|
|
* a given Edje object.
|
|
*
|
|
* @param obj A handle to an Edje object
|
|
* @param emission The signal's "emission" string
|
|
* @param source The signal's "source" string
|

|

|
|
*
|
|
* Edje signals are one of the communication interfaces between
|
|
* @b code and a given Edje object's @b theme. With signals, one can
|
|
* communicate two string values at a time, which are:
|
|
* - "emission" value: the name of the signal, in general
|
|
* - "source" value: a name for the signal's context, in general
|
|
*
|
|
* Though there are those common uses for the two strings, one is free
|
|
* to use them however they like.
|
|
*
|
|
* This function adds a callback function to a signal emitted by @a obj, to
|
|
* be issued every time an EDC program like the following
|
|
* @code
|
|
* program {
|
|
* name: "emit_example";
|
|
* action: SIGNAL_EMIT "a_signal" "a_source";
|
|
* }
|
|
* @endcode
|
|
* is run, if @p emission and @p source are given those same values,
|
|
* here.
|
|
*
|
|
* Signal callback registration is powerful, in the way that @b blobs
|
|
* may be used to match <b>multiple signals at once</b>. All the @c
|
|
* "*?[\" set of @c fnmatch() operators can be used, both for @p
|
|
* emission and @p source.
|
|
*
|
|
* Edje has @b internal signals it will emit, automatically, on
|
|
* various actions taking place on group parts. For example, the mouse
|
|
* cursor being moved, pressed, released, etc., over a given part's
|
|
* area, all generate individual signals.
|
|
*
|
|
* By using something like
|
|
* @code
|
|
* edje_object_signal_callback_add(obj, "mouse,down,*", "button.*",
|
|
* signal_cb, NULL);
|
|
* @endcode
|
|
* being @c "button.*" the pattern for the names of parts implementing
|
|
* buttons on an interface, you'd be registering for notifications on
|
|
* events of mouse buttons being pressed down on either of those parts
|
|
* (those events all have the @c "mouse,down," common prefix on their
|
|
* names, with a suffix giving the button number). The actual emission
|
|
* and source strings of an event will be passed in as the @a emission
|
|
* and @a source parameters of the callback function (e.g. @c
|
|
* "mouse,down,2" and @c "button.close"), for each of those events.
