How to create a custom Gumball?

[mrhe (Mariusz Hermansdorfer)]

Yeah, we’re listening to keyboard events and changing functionality based on user input.

As for the code example:

Custom UI Elements with Eto.Forms

I’d start with creating basic Mouse/Keyboard events and drawing custom geometry in DrawOverlay Rhino.Display.DisplayPipeline.DrawOverlay += DisplayPipelineEvents.DrawOverlay; public static void DrawOverlay(object sender, DrawEventArgs e) { if (Display.OnScreenWidget != null) { Display.OnScreenWidget.OnDrawOverlay(e); } } public void OnDrawOverlay(DrawEventArgs e) { // your drawing code goes here e.Display.Draw... }
