For this patch I decided to add a pseudo legacy wrapper as the function
is called in a very large number of places. Fixing all those calls to
use the size2d form is a lot of work and a greater risk of b0rking
something.
Wherever the EO API is used, i.e. efl_add() is used to create evas
objects, we can skip the calls to set fill/expand.
This new set of defaults indeed saves ~60 loc in the tests (out of 115
objects created). I found only 3 cases where the align had to be set
manually (to the old default of 0.5).

After talking with @eunue I realised that the way I'd first
implemented the box/grid "pack" API was simply too complicated.
I had tried to make it possible to change the layout function
at runtime, like good old evas box, but since there are no function
pointers in EO the final design was really convoluted.
If someone really needs to change the layout of a box at runtime,
just create your own subclass, or unpack all items and repack them
in a new box.
Note: there are still some issues with the layout params & flow
This change lets us remove a field from the structure that leads to
around 20KiB more of saving in private dirty pages in elementary.
This also looks a bit better and feels a bit cleaner.
Breaks API and ABI.
Before this commit, function overrides were explicit. That is, you'd
have to explicitly state you were overriding a function instead of
creating a new one. This made the code a tad more complex, and was also
a bit more annoying to use. This commit removes this extra piece of
information.
This means we now store much less information per function, that will
let us further optimise out structures in the future.
It has been discussed on the ML (thread: "[RFC] rename efl_self") and
IRC, and has been decided we should rename it to this in order to avoid
confusion with the already established meaning of self which is very
similar to what we were using it for, but didn't have complete overlap.
Kudos to Marcel Hollerbach for initiating the discussion and
fighting for it until he convinced a significant mass. :)
This commit breaks API, and depending on compiler potentially ABI.
@feature
This was never used and there is no plan to ever use it. I'm going to
soon add a different mechanism with which it will be possible to provide
them again to Eo if ever needed without breaking ABI. Though it's
unlikely it will ever be.
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...
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.
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 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.
Some function names have been modified to look better in C
with the efl_content prefix.
@feature
- Children are now contents
- Efl.Pack_Layout is now a separate class and
merges Pack_Engine.
- 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, ...)
