GUIObjectQ

The functionality provided by GUIKit has been superseded by the interface construction and controls functions native to the built-in Wolfram Language.

GUIObjectQ[ref]

returns True if ref is an active GUIObject and otherwise returns False.

Details and Options

  • To use GUIObjectQ, you first need to load GUIKit using Needs["GUIKit`"].
  • GUIObjectQ is used to determine whether ref represents a live interface.
  • Live interfaces are typically terminated either when the user closes the window by calling CloseGUIObject or ReleaseGUIObject.

Examples
