When this was renamed from elm_flip to efl_ui_flip the _eo.h header was lost
which is needed as redirection. This broke for me in distcheck when the .eo.h
was going to get generated. It also aligns it with the other headers we have
here.
This allows apps to set the objects min size with hint_min,
while letting the rest of EFL define the minimum size with
rstricted_min.
I don't like the property names much...

Elm.Interface.Fileselector now supports Efl.Model objects, allowing users
to work with paths from different data models.
Example of model attribution:
ELm_Fileselector *fs = eo_add(EFL_FILESELECTOR_CLASS, NULL);
Efl_Model *model = ...;
elm_interface_fileselector_model_set(fs, model, NULL);
Now when dealing with pointer types, we will not get pointer to
pointer semantics in callbacks and eina_promise_owner_value_set
for Eina_Promise.
It will work as expected:
Eina_Promise_Owner* promise = eina_promise_add();
void* p = malloc(sizeof(T));
eina_promise_owner_value_set(promise, p, &free);
This does:
1. Forward keyboard events from evas to win
2. Allow feeding external input events
Input events can be faked by apps by simply forging
eo objects of the proper type (key or pointer evt) and
calling eo_event_callback_call().
Such events will be forwarded to the internal Evas, and
some bool flags prevent infinite refeeding loops.
efl_event_dup() returns fake events for this to work.
@feature
This reverts commit ac5a0b7e79.
I added assert(pd == sd) in the modified code and couldn't find

I also can't find a crash or a bug currently in hover. I know there

We can not assume that the elementary parent will be also somewhere in the eo parent
hierarchy. We need to explore both when doing an eo_provider_find in elementary for it
to be really useful.
This lets me narrow down the remaining cases of pointers across the EFL.
The void pointers will later need to be reevaluated on per-case basis and
replaced appropriately where possible/feasible.
1. remain elm_win_type_set
2. remain elm_win_alpha_set
3. remain elm_win_available_profile_set/get
app usually set availble profile into window, and app fw or other lib can read it.
so I remain get/set api both.
4. remove elm_win_profile_set/get from eo
5. remove illume feture in eo and move it to legacy
This code was written when eo_del() was removed and eo_unref() was the
recommended practice. Since we added eo_del() back we now need to adjust
this new code accordingly.
This reverts commit 546ff7bbba.
It seems that eo_del() is useful and removing it was creating bugs.
The issue is that the way we defined parents in eo, both the parent and
the programmer share a reference to the object. When we eo_unref() that
reference as the programmer, eo has no way to know it's this specific
reference we are freeing, and not a general one, so in some
circumstances, for example:
eo_ref(child);
eo_unref(child); // trying to delete here
eo_unref(container); // container is deleted here
eo_unref(child); // child already has 0 refs before this point.
We would have an issue with references and objects being freed too soon
and in general, issue with the references.
Having eo_del() solves that, because this one explicitly unparents if
there is a parent, meaning the reference ownership is explicitly taken
by the programmer.
eo_del() is essentially a convenience function around "check if has
parent, and if so unparent, otherwise, unref". Which should be used when
you want to delete an object although it has a parent, and is equivalent
to eo_unref() when it doesn't have one.
1. remain borderless property.
2. shaped property was removed because wayland not support this.
3. remain noblank property.
4. remain role, name properties.
5. remove title property because it can be supported using name property
1. remain iconified, maximized, fullscreen property
2. remain sticky property
3. change return value type of modal from bool to enum for the future.
4. merge urgent_set and demand_attention
5. remain activate method
1. remain focus_highlight_style,focus_highlight_enabled,
focus_highlight_animated,prop_focus_skip,focus. because each window need to set the focus
feature.
2. autohide, autodel is remained for convenient.
3. icon_name will be removed. elm_win_icon_object_get can used instaed of icon_name.
elm_win have three feature releated with screen.
1. screen_rotation_get
2. scrren_size_get
3. screen_dpi_get
so create efl_screen interface, and elm_win implement that interface
Summary:
- elm_map has a scrollbale interface and it is set
as ELM_SCROLLER_SINGLE_DIRECTION_SOFT by default.
- elm_map can be rotated by gesture or by an API
elm_map_rotate_set, so this single direction
makes scroll unnatural.

