Dear IV users,
	
	I presently have a class derived from a Glyph and Handler. 
	I redefined the draw member function in my class to Draw some 
	filled rectangles. Also whenever a DownEvent occurs I keep 
	adding filled rectangles but what is happening is although
	the new FilledRectangle is displayed properly, The old one is 
	erased. I am not sure where I am doing a mistake. 

	Any help is appreciated.

	Thanks for your time.


	My Code:

	class MyClass : public Glyph {


	void draw( .................);
	}


	MyClass::draw (.......) {

	static incr = 0;
	canvas->fill_rect (140+incr, 5, 160+incr, 10);
	incr += 25;
       }


       MyClass::DownHandle {
	   patch->redraw();
       }

       I have enclosed MyClass in a Patch and called it patch.

       DownHandle is called whenever I detect a button_down event on the Glyph.

	Though the Filled Rectangles appear on the screen. All the previous 
	ones disappear.
