DockContent WeifenLuo Problem

Hello,
I want to create a mogre window in a weifenlou(DockPanel Suite) form.
Weifenlou is a way for special Windowsforms.

Here an example:

But when i create a mogre window in weifenlou, it is only gray.

here is the code for creating the window:

public partial class TestForm : Form
{
#region Private Member

//GfxManager
GFXManager myGFXManager;

public ITOgre test;
GFXWindow t;

#endregion

#region Public Member

/// <summary>
/// GFX Manager
/// </summary>
public GFXManager GFXManager
{
get { return myGFXManager; }
set { myGFXManager = value; }
}

#endregion

public TestFormForm()
{
InitializeComponent();

//GfxManager
myGFXManager = new GFXManager();

t = new GFXWindow();
test = myGFXManager.TOgreManager.GetNew(t, 8, "MainDevice");
}

private void TestFormForm_Shown(object sender, EventArgs e)
{


t.MdiParent = this;
t.Show(MainDockPanel);
t.DockState = DockState.Document;

}
}


GFXWindow t; Is the important window...

And here is the TOgre source:

#region Private member

private Camera myCamera;
private Root myRoot;
private SceneManager mySceneMgr;
private Viewport myViewport;

I hope some one can help me.

Check out the "tecnofreak" editor since it uses the same docking and it uses morge. I think he just recently swapped to native ogre though so you might have to get an older version from his svn

Hm, this doesn´t work, because even the last revesion of the repository countains only
the version with native ogre...

greats,
Jo0oker

you should be able to get SVN to grab an old version. I use Tortoise SVN and it's reasonably easy to get a version from the history

I also use trtoise svn and the url: https://tecnofreakanima.svn.sourceforge ... freakanima

But even when i use revesion 2, there is only the CPP version...

I've had lots of issues with DockContent and Mogre in the past. It's been a long while since that, so I don't remember perfectly, but after inspecting my code, I can tell you this.

Don't know why, but a DockContent's handle is not good for Ogre. You must create something inside the DockContent. A Panel works great. Then, you must specify the panel's Handle when creating the RenderWindow.

However, beware! That's not the only problem you're going to run into. If you're using MOIS, then it's quite possible that you have to use different handles for initialising your InputManagers and RenderWindows. Want more troubles? If you want to allow your dockContents to float around, then you'll have to deal with DockContent's madness, because it seems like when you dock/undock your windows, their Handles change!

I'm telling you, you're gonna sweat blood. Anyways, don't give up.

I'll try to have a deeper look at my code. Ask me more things if you need to.

This DEFINATELY sounds like something that should be wikied. WeifenLuo + MOIS minimal example.

That's a good idea. But I'm awfully busy lately.

I'll see if I find the time to add it to the wiki ASAP.

Anyways, you can do it yourself if you think you've got the point

Ok, i solved the problem.
I have to create the window and set the parent before creating the TOgre-Device

I really hate to resurrect a 4 year old thread, but I don't quite understand the solution to the problem here, and this thread covers it the most.
Does anyone have an example, they'd be willing to share?

I don't think anyone on this thread is still around. I'm sorry, I'm not familiar with WeifenLuo at all so I'm not sure how much help I can be. Perhaps you can try and describe the problem you're having in more detail?
