Hi,

Hopefully someone can point me in the right direction here. I have added a root window and within the root window I have added a TaharezLook/FrameWindow. The position and size work but nothing else seems to have an impact on what is visible.

Here is the essential log. There are no errors.

Here is the basic code. It doesn't matter if I use a layout or in code I get the same result.

Code: Select all

    renderer = &CEGUI::OpenGL3Renderer::bootstrapSystem();
    CEGUI::SchemeManager::getSingleton().createFromFile("TaharezLook.scheme");

    //Create the root window
    //CEGUI::Window* _rootWindow = CEGUI::WindowManager::getSingleton().loadLayoutFromFile("TreeDemoTaharez.layout"); //.createWindow("DefaultWindow", "_MasterRoot");
    CEGUI::Window* _rootWindow = CEGUI::WindowManager::getSingleton().createWindow("DefaultWindow", "_MasterRoot");
    CEGUI::System::getSingleton().getDefaultGUIContext().setRootWindow(_rootWindow);

    //show window
    CEGUI::Window* _baseWindow = static_cast<CEGUI::FrameWindow*>(CEGUI::WindowManager::getSingleton().createWindow("TaharezLook/FrameWindow", "FirstWindow"));
    _baseWindow->setPosition(CEGUI::UVector2(CEGUI::UDim(0.01, 0), CEGUI::UDim(0.01, 0)));
    _baseWindow->setSize(CEGUI::USize(CEGUI::UDim(0.5, 0), CEGUI::UDim(0.5, 0)));
    _baseWindow->setText("Hello");
    _baseWindow->setProperty("CloseButtonEnabled", "True");

//    CEGUI::System::getSingleton().getDefaultGUIContext().getRootWindow()->addChild(_baseWindow);
    _rootWindow->addChild(_baseWindow);

And finally, this is what I see.

Thanks for any help.

Hmm, so far I have no specific suspicion, also I have never seen such an issue before.

Three points:
1.What is the background?
2. Do you render anything on your own ?
- if yes: can you switch all that code off so we can see if it renders correctly if you do not change anything in your opengl context? i have not yet implemented the full reset of all opengl states in the opengl renderers. it is documented though that certain states need to be set a certain way. i will try to make it better in future releases once i have time.
3. please post the full log. always the full log. thanks

You are correct. It is something I am doing in my rendering. I'll take a look at my OpenGL states and read some more documentation.

Also, I'll remember to post the full log from now on.

Thanks for your help.

*Edit: I had to set glActiveTexture(GL_TEXTURE0); at the end of my rendering loop right before rendering the GUI. Everything is good now. Thanks again!

I recommend you to change back all changed opengl states to their default values before rendering CEGUI. I do know this can be tedious but there is no real better way. Also please tell us which states you had to change, maybe we can consider them in future changes and/or someone else might be helped.

I had to set glActiveTexture(GL_TEXTURE0); at the end of my rendering loop right before rendering the GUI.

Everything else was cleaned up so that was definitely the culprit.

Thanks again!

Thanks for the info, I will keep it in mind when i will add an optional state-preserving functionality to the OGL Renderers.
