[E-devel] ETK scrolled_view isn't draggable anymore

[John L. <joh...@op...>]

Hi list,

In the HEAD version of ETK, scrolled_view is not draggable anymore.
You can verify this by executing etk_test -> scrolled_view.  However,
the mouse event can be caught by viewport.event, which is an evas obj
on the top level.  raster added it in #34948 to add on_hold.

viewport.event is set to repeat events, but these events will
eventually be caught by something below it, maybe buttons or the
viewport itself.  So callbacks like _etk_scrolled_view_mouse_move, etc
will never be called, hence the drag function won't work.  This
behavior seems correct to me, so I wonder why the drag works in the
first place?

This could easily be worked around by set repeat mouse events to every
widgets in the scrolled_view, but there must be a better way to fix
it.  I think it might make sense to move the viewport.event to
scrolled_view, so the drag function and the on_hold function can both
work by the same top layer evas object.

I can do a patch, but I just started to learn about ETK, so I want to
ask first if I missed anything.

John
