Drawing with Cairo: Coordinates

[Goundy]

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

Miloud B.

Maybe try changing the Image for a DrawingArea?

Evening,
Oh thank you very much Andrew, I'm trying this tonight :)
(Sorry I completely forgot that a DrawingArea widget exists)

Cheers
