Rotation on Qframe

[Pharell]

Take a look at QWMatrix::mapRect().

I have changed my code as follows but it doesnt work at all.

MyRect m_Dev;
       MyRect m_Form;
       QRect View = rect();
       QWMatrix m;                   
 
	int x = -( m_Dev.Left() - ((View.left() + View.right()) ) );
	int y = -( m_Dev.Top()  - ((View.top()  + View.bottom()) ) );
	m.mapRect(View); 
	m.rotate( -45.0 );

MyRect m_Dev;
       MyRect m_Form;
       QRect View = rect();
       QWMatrix m;                   

	int x = -( m_Dev.Left() - ((View.left() + View.right()) ) );
	int y = -( m_Dev.Top()  - ((View.top()  + View.bottom()) ) );
	m.mapRect(View); 
	m.rotate( -45.0 );
