this should be "the actor that emitted the signal"; copy and paste on docs should be disabled by default. :-/ > Now I've taken this to mean that 'actor' is the actor which originally > received the event, for instance, a button inside of a container. > However it appears to be the actor the event has been captured by. yes, for obvious reasons we cannot emit signals on actors that did not receive the event. > This leaves no way to determine what has received the event within the > captured event call back. clutter_event_get_source(). > Is this the correct behaviour, or am I correct in assuming that I should > be receiving the actor for which the event would have been received by > if it weren't for capturing it. the ::captured-event signal works exactly like the ::event signal, which has the same semantics used by gtk+, only it works from the top-most container to the actor. the event is propagated, in case of the ::event signal, from the reactive actor that received the event from the windowing system (as determined by the pick) to its parents until it reaches the stage; the ::captured-event signal is emitted before the ::event signal and is emitted on the stage that contains the actor and down through the actor's parents until it reaches the actor itself. ciao, Emmanuele. -- Emmanuele Bassi, Senior Engineer | emmanuele.ba...@intel.com Intel Open Source Technology Center | http://oss.intel.com -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com
