MyGUI 3 do not shutdown correctly?

Hi

I have written an application that allows the user to change the video modes during runtime. In order for this to happen I have to shutdown everything, including MyGUI and Ogre and restart Ogre and MyGUI.

However after I started MyGUI for the second time, the very first widget I create does not display, but the rest does. This only happens after the second startup of MyGUI even though I run exactly the same code to create the GUI. This leads me to the conclusion that either I did not shutdown/destroy something I was suppose to or I have discovered a leak/bug in MyGUI.

To shutdown MyGUI, I did:



MyGUI::OgrePlatform* ogre_platform;

MyGUI::GUI* mygui;



// ...

mygui->destroyAllChildWidget();

mygui->shutdown();

delete mygui;

mygui = 0;



ogre_platform->shutdown();

delete ogre_platform;

ogre_platform = 0;

And to shutdown OGRE:



Ogre::Root* ogre;

Ogre::SceneManager* scene;

Ogre::RenderWindow* window;

// ...



scene->destroyAllCameras();

scene->clearScene();



window->removeAllViewports();

window->destroy();

window = 0;



delete ogre;

ogre = 0;

I'm using Ogre 1.7 and MyGUI 3.0.1

I have exactly the same problem, any hints ?

I can confirm it happens on both Linux and Windows.

Show your init/deinit code. In the code above OgrePlatform wasn't de-initialised.

// Init MyGUI

mGuiPlatform = new MyGUI::OgrePlatform();

mGuiPlatform->initialise(window->getRenderWindow(), mGuiSceneManager, SCREEN_RESOURCE_GROUP);

mGuiPlatform->getRenderManagerPtr()->setActiveViewport(window->getGuiViewPortIndex());

mGui = new MyGUI::Gui();

mGui->initialise("core.xml");



// Destroy gui

mGui->shutdown();

delete mGui;

mGuiPlatform->shutdown();

delete mGuiPlatform;

Did I forget to de-initialise OgrePlatform too ? How do I do that ?
