Hi Eduardo,
At the GTK-server website you can find two examples on how to do it.
These are:
http://www.gtk-server.org/canvas.lsp
http://www.gtk-server.org/fractal.lsp
(Indeed these examples cannot be found at my newLisp website.) The last example
is most easy to read, I think.
Anyway, in these programs you can see how it works. In short, the code looks
like this:
# Put some text on the canvas
(set 'LAYOUT (gtk_widget_create_pango_layout IMAGE {"Some text"}))
(gdk_draw_layout PIX GC 130 240 LAYOUT)
The variable 'IMAGE' points to a gtk_image, the variable 'PIX' to a gdk_pixmap,
and the variable 'GC' points to a gdk_gc.
Please refer to the Pango documentation for details on font size, type, and so
on. Of course additional Pango-functions must be added to the GTK-server
configfile first, before they can be used.
Hope this helps.
Regards
Peter
