Inheritance Hierarchy

Name Description
Selection Hierarchical location of the selected item. An empty string or array represents no selection.
SelectedData Data for the selected item, including the hierarchical location and associated data for the columns.
ColumnHeaders Array of strings in the column headers. Each string maps to the column of the same index.
Size (Inherited from GObject) Width and height in pixels of the control.
Position (Inherited from GObject) Position of the control in terms of the left and top coordinates. The left and top coordinates are relative to the parent object, such as the owning pane.
TotalBounds (Inherited from GObject) Coordinates of all sides of the control including label, caption, and other visible parts connected to the control.
Visible (Inherited from GObject) Boolean value that determines whether to display the control.
Disabled (Inherited from Control) Boolean value that determines whether the control is enabled or disabled.
Label (Inherited from Control) Reference to the label of the control.
KeyFocus (Inherited from Control) Boolean value that determines whether the control has key focus and receives the keys pressed on the keyboard.
ToolTip (Inherited from Control) Information tip of the control.
Value (Inherited from Control) Data value of this control.
ValueSignaling (Inherited from Control) Sets the data value of the control and generates an event. This property is similar to the Value property and also generates an event as if the user had interactively changed the value of the object. Use this property only when you rely on the node to generate an event in response to the programmatic value change.
