direct — Use the AlphaData as indices directly into the alphamap. When
not scaled, the data are usually integer values ranging from 1 to
length(alphamap). MATLAB maps values less than 1 to the first alpha
value in the alphamap, and values greater than length(alphamap) to the
last alpha value in the alphamap. Values with a decimal portion are fixed to
the nearest, lower integer. If AlphaData is an array of uint8 integers, then
the indexing begins at 0 (i.e., MATLAB maps a value of 0 to the first alpha
value in the alphamap).
BeingDeleted on | {off} Read Only
This object is being deleted. The BeingDeleted property provides a mechanism
that you can use to determine if objects are in the process of being deleted.
MATLAB sets the BeingDeleted property to on when the object’s delete
function callback is called (see the DeleteFcn property). It remains set to on
while the delete function executes, after which the object no longer exists.
For example, an object’s delete function might call other functions that act on
a number of different objects. These functions may not need to perform actions
on objects that are going to be deleted, and therefore can check the object’s
BeingDeleted property before acting.
BusyAction cancel | {queue}
Callback routine interruption. The BusyAction property enables you to control
how MATLAB handles events that potentially interrupt executing callback
routines. If there is a callback routine executing, callback routines invoked
subsequently always attempt to interrupt it. If the Interruptible property of
the object whose callback is executing is set to on (the default), then
interruption occurs at the next point where the event queue is processed. If the
Interruptible property is off, the BusyAction property (of the object owning
the executing callback) determines how MATLAB handles the event. The
choices are
cancel — Discard the event that attempted to execute a second callback
routine.
queue — Queue the event that attempted to execute a second callback
routine until the current callback finishes.
