CEGUI - Trouble loading xml layout files.

Hi, I just recently started messing with the CEGUI. I'm trying to load in an xml layout file, however when I run the program it crashes and I get this error:

Unhandled exception at 0x766142eb in GUI_Test.exe: Microsoft C++ exception: CEGUI::InvalidRequestException at memory location 0x0012d238..

This is my code:



#include "ExampleApplication.h"
#include <CEGUI/CEGUI.h>
#include <OIS/OIS.h>
#include <OgreCEGUIRenderer.h>


// Both OIS & CEGUI use same key codes for keyboard input. Same is not true for mouse.
// Fucntion converts OIS button IDs into CEGUI button IDs.
CEGUI::MouseButton convertButton(OIS::MouseButtonID buttonID)
{
switch (buttonID)
{
case OIS::MB_Left:
return CEGUI::LeftButton;

case OIS::MB_Right:
return CEGUI::RightButton;

case OIS::MB_Middle:
return CEGUI::MiddleButton;

default:
return CEGUI::LeftButton;
}
}


class TutorialListener : public ExampleFrameListener, public OIS::MouseListener, public OIS::KeyListener
{
public:
TutorialListener(RenderWindow* win, Camera* cam)
: ExampleFrameListener(win, cam, true, true)
{
mContinue=true;
mMouse->setEventCallback(this);
mKeyboard->setEventCallback(this);
} // CEGUIDemoListener

bool frameStarted(const FrameEvent &evt)
{
mKeyboard->capture();
mMouse->capture();

return mContinue && !mKeyboard->isKeyDown(OIS::KC_ESCAPE);
}

bool quit(const CEGUI::EventArgs &e)
{
mContinue = false;
return true;
}

// MouseListener
bool mouseMoved(const OIS::MouseEvent &arg)
{
// injectMouseMove function expects relative mouse movements. OIS::mouseMoved
// handler gives us those relative movements in state.X.rel & state.Y.rel variables.
CEGUI::System::getSingleton().injectMouseMove(arg.state.X.rel, arg.state.Y.rel);
return true;
}

bool mousePressed(const OIS::MouseEvent &arg, OIS::MouseButtonID id)
{
// Convert the button ID which was passed in, and pass result to CEGUI.
CEGUI::System::getSingleton().injectMouseButtonDown(convertButton(id));
return true;
}

bool mouseReleased(const OIS::MouseEvent &arg, OIS::MouseButtonID id)
{
CEGUI::System::getSingleton().injectMouseButtonUp(convertButton(id));
return true;
}

// KeyListener
bool keyPressed(const OIS::KeyEvent &arg)
{
// After getting system object, we first need to inject the key down event to CEGUI.
// Then we inject the actual character that was pressed; inorder to obtain desired
// result, even with non-english keyboards.
CEGUI::System *sys = CEGUI::System::getSingletonPtr();
sys->injectKeyDown(arg.key);
sys->injectChar(arg.text);
return true;
}

bool keyReleased(const OIS::KeyEvent &arg)
{
CEGUI::System::getSingleton().injectKeyUp(arg.key);
return true;
}

private:
bool mContinue;
};

The file is saved in the correct directory, so I am not sure what the problem is. Any help would be much appreciated.

Hi,

Wrong forum unfortunately, this forum is for Python-Ogre, you're unlikely to get any help with c++ issues here ( mainly because most of us dont even use c++ )

theres also the cegui addon forum, i guess you meant to post in that

Sorry about that.
