Hi ppl, fine?  I'm trying to draw rectangles like this:   I'm trying to draw rectangles on my screen the same way I draw rectangles in paint! I click somewhere and drag the mouse to another place, and the rectangle will be drawn!  how can I do this?   I tried it with graphics, but I could not  and I would like to draw them on my screen, not in a GUI...   if someone can help me, i'll be very grateful!
