System::injectMouseButtonUp() crashes when deleting GUI

[some_name]

I have a button in a window which, when clicked, causes state to change, which causes the current GUI to be disposed and the GUI sheet reset to NULL. This causes the function injectMouseButtonUp() to crash sometime after the event has been dispatched and my action taken.

Is this a known bug? The documentation for the injection functions say nothing about it not being OK to change the GUI configuration inside any callbacks/events.

Hi,

is that the injectMouseButtonUp which creates the click, or a new one? I hope this question is clear. Because a click 'ends' an event, so you should be able to cleanup windows, even the clicked one. Maybe you can post some code?

It is the inject that creates the HandleClicked callback.

The code looks something like the below.

Creation:

Code: Select all

  window_ = CEGUI::WindowManager::getSingleton().loadWindowLayout(
      (CEGUI::utf8*)layout);
  BuildWidgetList(window_);


void MyClass::BuildWidgetList(CEGUI::Window *window) {
  if (window->getType() == "TaharezLook/Button") {
    CEGUI::Event::Connection conn = window->subscribeEvent(
        CEGUI::PushButton::EventClicked,
        CEGUI::Event::Subscriber(&MyClass::HandleClicked, this));
    connections_[window->getName()] = conn;
  }
  widgets_[window->getName()] = window;
  for (size_t cnt = window->getChildCount(), i = 0; i < cnt; ++i) {
    BuildWidgetList(window->getChildAtIdx(i));
  }
}

  mGUISystem->setGUISheet(window_);
  gApplication->SetBuffered(true); // turns on event injection



Handling/destruction:

Code: Select all


bool MyClass::HandleClicked(CEGUI::EventArgs const &e) {
  delete window_;
  gApplication->SetBuffered(false);
  mGUISystem->setGUISheet(0);
  return true;
}



As far as I can tell, this is all kosher (except, possibly, for the call to setGUISheet(0)).

I'm still trying to make this work without crashing, so any pointers on what I'm trying to do would be helpful.
