efl_ui_win: make win work for evas_norender
Needs ReviewPublic

Authored by kimcinoo on Thu, Dec 6, 2:59 AM.



The evas_norender updates the canvas internal objects.
But efl_ui_win does not evaluate its internal objects, when evas_norender is
called before showing, after resizing as below.

evas_object_resize(win, 300, 600);

This problem could be verified by checking if a resize function of internal
object is called or not.

minw,h is 0 in _elm_win_resize_objects_eval but deferred_resize_job is TRUE.

evas_norender -> _window_layout_stack ->  _elm_win_resize_objects_eval

So if _elm_win_resize_objects_eval does not return if deferred_resize_job is
TRUE even if minw,h is 0, and calls _elm_win_resize_job, then it will work.

_elm_win_resize_objects_eval -> _elm_win_resize_job ->
evas_object_geometry_set  -> _efl_canvas_group_group_need_recalculate_set ->
_window_layout_stack -> evas_object_geometry_set -> resize function.

I have checked this behavior without elementary. It seems that evas_norender
works between resize and show in this case. Let me share examples.

ecore_evas_resize(ee, 100, 100);
Test Plan

Use examples and set break point to resize function (ex: _sc_resize).
Check backtrace starts from evas_norender.

What was this test (!minw && !minh) originally for? Existing code, like elementary_test, gets here with sd->deferred_resize_job TRUE and minw, minh == 0

It's not immediately obvious to me what impact the change has there, but it seems like this may be an unwanted side effect?
