Hi guys,
I'm writing some test applications to understand EFL better and check
performance on Nokia 770 and N800.
My current app is to simulate a vertical list of text items that move
on keydown "Up" or "Down". I'm using e_box as base for list and
allocating one object per item, as you recommended on a previous
thread.
Problems/Questions:
- How should I proceed to scroll it? Get the height of item, the
height of visible box and calculate e_box_align_set() vertical value,
or is there another way?
- How to make this scroll animated? I see rage-0.1 does add an
Ecore_Timer and use e_box_align_set() to move 1 row.
- Trying to be fancy I tried to add horizontal animation for items on
mouse in/out events. On mouse in I set to "selected" state, on mouse
out I set it to "default". "selected" has x=0.1, while "default" is
0.0, transition is sinusoidal. Problems are:
* I can lock up evas moving in and out fast. GDB tells me that
it's stuck in _ecore_list2_append_relative(), called from
_ecore_timer_set()... Why? Shouldn't it just work, since it's entirely
in Edje?
* When I move in (default->selected, x=0), and before transition
ends, I move out(selected->default, x=0.1), then instead of moving
back from the current point, it goes to "selected" (x=0.1) and then
start the new transition. How to avoid this behaviour and make it
smooth?
