* respectively) and the "object" string member for calling
* g_signal_connect_object() instead of g_signal_connect().
*
* Signals can also be directly attached to a specific state defined
* inside a #ClutterState instance, for instance:
*
* |[
* ...
* "signals" : [
* {
* "name" : "enter-event",
* "states" : "button-states",
* "target-state" : "hover"
* },
* {
* "name" : "leave-event",
* "states" : "button-states",
* "target-state" : "base"
* },
* {
* "name" : "button-press-event",
* "states" : "button-states",
* "target-state" : "active",
* },
* {
* "name" : "key-press-event",
* "states" : "button-states",
* "target-state" : "key-focus",
* "warp" : true
* }
* ],
* ...
* ]|
*
* The "states" key defines the #ClutterState instance to be used to
* resolve the "target-state" key; it can be either a script id for a
* #ClutterState built by the same #ClutterScript instance, or to a
* #ClutterState built in code and associated to the #ClutterScript
* instance through the clutter_script_add_states() function. If no
* "states" key is present, then the default #ClutterState associated to
* the #ClutterScript instance will be used; the default #ClutterState
* can be set using clutter_script_add_states() using a %NULL name. The
* "warp" key can be used to warp to a specific state instead of
* animating to it. State changes on signal emission will not affect
* the signal emission chain.
*
* Clutter reserves the following names, so classes defining properties
* through the usual GObject registration process should avoid using these
* names to avoid collisions:
