wxOgre? Ogre in a wxWidget frame?

[Blackbeard]

Hi,
i want to port my Mogre project to Ogre 1.6 and C++.
As GUI for my tools i want to use wxWidget, but its hart to get started.
How to make Ogre render in a wxWidget Window (frame)?

Theres a tutorial telling you how to get wxWidget's and Ogre 1.2 to work.
Is that tutorial outdated or does it work for Ogre1.6 too?

In Mogre basicly all i have to do is to give the control handle to Ogre as string.
misc["externalWindowHandle"] = Handle.ToString();

How does it work with wxWidgets?
Any other examples around which could tell me how to render in a wxWidget frame?

Any help or clues of how to get started would be more then welcome

There is nothing about Ogre that has changed the way you embed it in any window, wxWidgets included.

You don't need "wxOgre" or anything special -- you get the window handle the same way in wx as you do in Mogre, it's a method:

Code: Select all

/*****************************************************************************/

void ColladaViewerFrame::initGfx()
{
	m_pRoot = new Ogre::Root("", "");
#if defined(_DEBUG)
	m_pRoot->loadPlugin("RenderSystem_Direct3D9_D");
	m_pRoot->loadPlugin("Plugin_OctreeSceneManager_D");
	m_pRoot->loadPlugin("Plugin_CgProgramManager_D");
#else
	m_pRoot->loadPlugin("RenderSystem_Direct3D9");
	m_pRoot->loadPlugin("Plugin_OctreeSceneManager");
	m_pRoot->loadPlugin("Plugin_CgProgramManager");
#endif // _DEBUG

	m_pRoot->setRenderSystem((*m_pRoot->getAvailableRenderers())[0]);
	m_pRoot->initialise(false);

	Ogre::NameValuePairList params;
	params["externalWindowHandle"] = Ogre::StringConverter::toString( (unsigned long)GetHwnd() );

	m_pWindow = m_pRoot->createRenderWindow(m_title, GetSize().GetWidth(), GetSize().GetHeight(), false, &params);
	m_pSceneMgr = m_pRoot->createSceneManager("OctreeSceneManager");
	m_pRayQuery = m_pSceneMgr->createRayQuery(Ogre::Ray());
	m_pWindow->setActive(true);
}

I would start with a basic wx "hello world" program, and the rest of your questions should answer themselves.

It may be a complex example but, in Addons forum we have a project called ogitor, the source is available and it has BOTH MFC and wxWidgets versions which you can check (for wxOgitor, check renderpanel.h/cpp)

Right, so it is.
But define GetHwnd() - it's slightly different across various windowing frameworks.

This is from the Project Wish wiki - a useful wxWidgets/Ogre snippet:
http://wiki.projectwish.com/index.php?t ... ts_Control
And, Xavier is right: Nothing about Ogre has changed regarding setting the window handle.

Nice, thank you, thats a start

Hi, I found the learning curve for wxWidgets quite steep myself, mainly due to conventions that I was just not used to.

This was useful for getting started with wxWidgets as it worked almost out of the box (I had some issues with the preprocessor and wxWidgets).

FYI there is source for Ogre 1.01, 1.2, 1.4 and the above link on the wiki. I have some more wxWidgets links at home that I will post later.

Thanks guys, its working so far:D
Setting up wxWidget was an adventure itself. Quiet easy once you have done it the first time.

MVS C++ Express + wxWidget 2.8.10
That cool guy here shows you how to setup it:

Think i will use DevC++ IDE as Widget Designer (sucks a little, but it doesnt seem that there is any other free designer around?).

I use wxFormBuilder - it's by far the best, IMO. Payed for or free.

wxSmith inside Codeblocks has so many widgets in the Gui-builder that cant even compare to wxFormBuilder. wxSmith is very stable too

It seems that I have a good chances to get answer from gurus for this question: "why is externalWindowHandle deprecated?" See this post.
