Refer to the previous commits for more context.
When an evas object is given to a container, be it with a variant of
efl_pack() or efl_content_set(), its "ownership" is given to the new
parent container. But ownership here means that the new container may
delete the child when it sees fit (i.e. when the container itself dies,
for instance). This does not mean that a reference was passed from the
calling context to the container. The actual EO owner of the child is
always the canvas or another canvas object, even if it the object is
unpacked.
Note: This means that invalid calls to efl_pack or efl_content_set will
not automatically delete the child object. This is the same as legacy,
and results in floating objects. Just check the return value! :)
Hopefully this is correct for bindings.
This is a new function that indicates whether an object is a child of a
parent or not. Dead simple, as this simply compares if parent == this.
Note that this check was impossible to do with the event grabber.
Also, rename group_children_iterate to group_members_iterate for
consistency with the other group_member functions.

It's not exposing anything that wasn't already accessible before (you
could just add a member and get its clip, for instance).
This will be used by Edje Object.
This is a minor
@feature
- color_set
- visible_set
- position_set
- no_render_set
- member_add, member_del
- group_add, group_del
- clip_set
Notes:
- Widget overrides color_set without calling super() which means that
color_get() returns a different value. Also any subsequent child
object add will not inherit the color.
- Smart clipped objects also don't call super.
This patch changes that, but only for smart clipped objects created
through EO. This shouldn't have any side effect.
This is really only a demonstration of what kind of information
we can print with efl_debug_name_get(). Hopefully this can help
debugging with printf/ERR logs and even help with live debugging
inside gdb.
This shouldn't be used for other purposes than debugging, as the
exact string format is not defined.
@feature
After a long search I found that fileselector was not calling
super.group_del on deletion, leading to the use of dangling pointers.
So let's verify that group_del is properly called.
See T4598
Lacking a proper internal tag, I'm using both protected (it is
in fact a protected access function) and beta (to mark as unstable,
not real API).
New smart objects based on EO only should rely on constructor,
finalize and destructor exclusively. In theory, this should be fine.
Unfortunately it may be impossible to inherit from the Efl.Ui.Win
class as it uses a really bad hack and calls super.constructor
inside the finalize method.
This is an override of efl_gfx_size_set. Same as before, the
order of operations matter so it is possible that a corner
case will break. In particular, legacy code was:
- intercept
- smart resize (do stuff), super, super, super
- evas object resize
The new code is more like:
- intercept
- super, super, super, evas object resize
- do stuff
But unfortunately this broke elm_widget (read: all widgets) as
the internal resize was done before the object resize. So,
inside the resize event cb, the resize_obj size would not match
the smart object size. >_<
This is an override of efl_gfx_position_set.
As for the other patches, I hope I didn't break anything.
A problem likely to happen is that the super call was inserted
too early or too late in the call flow. For instance:
_myclass_position_set(obj, x, y) {
position_set(super(obj), x, y);
position_get(obj, &prevx, &prevy);
do_something_with_delta_xy();
}
The above code flow is obvisouly wrong, but may have crept in this
patch (such a bug sneaked in inside smart object, breaking
everything at first).
While this kind of API seems to make sense with smart objects
(relative coordinates), it is currently not used apart from
the smart object class itself.
So, for now, I'm moving this to legacy to clean up Efl.Canvas.Group
and we can later add the equivalent in a clean "group" API.
These should be just overrides of Efl.Gfx.visible.set. Many
widgets were handling smart show() and hide() manually, which
means this patch is quite large.
Hopefully this doesn't break anything, obviously. But here are
some widgets known to be problematic, as the old code flow was
really strange (sometimes not calling the efl_super function):
- window
- notify
Similarly to group_color_set, group_clip_[un]set should not
exist and should be a result of efl_super and inheritance.
This patch also removes clip_unset from the EO API and keeps
only clip_set(NULL). The reason is that it will avoid bad overrides
of clip_unset() vs. clip_unset(NULL). This also simplifies the code
a bit. Ideally we should be able to reintroduce clip_unset in EO
if we can have a "@final" tag (like java's final keyword), to
prevent overrides.
Widgets should simply override efl_gfx_color_set and call
super all the way up to evas object.
Legacy compatibility with call interceptors and early call
abortion (eg. delete_me or obj->layer == NULL) are implemented
with an internal call. See the previous commit introducing the
API.
Most of the smart functions "Efl.Canvas.Group.group_xxx" should
not exist and be overrides of the base object function instead.
Cleaning this up is necessary if we want an EO API for custom
smart objects. This patch is the first attempt at removing a
method (the simplest one).
As for no_render, I wonder if propagating to the children
really is necessary. evas_render should skip them already.
