[Solved!] wxWidgets 3.0.1, ogre1.9.0 and overlays

[paulosherring]

Hello all!
I am coding a small software which the main framework is wxWidgets. Before, I used wxwidgets 2.9.4, VS2010 and ogre 1.7.2 and everything ran smooth. I went on formating my PC and decided to upgrade my IDE and whole components and now I am using VS2012, wxWidgets 3.0.1 and ogre 1.9.0. I can compile and all my previus code worked well, the only error i found was due to overlay component was moved out from ogre. Besides that, no errors on compile time.
On run time, i could not get my custom sdktrays to work (the only thing is that I striped OIS stuff and lean'd it, resuming it to params panel and other information stuff). I tried then a simple application and no sdktrays at all, only simple overlay white square and still nothing appeared.
I ask you:
Am I doing something wrong here?
Is there any know bug concerning this?

The code is bellow.
Thanks in advance!
Paulo Sherring.

As Singleton classes in Ogre need to be new'd before using, I think new Ogre::OverlayManager() or like will do the trick before you call any getSingleton() or similar function.

I tried it. I guess new Ogre::OverlaySystem(); starts all components, because when i try to instantiate another OverlayManager, with new Ogre::OverlayManager(), an exception is thrown. Likewise, if I instantiate OverlayManager and then OverlaySystem, i get an exception in the later. So, probably is not it.
Thank you, though!

I just figured it out! All I needed to do is to register OverlaySystem as a RenderQueueListener, by doing, in my case:

Code: Select all

	mOverlaySys = new Ogre::OverlaySystem();
	mSceneMgr = mRoot->createSceneManager("DefaultSceneManager");
	mSceneMgr->addRenderQueueListener(mOverlaySys);

Thanks!!
