This is basically how my wxGLCanvas wrapper does it:

1. Extend the base type

  
        Type TCanvas Extends wxGLCanvas

2. Connect up the events you want to see in OnInit()

	Connect(Id,wxEVT_MOTION, _OnMouseMove)
			
	Connect(Id,wxEVT_LEFT_DCLICK, _OnMouseDown)
	Connect(Id,wxEVT_LEFT_DOWN, _OnMouseDown)
	Connect(Id,wxEVT_RIGHT_DOWN, _OnMouseDown)
	Connect(Id,wxEVT_MIDDLE_DOWN, _OnMouseDown)
			
	Connect(Id,wxEVT_LEFT_UP, _OnMouseUp)
	Connect(Id,wxEVT_RIGHT_UP, _OnMouseUp)
	Connect(Id,wxEVT_MIDDLE_UP, _OnMouseUp)
	Connect(Id,wxEVT_MOUSEWHEEL, _OnMouseWheel)

Where Id is the ID you used to create the Gadget ie... GetID()

3. Create your MouseDown/Up etc functions

	Function _OnMouseDown(_event:wxEvent)
		TCanvas(_event.parent).OnMouseDown(wxMouseEvent(_event))
	End Function
	Function _OnMouseMove(_event:wxEvent)
		TCanvas(_event.parent).OnMouseMove(wxMouseEvent(_event))
	End Function
	Function _OnMouseUp(_event:wxEvent)
		TCanvas(_event.parent).OnMouseUp(wxMouseEvent(_event))
	End Function

4. And your Methods:

	Method OnMouseDown(_event:wxMouseEvent)
                Local button:Int = _event.GetButton()
                ' Your custom code here	
                _event.Skip()
        End Method
	Method OnMouseMove(_event:wxMouseEvent)
                Local x:Int = _event.GetX()
                Local y:Int = _event.GetY()
                ' Your custom code here	
                _event.Skip()
        End Method
	Method OnMouseUp(_event:wxMouseEvent)
                Local button:Int = _event.GetButton()	
                ' Your custom code here	
                _event.Skip()
        End Method

Here is a decent place to start...
