Just a blank screen

I am trying to load a simple button using the same in the wiki but all I get is a blank screen, anyone have any ideas?


void CMainMenuState::Start()
{
try
{
MyGUI::OgrePlatform* m_Platform = new MyGUI::OgrePlatform();
m_Platform->initialise(CGameManager::Instance()->GetRenderWindow());

mGUI = new MyGUI::Gui();
mGUI->initialise();

// load layout
MyGUI::LayoutManager::getInstance().load("sample.layout");
// set callback
MyGUI::ButtonPtr button = mGUI->findWidget<MyGUI::Button>("MyFirstButton");

}
catch(MyGUI::Exception& e)
{
std::cerr << e.getFullDescription() << std::endl;
}
}

void CMainMenuState::Update(f32 deltaTimeSecs)
{
mGUI->injectFrameEntered(deltaTimeSecs);
}


Here is my log, looks fine to me:

If anyone has any idea what I should look at, please tell me, I really want to figure this out, I think this is an awesome library.

Thanks,
Shane.

Whether the pointer is visible?

I don't understand, I should see a button right?

I see demos that don't work when I implement the code in my own project, is there documentation on how to use MyGUI?

update from svn abd test agian

No, I still just see a blank screen. I rebuilt the mygui engine and the orgre platform, but all I see still is a blank screen. Do we have any documentation that may list the steps I need to take in order for mygui to be implemented in a project?

I'm going through the mygui code, and looks like you removed the render window as a required parameter a few months ago. The render manager is not using it either, and the class doesn't look like it is doing much right now. I am still going through the code, but how does it know about Ogre root, the window to render to, or anything?

I am missing something, and I am sorry if this is a stupid question, but I really would like to know what I am doing wrong here.

Found the issue, I needed to create a viewport before i initialize the ogre platform.

If you want, I would like to put what I learn in the wiki if that is ok with whoever is in charge of the MyGui wiki. Let me know please so I can share what I've learned.

Thanks.

Feel free to edit wiki. And thank you for doing this.
