Sets a button’s or a drop target item’s busy state. While a button or drop target is busy, it will not ac-
cept further input (e.g., SELECT-down). By default, a button or Drop Target Item will be in the busy
state while in its notify procedure and be cleared upon exiting. The busy state can be maintained after
exiting the notify procedure by setting PANEL_BUSY to TRUE from within the notify procedure. Set-
ting PANEL_BUSY back to FALSE, at a later time, clears the button’s busy state. This attribute can also
be used for similar functionality in panel item extensions.
