Hi,
I've seen in Evas.h that most of the methods of Evas_Smart_Class are
marked as to-be-deleted in the future ("FIXME: DELETE ME"). This
concerns show(), hide(), color_set(), clip_set() and clip_unset().
I think it will be indeed a really great thing to do since when we
implement these methods for a new smart-object, we basically always do
the same thing (i.e clipping member-objects against the parent's
clipper in clip_set(), hiding the member-objects in hide_set()...). It
will also simplify a lot the code of Etk_Widget as I tried to make
these things done automatically but since Etk doesn't have access to
Evas internals, it is quite a mess.
I'm willing to try to implement those things in Evas, but first I'd
like to be sure of the behaviour to respect:
- A member-object should be "really" visible only if its parent is
visible and if it is set as visible (evas_object_visible_get() == 1).
It would remove the need for show() and hide()
- A member-object should be clipped by the intersection of its clipper
and of its parent's clipper. It would remove the need for clip_set()
and clip_unset()
- The member-objects' color should be automatically multiplied by its
parent's color at rendering (--> no more need for color_set()).
Actually, I'm not sure about this last point. What if the user would
absolutely want to have a member-object always green for example,
regardless to the color of its parent? I can see a use for this: in
estickies, the window is semi-transparent while the text is opaque,
and yet, the text is a member-object of the window.
Are you ok with this?
Do you have any other requirements for the smart-objects?
