Activates or inhibits user interaction.
"YES" (active), "NO" (inactive).
Default: "YES"
An interface element is only active if its native parent is also active.
ACTIVE can also be set for controls that do not have user interaction because they may have a visual feedback to indicate the inactive state.
In GTK and Motif the inactive dialogs will still be able to move, resize and change their Z-order. Although their contents will be inactive, keyboard will be disabled, and they can not be closed from the close box.
All controls that have visual representation.