This is going back to the same idea as legacy. We will have
events such as:
- move
- down
- up
- in
- out
- wheel
- cancel ("new" - very rare)
Now the question is whether/how we should divide "multi" events
which start from the 2nd finger from standard mouse events. The first
multitouch finger should by default look like a mouse event.
This moves Efl.Pointer.Event back to Evas. Originally I wanted
to share this class with Ecore but eventually I didn't need to
do so, since only ecore_evas (which depends on evas) really needs
access to these.
The internal data struct is not moved out of efl (yet?)
previously, elm_image refered to align values
set by evas_object_size_hint_align_set function
to position the internal image inside an image object.
size hint value is for positioning the image object inside its container object,
so the previous code is inappropriate.
this commit adds 'align' property for positioning the internal image.

Previously, preserved content was shown unexpectedly after its naviframe
item was popped because the preserved content was not removed but was
unset from its naviframe item.
Since popped naviframe item becomes hidden on the screen, the preserved
content of the popped naviframe item should become hidden by default as
well.

Efl.Part uses a basic inheritance for layout objects, but somehow
this completely falls apart when the child class overrides all
the functions. Weird. I'll check that more.
Summary:
When the widget is unset from any container, a parent of the widget
doesn't exist. So we should set its parent to the top object.
But if we just set sd->parent, the parent can not find the widget as a
child. So the container widgets set the parent-child relation when
sub object is unset.

Previously events used to use class name as a prefix and ignored eo_prefix
when specified. This is no longer the case. Events follow eo_prefix by default
now. In order to get around this for classes where this is undesirable, a new
field event_prefix was added which takes priority over eo_prefix. If neither

We used to have eo_del() as the mirrored action to eo_add(). No longer,
now you just always eo_unref() to delete an object. This change makes it
so the reference of the parent is shared with the reference the
programmer has. So eo_parent_set(obj, NULL) can free an object, and so
does eo_unref() (even if there is a parent).
This means Eo no longer complains if you have a parent during deletion.

This renames some APIs from Efl.Pack in order to try and
make them more sensible. Feedback welcome.
Also, most APIs now return bool, where false is quite unlikely
to happen.
This moves the part_box and part_table APIs to a fake object
like was done in Edje Object.
This also adds support a few new APIs to those containers,
so they behave exactly like Edje.Object.
This is another implementation bit of "eo_part".
This removes Efl.Pack_Named which had a terrible name,
removes Elm.Container which should have been renamed
Efl.Ui.Container anyway, and introduces an interface
Efl.Container instead.
The hierarchy tree is now changed as objects don't inherit
from Efl.Container (it's an interface, not a regular class)
but only implement it. Obviously it is very easy to
reintroduce an Efl.Ui.Container parent class if we need it,
but I guess it should have some actual logic. It's basically
part of what Elm.Widget already does.

- Children are now contents
- Efl.Pack_Layout is now a separate class and

- Removed dumb class Efl.Pack_Item
- Updated docs
- Added pack_ or grid_ prefixes to some methods
Untested yet. Will need to add the common 3 classes:
- standard
- homogenous
- homogenous max_size
And then implement a true custom layout function, that
respects weights in a certain manner (need to define it
clearly).
This fixes the linear API usage with a table.
TODO:
- remove internal table (as it doesn't support layout funcs)
- implement multiple layout functions (regular, homogenous, ...)
This reuses the Evas.Box code, since we are still using the
box internally. The flow layout function is far from perfect
(it works well only with items of same height).
This shows how to use specific layouts provided by EFL.
So, since we don't have function pointers, all the solutions
to reimplementing the layout function are quite convoluted:
1. use events
2. reimplement layout func
3. use an extra object
4. use a generic class (non instanciated)
Promises don't apply here (layout will run multiple times).
Problems:
1. Multiple event callbacks will be called, resulting in
potential performance impact, extra events, etc...
Also, there is no way to define standard implementations
that would be provided by the framework.
2. Reimplementation of a function requires extra EO work
(create an EO class, etc...), doesn't allow on-the-fly
change of the layout method.
3. Probably the best solution is to have an object implementing
the layout. But this means creating an extra object along
with the container.
4. To avoid the extra object, use a class, and reimplement
a @class function. This unfortunately requires extra
EO work.
Solution 4. has been selected, but it's not very nice...
This is only a partial implementation, work in progress.
The grid object should be a replacement for evas and elementary's
table and grid. Only the layout of items inside the container
is different, otherwise the API should be the same.
For now, this widget is based on an evas table but the full
layout logic will need to be reimplemented, eventually.

This should be the only linear packing container.
This replaces: evas box and elm box.
Edje box needs to be kept around for compatibility,
but it stays an EDC object only (for apps).
Lots of things are still to be fleshed out in this
box implementation:
- Simplify smart object / elm widget code
- Maybe stop using evas object box altogether
- Implement other layout strategies
