Handling Grip Click Events & Adding Text Input (Like Gumball)

Hello Rhino experts,

I’m developing a rhino plugin and need to implement two advanced grip behaviors:

  1. Detecting Click/Double-Click on CustomGripObject
    How can I capture when a user clicks or double-clicks on a grip?
  2. Adding a Text Input Box (Like Gumball)
    When a user clicks a grip, I want to show a textbox (similar to Gumball’s coordinate input) to let them type exact values.
  • I tried using RhinoDoc.SelectObjects += OnSelectObjects but it doesn’t trigger for grip selections
