[lazarus] TCanvas

[Baeseman, Cliff]

that is what may be happening with shanes code also. I was running some gdk
code against widgets last night. The calls are working not throwing errors
from gtk but they are not doing what is expected.

Shane try making that call against something like a frame or a panel. How
about running the code against the fixed widget pasted to the form.

I have been sticking with the examples under GTK, and have found some
problems with scribble-simple (section 23) that I belive are with the GDK
port to FPC.

I have placed debugging writes in pascal and printfs in C, and am getting
very different numbers.  

I was specifically looking at (PGdkEventExpose)Event^.area.height in the
expose_event function
& (PGdkEventMotion)Event^.state in motion_notify_event

I need some help beyond this point!!!
