Good day list!
In my gtk app, I'm currently replacing deprecated GDK code with Cairo
code and I have problems with the following:
(The code is inside a timeout handler that is called repeatedly and
involves drawing part of a GDK pixmap onto a drawing area.)
/* gdk code */
gdk_draw_drawable(GDK_DRAWABLE(drawing_area->window), gc, pixmap, \
x, 0, 0, 0, drw_a_width, drw_a_height);
/* cairo code */
cr = gdk_cairo_create(GDK_DRAWABLE(drawing_area->window));
gdk_cairo_set_source_pixmap(cr, pixmap, 0, 0);
cairo_rectangle(cr, x, 0, drw_a_width, drw_a_height);
The drawing area is now showing only the pixmap background color. So,
what am I missing?
Thanks for any hints.
