Closing window tutorial

[bunjee]

Hey guys,

Anybody got sparing code for the Close Window procedure ?

Here is the code I'm working on:

Code: Select all

//=============================================================================
//=============================================================================

bool Gui::createWindow(const CEGUI::EventArgs& e)
{
   printf("Hello Callback\n");

   CEGUI::FrameWindow * frameWindow = CreateFrameWindow("", mRootWindow, "WindowsLook/FrameWindow");
   frameWindow->getCloseButton()->subscribeEvent(CEGUI::PushButton::EventClicked, CEGUI::Event::Subscriber(&Gui::closeWindow, this));

   CEGUI::Window * picture = CreatePicture("", "BackgroundImage", frameWindow);
   picture->setPosition(CEGUI::UVector2(cegui_reldim(0.0f), cegui_reldim(0.0f)));
   picture->setSize(CEGUI::UVector2(cegui_reldim(1.0f), cegui_reldim(1.0f)));

   return true;
}

//=============================================================================
//=============================================================================

bool Gui::closeWindow(const CEGUI::EventArgs& e)
{
   printf("Closing window\n");

   return true;
}


So far here is mine, I need to close the affiliated window in closeWindow function.

Thanks.

take a look at CEGUI::WindowManager::DestroyWindow( CEGUI::Window *)
I think it's what you're looking for.

This is a somewhat application specific question. Here are my thoughts:


1) createWindow() & destroyWindow()

The window is created entirely in code or loaded from a .layout and when you're done you remove it from the Cegui system.


2) createWindow() & setVisible(true/false)

The window is first created entirely in code or loaded from a .layout and made invisible. When you need it you make it visible and when you no longer need it you make it invisible.


The first approach uses the least amount of memory while the second approach would be the fastest at showing a window (how many miliseconds faster I cannot say).

Any way to access the component/window concerned in a callback ?
through const CEGUI::EventArgs maybe ?

try this out:

Code: Select all

bool Gui::closeWindow(const CEGUI::EventArgs& e)
{

   const CEGUI::WindowEventArgs& we =
      static_cast<const CEGUI::WindowEventArgs&>(e);

   CEGUI::String senderID = we.window->getName();

   printf("Closing window %s\n", senderID.c_str());

   return true;
}


the window is stored in we.window.
