Figure Properties
2-784
When a handle’s visibility is restricted using callback or off, the object’s
handle does not appear in its parent’s Children property, figures do not appear
in the root’s CurrentFigure property, objects do not appear in the root’s
CallbackObject property or in the figure’s CurrentObject property, and axes
do not appear in their parent’s CurrentAxes property.
You can set the root ShowHiddenHandles property to on to make all handles
visible, regardless of their HandleVisibility settings (this does not affect the
values of the HandleVisibility properties).
Handles that are hidden are still valid. If you know an object’s handle, you can
set and get its properties, and pass it to any function that operates on handles.
HitTest {on} | off
Selectable by mouse click. HitTest determines if the figure can become the
current object (as returned by the gco command and the figure CurrentObject
property) as a result of a mouse click on the figure. If HitTest is off, clicking
the figure sets the CurrentObject to the empty matrix.
IntegerHandle {on} | off
Figure handle mode. Figure object handles are integers by default. When
creating a new figure, MATLAB uses the lowest integer that is not used by an
existing figure. If you delete a figure, its integer handle can be reused.
If you set this property to off, MATLAB assigns nonreusable real-number
handles (e.g., 67.0001221) instead of integers. This feature is designed for
dialog boxes where removing the handle from integer values reduces the
likelihood of inadvertently drawing into the dialog box.
Interruptible {on} | off
Callback routine interruption mode. The Interruptible property controls
whether a figure callback routine can be interrupted by callback routines
invoked subsequently. Only callback routines defined for the ButtonDownFcn,
KeyPressFcn, WindowButtonDownFcn, WindowButtonMotionFcn, and
WindowButtonUpFcn are affected by the Interruptible property. MATLAB
checks for events that can interrupt a callback routine only when it encounters
a drawnow, figure, getframe, or pause command in the routine. See the
BusyAction property for related information.
