7 months ago I also just ran into this issue.
Steps to reproduce:
window := gui.NewWindow(200, 300)
window.SetTitle("Sub-Window")
scene.Add(window)Click on the bottom-right corner to cause the panic. Tested on Linux too, so its not just a Mac issue.
Error when clicking Label on new windows： panic: interface conversion: *core.Node is not gui.IPanel: missing method Cullable

Process finished with the exit code 2 I added the judgment and it was normal： // Move the window above everything contained in its parent if _, ok := w.Parent().(IPanel); ok { parent := w.Parent().(IPanel).GetPanel() parent.SetTopChild(w) } // If the click happened inside the draggable area, then set drag to true if w.overTop || w.overRight || w.overBottom || w.overLeft { w.drag = true Manager().SetCursorFocus(w) }
