Determine event name in event handler

[timmeh]

In my project I need all gui events to pass through a single handler function. This function should then determine which widget caused what sort of event and react appropriately. Is there any way to determine the event type from within an event handler? It would be very handy if EventArgs held a reference to the event name.

My interim solution is to bind the event to a general purpose handler object, like so:

Code: Select all

class evtHandler {
public:
  explicit evtHandler(Window * wnd, const CEGUI::String & evt) : m_evt(evt) {
    wnd->subscribeEvent(evt, Event::Subscriber(&evtHandler::handler, this));
  }
protected:
  bool handler(const EventArgs & args) {
    // do something useful based on args->window and m_evt
    return true;
  }
private:
  const CEGUI::String & m_evt;
};


Does anybody know of a better way to accomplish this?

Your approach looks good I think. We are not planning of adding this information into the base.
