On Image #6, the instructions are -

A normal click should add a red Rectangle with width & height = 30. - A right (meta) click should add a red Oval with width & height = 30. // Try to implement right-click, but some machines won't do this properly. If this is you, just ignore this one part. - A shift-click should add a blue Rectangle with width & height = 30 - An alt-click should add a blue Oval with width & height = 30. - A control-click should clear all the Drawable shapes

But make sure that it can be called as drawingSurfacePanel somewhere.

PLS ALL CODE IN JAVA
