ReleaseGUIObject

The functionality provided by GUIKit has been superseded by the interface construction and controls functions native to the built-in Wolfram Language.

ReleaseGUIObject[obj]

closes and terminates all resources of a live GUIObject instance.

Details and Options

  • To use ReleaseGUIObject, you first need to load GUIKit using Needs["GUIKit`"].
  • ReleaseGUIObject programmatically ends an interface's session (which is normally ended interactively by user actions such as closing the window), both closing and disposing of all related resources.
  • ReleaseGUIObject forces the termination of interface resources even if an initial GUIRun might have requested that the interface live on past its closing by using the option ReleaseMethod->Manual.
  • Use CloseGUIObject instead of ReleaseGUIObject to ensure the original life cycle intent of a GUIRun call.

Examples

Basic Examples  (1)

Wolfram Language code: Needs["GUIKit`"]

Create a live interface object:

Wolfram Language code: ref = GUILoad["Wolfram/Example/Calculator"]

Verify that the interface is active:

Wolfram Language code: GUIObjectQ[ref ]

Remove its resources:

Wolfram Language code: ReleaseGUIObject[ref ]

Confirm that the interface is no longer valid:

Wolfram Language code: GUIObjectQ[ref ]

Scope  (2)

Wolfram Language code: Needs["GUIKit`"]

Create a modeless live interface object:

Wolfram Language code: ref = GUIRun["Wolfram/Example/Calculator"]

Shut it down:

Wolfram Language code: ReleaseGUIObject[ref ]

Verify that the interface is no longer valid:

Wolfram Language code: GUIObjectQ[ref ]
Wolfram Language code: Needs["GUIKit`"]

Create a modeless live interface object, specifying a manual ReleaseMethod:

Wolfram Language code: ref = GUIRun["Wolfram/Example/Calculator", ReleaseMethod -> Manual]

Attempt to close the interface:

Wolfram Language code: CloseGUIObject[ref ]

Test whether the interface is still valid:

Wolfram Language code: GUIObjectQ[ref ]

Terminate the interface:

Wolfram Language code: ReleaseGUIObject[ref ]

Verify that it is no longer valid:

Wolfram Language code: GUIObjectQ[ref ]
