UnsetWidgetReference

The functionality provided by GUIKit has been superseded by the interface construction and controls functions native to the built-in Wolfram Language.

UnsetWidgetReference[name]

removes a widget from the registry with a name in the current interface.

更多信息和选项

  • To use UnsetWidgetReference, you first need to load GUIKit using Needs["GUIKit`"].
  • UnsetWidgetReference is used to remove an associated string name with a given widget within the component registry of the current script or when used with a GUIObject.

范例

基本范例  (1)

Wolfram Language code: Needs["GUIKit`"]
Wolfram Language code: ref = GUIRun[ Widget["Panel", { Widget["Label", {"text" -> "Hello World!"}, Name -> "myLabel"] } ] ]

WidgetReference allows you to use a name to access the underlying object:

Wolfram Language code: obj = ref @ WidgetReference["myLabel"]

This removes the name for the widget:

Wolfram Language code: ref@UnsetWidgetReference["myLabel"]

Now there are no named widgets:

Wolfram Language code: "WidgetNames" /. GUIInformation[ref]
