Problem : Mouse Or Key events doesn't fire up?!! [SOLVED]

In order to clearly understand the way events are fired up with mogre, I tried to mix tutorials 4 & 6.

I use a windows form where i put a splitContainer:
* in panel 1, I put 2 buttons : one called 'render', another call 'stop rendering'
* in panel 2, I render the scene when the button 'render' is pressed.

The 2 buttons work fine (i can see the message box telling me if the scene is rendered or not). However the keys and mouse events programmed are never fired?? I can' understand why the camera doesn't move when keys are pressed or why the 'R' key doesn't show the message programmed????

Here is my code, if an expert can show me my mistake i will greatly appreciate,

Thx

and the program.cs reads

using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace Tuto06
{
static class Program
{
//public static mQuit = false;
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);

OgreForm form = new OgreForm();
form.Init();
form.CreateInputHandlers();
form.Show();
Application.Run();
}
}
}

have u tried calling your initialization events from inside the form ?.. like this.:



in the program.cs
..................................................................................................

using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace Tuto06
{
static class Program
{
//public static mQuit = false;
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);

OgreForm form = new OgreForm();
Application.Run();
}
}
}

...............................................................................................
you don't actually need a form.show() or less you selected a console project and then wanted to add a windows form...





and now in the FORM.cs inside the OgreForm method
...............................................................................................

public OgreForm()
{
InitializeComponent();
this.Size = new Size(800, 600);
Disposed += new EventHandler(OgreForm_Disposed);
Resize += new EventHandler(OgreForm_Resize);
Init();
CreateInputHandlers();

}
...............................................................................................

After several days of headaches, I've found the solution !!!!!!!!!

Thanks for your help marc antoine but it was more tricky than what you suggested (at least it was tricky for me!!!)

In fact, since the scene is rendered in the 2nd panel of splitContainer1, it is this object whiwh has to subscribe to the events. So the code of the CreateInputHandlers should be


public void CreateInputHandlers()
{
mRoot.FrameStarted += new FrameListener.FrameStartedHandler(FrameStarted);
this.splitContainer1.Panel2.KeyDown += new KeyEventHandler(KeyDownHandler);
this.splitContainer1.Panel2.MouseDown +=new MouseEventHandler(MouseDownHandler);
this.splitContainer1.Panel2.MouseUp += new MouseEventHandler(MouseUpHandler);
this.splitContainer1.Panel2.MouseMove +=new MouseEventHandler(MouseMoveHandler);
}


The panel object does not declare an KeyDown event (strange?!!!) so I guess it has to be implemented first, but that's an other story!

Sorry guys, but i am quite new to forums and i don't know how to mark this topic [solved] ?!!!
