Mouse wheel events not firing

[Merad]

I'm using the .NET bindings in a C# winforms app, and actually drawing onto a panel.  Mouse clicked events work fine, but scroll events never fire.

My setup code is simply

// windowHandle is the handle of the panel we're drawing to
m_renderWindow = new RenderWindow(windowHandle,
  new ContextSettings { AntialiasingLevel = 8 });
m_renderWindow.Resized += (sender, args) => UpdateViewSize();
m_renderWindow.MouseWheelMoved +=
  (sender, args) => Log.Info("mouse scrolled");
m_renderWindow.MouseButtonPressed +=
  (sender, args) => Log.Info("mouse clicked");

My main loop calls both System.Windows.Forms.Application.DoEvents() and m_renderWindow.DispatchEvents().  And as I said, clicks work fine...

I just checked, and the event does fire correctly when I allow SFML to create the window.  So presumably the problem is with mouse events being forwarded from the winforms panel to the renderwindow.  Any ideas?

Ok, I found the solution, in case anyone else runs into this.  Windows only sends mouse wheel events to the control that has focus, but Panel is not a focusable control by default.  There doesn't seem to be a way to easily change this, so I added the following in my Form's ctor to force the panel to focus when the mouse hovers over it

drawingPanel.MouseHover += (sender, args) => drawingPanel.Focus();
