For some plugins it required to have GUI Mozilla calls from other threads. Common way to do that in Mozilla is interthread proxy (xpcom/proxy). Usually those calls should be on nsIPluginInstancePeer interface, but this mechanizm requires that target interface has XPT description (to generate proxy object). I've made IDL, maybe it's enough. Also all other interfaces should be IDLized. ___________________ nsIPluginInstancePeer.idl________________ #include "nsISupports.idl" #include "nsIOutputStream.idl" native nsPluginInstancePeerVariable(nsPluginInstancePeerVariable); native nsPluginMode(nsPluginMode); native nsMIMEType(nsMIMEType); %{C++ #include "nsplugindefs.h" %} [scriptable, uuid(4b7cea20-019b-11d2-815b-006008119d7a)] interface nsIPluginInstancePeer : nsISupports { [noscript] void GetValue(in nsPluginInstancePeerVariable variable, // I know it's awful in voidPtr value); [noscript] nsMIMEType GetMIMEType(); [noscript] nsPluginMode GetMode(); [noscript] nsIOutputStream NewStream(in nsMIMEType type, in string target); void ShowStatus(in string message); void SetWindowSize(in PRUint32 width, in PRUint32 height); };
