Subject: [E-devel] [Edje]: Bug Fix: Edje draggable jumps when external
events is used.
Please find attached bug fix patch for edje draggable jump issue when
external event area is used.
Bug: When an external event area is used for edje draggable and when
after mouse move if immediate mouse down
is done then the draggable jumps back to its original position.
Analysis: In _edje_mouse_down_signal_cb When an external event area
is set i.e., when rp->events_to is set.
tmp.x value is set to 0, need_reset is set to 1 and also
_edje_recalc_do is called including emitting "drag" signal. this code
is
unnecessary/buggy and instead it causes the jump.
1. In mouse down only drag->down.x and drag->down.y needs to be set
which is being set below and tmp value need not be reset to
0 as tmp value is calculated in mouse move based on drag->down.x and
drag->down.y values.
2. need_reset is already set in mouse up hence need not be set in
mouse down again.
3. edje_recalc_do is the function which actually causes the movement
of draggable based on tmp value hence need not be called in mouse down.
because of the above code race condition happens and as tmp value is
being set to 0 and need reset is also enabled the draggable jumps back
to where it
started.
4. "drag": is sent even before "drag,start" [ should not /need not be
sent in mouse down ]
All the above code is added only when external event area is set and
the above code is not even related to whether external event is set or
not.
Solution: When an external event area is set directly equating rp =
rp->events_to and sending mouse,down would be enough, as down.x and
down.y is set below
including sending drag,start. Recalc_do should be called only in mouse
move as its responsible for movement including setting tmp value.
need_reset is already set in mouse up. drag should not be sent from
mouse down.
Change Description:
Bug Fix: Edje Draggable jumps when mouse down is done immediately
after mouse move when an external
event area is used.
demo edc pasted below to reproduce the issue.

NOTE: know issue, in elementary_config the size of the icon
change after a theme reload. I don't know what information is
lost between to reload. If someone can point at them, thanks.

(-fastcomp and -fastdecomp) -fastcomp makes for faster decompressing
AND faster compressing of edj files, -fastdecomp is a bit slower on
compression but also as fast as -fastcomp in decompression. note that
edje files built with these optiosn will not work on older edje
installations, thus they are options.

Subject: [E-devel] [PATCH][EDJE] Patch to remove the alpha from image
header while saving if the alpha is set to 1 but the image is fully
opaque
Attached to the mail is a patch to set the alpha information for an
image header to 0 with alpha present but all the texels being opaque.
Continuing to our discussion, as suggested by many people in the
community it has been implemented at edje_cc level.
Change description:
While compiling the edc file, image data for image files is
scanned to find out whether the alpha value in header is set to 1 and
is not being used in the image.
If this is the case, while writing to eet the alpha is set to 0 to
avoid blending for such images in the graphics pipeline when used by
evas.

NOTE: now you can change theme dynamically in elementary apps more reliably.
This doesn't handle the case where the swallow was done in a parent object and
the reswallow should happen in a another group. I don't how to fix that use
case.
don't see yet how to handle that

For the moment only edje_player use it. This means that when used with
edje_watch, you don't need any more to type any kind of command line
when you are testing value in your theme. As a side effect, this means
that their is a real use case to make edje_cc faster !

edje_watch call edje_cc and monitor all the source file (edc, font
image, sound). If any of them change, it call edje_cc, update its
watching list and so on. edje_watch as the same command line as
edje_cc.
Still a little bit rought, but it's the beginning of an interesting
experiment.

Subject: [E-devel] [patch] edje multisense example
Here is a try to have a working edje multisense example to fill up the
doc blank. edje-multisense.c is basically edje_example.c adapted.
I modified the edc, removing dead code, to have only a sample and a tone
example. Can be extended later.
Does the job except that it only plays sound one time per launch. Hope
someone will know why and correct it...
Attached:
- the patch for existing .edc and build system
- the new edje-multisense.c file
- duck.wav a reworked public domain wav sample of a duck quack-quack
