This actually is not fully true. In .NET i've used DrawCheckBox with all
possible ButtonState combination(16 for 4 bits) and , even on .NET ,
some behaviour that checkbox class has aren't reproducible with
DrawCheckBox. For example Flat and Popup have borders of different
colors. CheckBox Flat use KownColor.LightGray as checkbox background
when mouse enters control area while Popup adds a 3d shadow only when
mouse is entered leaving 2d only on MouseLeave event. I agree that i can
"simulate" almost all the states of checkbox composing ButtonState flags
in a reasonable way but the resulting appearance will be slightly
different from the .NET one.
If you think it's okey i'll finish it this way and send the .cs to you
or gopal.

I also thought that this should be the right behaviour. But i'm getting 
strange ones:

With twm it's all as it should be. Only entering in and leaving from the
control area raise MouseEnter and MouseLeave events.

With fluxbox is very strange. Right and third button(and wheel) give
correct behaviour while the left button when pushed raise also
MouseEnter and MouseLeave.

With KDE i got MouseEnter and MouseLeave events whathever button i
pushdown. 

I'm getting a fresh cvs head to check with it to exclude that i've
messed up something withouth remembering.
