Hi all,

I have a window that I attach a hidden event in runtime. This is the code I use for adding removing the event:


template <class _T>
      void SetResultCallback(bool (_T::*function)(const EventArgs&), _T* pObj)
      {
         this->m_pWindow->subscribeEvent (CEGUI::FrameWindow::EventHidden, Event::Subscriber(function,pObj));
      }

void CYesNoDialog::RemoveResultCallback()
{
   this->m_pWindow->removeEvent(CEGUI::FrameWindow::EventHidden);
}

The problem is the following: I can attach a handler without problem and it works ok, but when I call RemoveResultCallback(), and later on I call m_pWindow->hide() wich trows an exception (This m_pWindow is the window I added and removed a handler for the hidden event) saying:

Expresion: map/set iterator not incrementable.

I can guess what's hapenning, but don´t know how to fix it, or if I´m not removing the event correctly.

Can anyone help here?

Thanks in advance,
HexDUmp.

Hi,

That is not the correct way to unsubscribe from an event

What you're actually doing is completely removing the event object from the window.

When you subscribe you get returned a connection object, you can (and should!) use this to unsubscribe...

Code: Select all

...
using namespace CEGUI;

Event::Connection con = myButton->subscribeEvent("Clicked", &myHandler);
...
// some time later
...
con.disconnect();
...

I hope this gives you the idea

CE.
