Subject: [E-devel] [patch] evas - add checking event type
Dear developers.
I found a bug about evas event handling.
In some situation, evas blocks some events by checking _evas_event_counter.
So I made a patch that is checking event type also event counter.
Reproduce steps:
1. make a window
2. show window before adding a elementary/genlist widget
--- codes ---
void _gl_mousedown_cb(void *data, Evas *evas, Evas_Object *obj, void *event_info)
{
printf("_gl_mousedown_cb !! \n");
}
static Eina_Bool create_main_win(App *app)
{
app->win = elm_win_add(NULL, "genlist-win", ELM_WIN_BASIC);
evas_object_show(app->win); <-- position 1
Evas_Object *genlist = elm_genlist_add(app->win);
elm_win_resize_object_add(app->win, genlist);
evas_object_event_callback_add(genlist, EVAS_CALLBACK_MOUSE_DOWN, _gl_mousedown_cb, NULL);
evas_object_show(genlist);
evas_object_resize(app->win, 320, 240);
//evas_object_show(app->win); <-- position 2
return EINA_TRUE;
}
--- codes ---
In common use case, apps don't show main window at position 1.
However to reproduce, it can be at position 1. Then, focus is at just on main window.
In that situation, if a user clicks a genlist, its event is dropped by evas.
Because in mouse down callback, it give focus to genlist.
Then two events is made. First is mouse down, second is focus handling.
In event callback, evas processes mouse down after focus handling.
But evas found that mouse event is retarded event than focus handling.
So it ignores it.
This patch is introduce event handling type checking to
evas_object_event_callback_call.

now. use old calloc+free thing for 1.0 and enable mpool for 1.1. this
is just done in advance but disabled for some testing purposes looking
for some bugs.

This commit moves Evas.h contents a lot, but it should not change code
(some conts were added, some function attributes were changed).
The purpose of such is to define the order that doxygen show modules
in its documentation.
I also splitted documentation a bit more, and added a src/examples to
list useful example code. Right now it is just a pure-evas
draw-and-save using buffer engine.
NOTE: there is lots to document, and the @todo list is quite long but
I guess lots of things there were done already. Raster, could
you review this list?

Previously, due to propagation to parent, an event could have
been received more than once by an object. This triggered
strange behaviour in edje for example where you could receive
mouse,down,1 signal many time for one swallowed object.
This patch is a fix for that problem, I hope it doesn't break
anything (e17 and elementary_test run fine here, but report
any break related to events please).

Canvas was (ab)using the same callback signature as Objects, so you
always got a confusing NULL parameter.
Just clean it up to be Evas_Object_Event_Cb and Evas_Event_Cb, each
with its own signature.

1. the concept of callbacks for a canvas as a whole. add/ del/ del_full these
2. focus in+out events for the canvas as a whole - can help solve some issues
with inoput methods + ecore-imf + entries (like edje_entry)
3. add callabcks to be called before/after flush of display.

This will check both function and data before removing the callback,
this is useful when you have lots of children monitoring parent, when
one child want to remove its monitoring function, others will remain.
Name is quite difficult to choose, I opted for "_full", but could be
"_with_data" or similar.

Evas now support objects that do not grab mouse down event (NOGRAB) aside
with the default (AUTOGRAB). API is meant to be extensible.
SVN revision: 30950
it sould be
2. fixed edje handling of delete of objects so we don't lose clip info if we
move a swallowed object out
3. fix up norender stuff for evas a bit
4. pants.
5. coogee beach (sydney) in summer right now is beatiful - KICK ASS!

parent smart object IF there is a callback set. ie. if there is a key down
callback set and propagae is set to false then the key event will not
prpagate to the parent as long as the child gets the key down events and has
the callback set.
