NAME

drawCircles - A simple circle drawing program

drawCircles

Initially, the interface looks like the one given in Fig (A) with  a drawing area and  a QUIT button.  If the user clicks at position (x,y) inside the drawing area  it draws:

• A solid circle centered at  (x,y) with the largest possible radios within the drawing area.
• Two lines, one horizontal and one vertical,  intersecting at (x,y).  Each line has the largest possible length within the drawing area.


The drawing area is  always cleared before drawing  another circle and lines.

If the user clicks on the QUIT button, the QUIT button is replaced with two buttons: OK and Cancel as shown in Fig (B). During that phase, if the user clicks inside the drawing  area, the program rings a bell and does not draw as usual.
If the user clicks on the Cancel button, the program returns back  to normal operation as shown in Fig (A). If the user clicks on the OK  button, the program exits.
