[Java-gnome-developer] Drawing with Cairo: Coordinates

[Goundy <go...@gm...>]

Hi guys,

I've a quick question.
I just noticed that when drawing with cairo, in the expose event I have 
to create a context and give it the returns of source.getWindow(), this 
returns the whole application window so X and Y I set to draw my picture 
to are calculated regarding the Window and not the *drawing area* I use 
which for me is an Image.

I have an interface that contains a drawing area and lot of other staff 
on top of this area (buttons, entries,... etc), so y question is: 
There's not an easier solution to handle coordinates instead of having 
to do staff like:
draw to:
x = topButton1.x + topButton2.x + topEntry.1 + ....
y = topButton1.Y + topButton2.Y.....

?

I hope it's clear
Thank you
