Here is a patch which adds the ability for elm_widgets to have a
color_class hook.
Some background:
This came about because of an app I am working on. In the app, I use
custom-themed elm_buttons (w/ elm_object_style_set). These custom-themed
buttons need the ability to change some colors such as background, etc,
etc (when certain events occur), and the elm_button does not expose it's
edje_object to allow edje_object_color_class_set calls.
So the attached patch adds the ability for an elm_widget to have a
color_class hook. When someone calls elm_object_color_class_set, the
hook will get fired and the widget can call edje_object_color_class_set
in the hook on the appropriate edje objects.
The only widget I added this for currently is elm_button (cause that's
what I needed.) If the patch goes in, feel free to add the hook for
other widgets ;)
