Hi,
I use the following code to notify observers of custom events. I can pass
native types like booleans and strings to observers using nsISsupports***
wrappers, but how can I pass an instance of my own JS XPCOM component
(non-service) to observers?
var gObsSvc =
CC["@mozilla.org/observer-service;1"].getService(CI.nsIObserverService);
gBroadcast = function(subj, topic, data) {
var bool =
CC["@mozilla.org/supports-PRBool;1"].createInstance(CI.nsISupportsPRBool);
bool.data = subj;
var d;
if (typeof(data) == "string") {
var d =
CC["@mozilla.org/supports-string;1"].createInstance(CI.nsISupportsString);
d.data = data;
}
else {
// d is an instance of my custom JS XPCOM component. How to wrap it?
}
gObsSvc.notifyObservers(bool, topic, d);
};
// code which calls the above:
gBroadcast(true, "my-custom-event1", "foobar");
gBroadcast(false, "my-custom-event2", myCustomJSXPCOMobject);
Thanks for any suggestions,
Eric
