Hi everyone!
I started working with edje yesterday (always a lover of e, but I was
amazed in Dave Andreoli's presentation at bossa conference!) and second
thing I wanted to do was to include a group as a swallowed object of a
part :) . I thought it was a good way to reuse the group multiple times,
and for example define a button bar and use it in multiple places, but
constrained by the swallowing part geometry.
I couldn't find how to do it using edje+embryo, but I was able to do it
using python-efl. So I wrote a patch to add a part_swallow function to
the edje exported embryo functions as a way to do this directly without
external code. Now I can do something like:
program {
name, "init";
signal, "load";
script {
part_swallow(PART:"button_bar", "Group_Button_Bar");
}
}
I don't really know if it might be useful or even if there aren't tons
of side effects, since I'm not 100% familiar with the codebase, but
maybe it is or someone can explain what's wrong and I end up learning
something!
It might be a good idea to be able to swallow another part directly
without the use of a program, which would involve changing edje syntax.
If it sounds good, I'm willing to do it.
Thanks!
Santiago.
