...sulated in an 'if (dd->gettingEvent)' block. So the only times this code ever calls doKeybd() is when gettingEvent is in fact set. Further, it's called in two locations in X11_eventHelper(), in modules/X11/devX11.c, where the state of gettingEvent seems to be moot for its handling. doMouseEvent() in turn is called in HelpMouseClick(), HelpMouseMove(), and HelpMouseUp() in devWindows.c, where again each call is only made after checking if gettingEvent is true. In devX11.c it's called once in X11_eventHelper(), after checking if gettingEvent is true. Other than these calls, getting...

Hey all. As in general it's a bad idea to allow an event handler to generate an event, and as comments in the code seem to suggest this isn't the intention either, I was wondering about recursion in getGraphicsEvent(). In main/gevents.c, both doMouseEvent() and doKeybd() have the following line; dd->gettingEvent = FALSE; /* avoid recursive calls */ And they reset it to TRUE before returning. The effective result of this is that the event handlers on the R side are allowed to call getGraphicsEvent(), and recurse until they eventually woul...
