Sometimes you want to catch an action like "clicked" from elm/button
or "mouse,clicked,1" from a regular part and want to set a property
like "play" on some object. In this case there is no source property
to copy, so setting the destination makes sense. This was possible
with Embryo, and now it is with regular "program".
Sample EDC:
{{{
// test.edc, compile with edje_cc and run with edje_player
externals {
external: "elm";
}
collections {
group { name: "main";
parts {
part { name: "bg"; type: RECT;
description { state: "default" 0.0;
color: 255 255 255 255;
}
}
part { name: "button"; type: EXTERNAL;
source: "elm/button";
description { state: "default" 0.0;
rel2.relative: 1.0 0.5;
}
}
part { name: "display"; type: TEXT;
description { state: "default" 0.0;
color: 0 128 0 255;
rel1.relative: 0.0 0.5;
rel2.relative: 0.5 1.0;
text { font: "Sans"; size: 16; }
}
}
part { name: "entry"; type: EXTERNAL;
source: "elm/scrolled_entry";
description { state: "default" 0.0;
rel1.relative: 0.5 0.5;
params.bool: "editable" 0;
}
}
programs {
program {
signal: "clicked";
source: "button";
action: PARAM_SET "display" "text" "hello world!";
}
program {
signal: "clicked";
source: "button";
action: PARAM_SET "entry" "text" "bla!";
}
}
}
}
}
}}}

Choices are useful to represent enumerations and restricted set of
elements to user. Usually this is displayed in hoversel/comboboxes.

Edje got a new program action called PARAM_COPY in the form:
action: PARAM_COPY "src_part" "src_param" "dst_part" "dst_param";
This will copy the parameter "src_param" from part "src_part" to
parameter "dst_param" of part "dst_part".
So far so good, why the "crazy" in the first line? Because this also:
* do type conversion!
* set properties of native parts, not just EXTERNAL!
The type conversion allows one to get an integer and display that in a
text property, or get an string and convert into a float.
The set of native parts is quite simple, basically a map of Edje.h
edje_object_part_*_set(). With that one can set the string to be used
by a TEXT, or set drag page/step/size/value! (page/step increments are
not supported at the moment, if it is worth, they may be supported in
future).
Sample EDC:
{{{
// test.edc, compile with edje_cc and run with edje_player
externals {
external: "elm";
}
collections {
group { name: "main";
parts {
part { name: "bg"; type: RECT;
description { state: "default" 0.0;

}
}
part { name: "entry"; type: EXTERNAL;
source: "elm/scrolled_entry";
description { state: "default" 0.0;
rel2.relative: 1.0 0.5;
}
}
part { name: "display"; type: TEXT;
description { state: "default" 0.0;
color: 0 128 0 255;
rel1.relative: 0.0 0.5;
text { font: "Sans"; size: 16; }
}
}
programs {
program {
signal: "changed";
source: "entry";
action: PARAM_COPY "entry" "text" "display" "text";
}
}
}
}
}

I'm now introducing a couple of goodies to make externals more useful,
they are:
* add: extra parameter with the part name. This may be used by
external objects to emit signals in the name of that part.
* param_set/param_get: set parameters at runtime, given their names
and types. This avoids requiring users to get the actual object and
call methods. This abstraction is also good because it let one uses
Elementary without even linking to it ;-) (this have limits, like
complex types are not supported). Right now this is just exposed
to C, but goal is to have it exposed in Embryo and Lua as well.
* translate: new method to translate previously strings that are
specified statically, such as the parameters names.
Four new functions got added to the Edje API:
* edje_object_part_external_object_get() so we don't have to abuse
edje_object_part_swallow_get()
* edje_object_part_external_param_set() and
edje_object_part_external_param_get() that call the external type's
functions.
* edje_external_param_type_str() to convert types to string and
provide nicer debugs :-)
TODO:
* expose external_param_set()/external_param_get() to Embryo and Lua.

with stringshare, we can just compare pointers instead of
strcmp. Since we'll need the stringshare later, this is a good
optimization.

If file changed on disc (mtime), then make the reference dangling so
it is not reused anymore on subsequent open. If it is in cache, just
free it as it is not useful anymore.
This solves the following problem:
edje_object_file_set(ed, path, group);
ecore_file_cp(new_gen_file, path);
edje_object_file_set(ed, path, group); /* still uses the old one! */

* must disconnect connected callbacks, particularly those to
canvas. The object we previously connect will die anyway, but
canvas continues alive, dispatching its
EVAS_CALLBACK_CANVAS_FOCUS_IN and EVAS_CALLBACK_CANVAS_FOCUS_OUT,
causing nasty segmentation faults!
* must call _edje_clean_objects() *AFTER* the entry is shut
down. Otherwise ed->evas will be NULL and
evas_event_callback_del_full() will fail. I left extra checks on
those, since this call will return the given data (in our case
"ed") and NULL when callback connection was not found.
* flag existence of entries and if they were already initalized and
shutdown before, avoid redoing such work.
This fixes a stupid crash that bugged editje for a while now.

ERR() should not be used there, because _edje_lua_error() is already
an error logging function. Instead we should call eina_log_print()
directly, handling the source of the error.
SVN revision: 46058
Change group_del() to receive the name of the group to be deleted, and
change the function to not delete a group currently loaded. This causes
problems at the time of deleting the Evas_Object.
Also changed a bit the save() function and added save_all(), which saves
every group loaded, not only the one set to the object. This is mainly so
at the time of deleting a group, we can save the whole file and thus avoid
it getting out of sync with references if a group is deleted and the file
not saved afterwards.

More of this can be done, and some may even be too much, but I'm losing
perspective over it and either I'm inclined to move all of them or none
at all.
Reviews, comment, fixes and reverts are welcome.
