osg显示CEGUI界面

百度和google的好多例子都不能运行，贴一个自己试出来的。借鉴了cegui的自带例子。

#include "stdafx.h"
#include "CEGUIFirstWindow.h"
#include "CEGUI.h"
#include <CEGUIDefaultResourceProvider.h>


int main(int /*argc*/, char* /*argv*/[])
{
    // This is a basic start-up for the sample application which is
    // object orientated in nature, so we just need an instance of
    // the CEGuiSample based object and then tell that sample application
    // to run.  All of the samples will use code similar to this in the
    // main/WinMain function.
    FirstWindowSample app;
    return app.run();
}

/*************************************************************************
    Sample specific initialisation goes here.
*************************************************************************/
bool FirstWindowSample::initialiseSample()
{
    using namespace CEGUI;
//     Window* myRoot = WindowManager::getSingleton().loadWindowLayout( "test.layout" );
//     System::getSingleton().setGUISheet( myRoot );
    WindowManager& winMgr = WindowManager::getSingleton();

    // load scheme and set up defaults
    SchemeManager::getSingleton().create("TaharezLook.scheme");
    System::getSingleton().setDefaultMouseCursor("TaharezLook", "MouseArrow");
    FontManager::getSingleton().create("DejaVuSans-10.font");

    // load an image to use as a background
    ImagesetManager::getSingleton().createFromImageFile("BackgroundImage", "GPN-2000-001437.tga");

    // here we will use a StaticImage as the root, then we can use it to place a background image
    Window* background = winMgr.createWindow("TaharezLook/StaticImage", "background_wnd");
    /*********************************************************
    *                        设置地球背景
    *********************************************************/
    // set position and size
    background->setPosition(UVector2(cegui_reldim(0), cegui_reldim( 0)));
    background->setSize(UVector2(cegui_reldim(1), cegui_reldim( 1)));
    // disable frame and standard background
    background->setProperty("FrameEnabled", "false");
    background->setProperty("BackgroundEnabled", "false");
    // set the background image
    background->setProperty("Image", "set:BackgroundImage image:full_image");
    /*********************************************************
    *                        设置地球背景
    *********************************************************/
    // install this as the root GUI sheet
    System::getSingleton().setGUISheet(background);

    // load the windows for Demo7 from the layout file.
    Window* sheet = winMgr.loadWindowLayout("bar_list.layout");
    // attach this to the 'real' root
    background->addChildWindow(sheet);
}

上一张截图

代码中bar_list.layout即为自己用CEGUIEditor编辑的。

其中要注意的是layout中的每个空间的属性要代码中设置的window的属性一致，不然会出错。layout中的很多属性还是没有搞清楚。其中的是否选择全屏幕的问题。总之，好好在研究研究。
