15.3.3.12 Uicontextmenu Properties
..................................

The ‘uicontextmenu’ properties are:

‘beingdeleted’: {"off"} | "on"

‘busyaction’: "cancel" | {"queue"}
     Define how Octave handles the execution of this object’s callback
     properties when it is unable to interrupt another object’s
     executing callback.  This is only relevant when the currently
     executing callback object has its ‘interruptible’ property set to
     "off".  The ‘busyaction’ property of the interrupting callback
     object indicates whether the interrupting callback is queued
     ("queue" (default)) or discarded ("cancel").  Note:
     Callbacks section.

‘buttondownfcn’: string | function handle, def. ‘[](0x0)’
     ‘buttondownfcn’ is unused.

‘callback’: def. ‘[](0x0)’

‘children’ (read-only): vector of graphics handles, def. ‘[](0x1)’
     Graphics handles of the uicontextmenu’s children.

‘clipping’: "off" | {"on"}
     If ‘clipping’ is "on", the uicontextmenu is clipped in its parent
     axes limits.

‘createfcn’: string | function handle, def. ‘[](0x0)’
     Callback function executed immediately after uicontextmenu has been
     created.  Function is set by using default property on root object,
     e.g., ‘set (groot, "defaultuicontextmenucreatefcn", 'disp
     ("uicontextmenu created!")')’.

     For information on how to write graphics listener functions see
     Note: Callbacks section.

‘deletefcn’: string | function handle, def. ‘[](0x0)’
     Callback function executed immediately before uicontextmenu is
     deleted.

     For information on how to write graphics listener functions see
     Note: Callbacks section.

‘handlevisibility’: "callback" | "off" | {"on"}
     If ‘handlevisibility’ is "off", the uicontextmenu’s handle is not
     visible in its parent’s "children" property.

‘hittest’: "off" | {"on"}
     Specify whether uicontextmenu processes mouse events or passes them
     to ancestors of the object.  When enabled, the object may respond
     to mouse clicks by evaluating the "buttondownfcn", showing the
     uicontextmenu, and eventually becoming the root "currentobject".
     This property is only relevant when the object can accept mouse
     clicks which is determined by the "pickableparts" property.  Note:
     pickableparts property.

‘interruptible’: "off" | {"on"}
     Specify whether this object’s callback functions may be interrupted
     by other callbacks.  By default ‘interruptible’ is "on" and
     callbacks that make use of ‘drawnow’, ‘figure’, ‘waitfor’,
     ‘getframe’ or ‘pause’ functions are eventually interrupted.  Note:
     Callbacks section.

‘parent’: graphics handle
     Handle of the parent graphics object.

‘pickableparts’: "all" | "none" | {"visible"}
     Specify whether uicontextmenu will accept mouse clicks.  By
     default, ‘pickableparts’ is "visible" and only visible parts of the
     uicontextmenu or its children may react to mouse clicks.  When
     ‘pickableparts’ is "all" both visible and invisible parts (or
     children) may react to mouse clicks.  When ‘pickableparts’ is
     "none" mouse clicks on the object are ignored and transmitted to
     any objects underneath this one.  When an object is configured to
     accept mouse clicks the "hittest" property will determine how they
     are processed.  Note: hittest property.

‘position’: def. ‘[0 0]’

‘selected’: {"off"} | "on"

‘selectionhighlight’: "off" | {"on"}

‘tag’: string, def. ""
     A user-defined string to label the graphics object.

‘type’ (read-only): string
     Class name of the graphics object.  ‘type’ is always
     "uicontextmenu"

‘uicontextmenu’: graphics handle, def. ‘[](0x0)’
     Graphics handle of the uicontextmenu object that is currently
     associated to this uicontextmenu object.

‘userdata’: Any Octave data, def. ‘[](0x0)’
     User-defined data to associate with the graphics object.

‘visible’: "off" | {"on"}
     If ‘visible’ is "off", the uicontextmenu is not rendered on screen.
