{
		helpFrame = new QFrame(  sourceFrame );
		helpFrame->setFrameShape( QFrame::StyledPanel );
		helpFrame->setGeometry( 10, 10, 200, 400 );
		teHelpBox= new QTextEdit( helpFrame );
		teHelpBox->setGeometry(10,10, 180, 380);
		teHelpBox->setPlainText( "Now is the time" );
		helpFrame->show();
		*flag = true;
	}
	else if ( *flag == true )
	{
		*flag = false;
		helpFrame->hide();
	}
}

To copy to clipboard, switch view to plain text mode 

and it works fine, with the "helpFrame" in the upper left corner of "frameA", but I want line 7. in terms of the "width" and "height" of frameA.
I don't want to use "spacers" or a "paint" event to get these dimensions if I can help it.

help would be most appreciated.
