This factorizes the code and makes most widgets handle key down events
in the same way:
- check that the object is not disabled, event is not on hold
- figure out the key binding based on the class name
- mark event as on hold
The class name is usually MY_CLASS_NAME but in some cases it was
MY_CLASS_NAME_LEGACY which may be different from the EO class name (eg.
elm_win vs. Efl.Ui.Win). In that case the key bindings are broken.
This breaks key bindings for the following widgets:
- Win (focus)
- Image ("clicked")
- Video (move, play)
This fixes key bindings for the following widgets:
- Nstate
Some widgets remain broken:
- Photocam / Efl.Ui.Image.Zoomable
A patch will be applied to restore the key bindings for the above
breaks.
This is an internal function that should probably become an overridable
protected method, as it's required for proper event handling in widgets.
Next step: use eo_event_info in the widgets implementations. Then remove
legacy event struct.
Ref T5363
Some names have not been changed, hopefully making a distinction
between legacy APIs and internal code (elm_layout_blah) and valid EO
usages.
This means many internal functions are still elm_layout_ as their
sole purpose is to support the legacy API.
