Hi -
GtkWidget provides API to override the background color defined in the Gtk
Theme ( gtk_widget_override_background_color ).
It doesn't seem to provide anything similar to override the background
image other than building a CSS stylesheet and using a GtkCssProvider to
load it.
Using this approach requires that the image resides somewhere in the
filesystem . If you have an image already in memory you can't use it
without first saving it out.
Another approach would be to write a custom GtkStyleProvider (similar to
the GtkModifierStyle) which provides an override background image
function. This approach seems impossible as a portion of the style
provider implementation is private (the GtkStyleProviderPrivate
interface).
Are there any other options for setting the background image on a widget
using an in-memory image?
Thanks,
Bogdan & Silenio
