Notes on First Windows In Class

The Problem

1. Create a TWindow

   project with Draw menu. That menu has a draw circle command.

2. Add an event handler for Left button double click

   that draws a circle at the point of the click.

Selected Code

The Circle Draw

    
	 TDC *tDC = new TClientDC(*this);
	 tDC->Ellipse(20,20,150,150);
    	delete tDC;

The Double Click Handler

	 TDC *tDC = new TClientDC(*this);
	 TPoint lowerRight=point.OffsetBy(100,100);
	 TPoint upperLeft = point.OffsetBy(-100,-100);
	 tDC->Ellipse(upperLeft,lowerRight);
	 delete tDC;
