[[lazarus] TCanvas]

[Michal Bukovjan]

This is what I found.
If you got the GC, you may start drawing using functions like gdk_draw_line,
etc. as defined in gdk.h, especially in gdkdraw.c.

I think the GC object has also properties like font, line style, fill style,
etc., much like windows. Functions for setting these are found in gdkgc.c.

I haven't tested this but this might provide a clue.

Also, the GtkDrawable window is a GdkWindow with some attributes set. I think
there is a macro of some sort that checks this.

So much I have learned,

Regards,

Mike
