@anchor{XREFuicontextmenubusyaction}
@prindex uicontextmenu busyaction
@item @code{busyaction}: @qcode{"cancel"} | @{@qcode{"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 @code{interruptible} property set to @qcode{"off"}. The @code{busyaction} property of the interrupting callback object indicates whether the interrupting callback is queued (@qcode{"queue"} (default)) or discarded (@qcode{"cancel"}).
@xref{Callbacks, , @w{Callbacks section}}.
@anchor{XREFuicontextmenucallback}
@prindex uicontextmenu callback
@item @code{callback}: string, def. @code{[](0x0)}
A string consisting of a valid Octave expression that will be executed whenever this item is selected.
@anchor{XREFuicontextmenuinterruptible}
@prindex uicontextmenu interruptible
@item @code{interruptible}: @qcode{"off"} | @{@qcode{"on"}@}
Specify whether this object's callback functions may be interrupted by other callbacks. By default @code{interruptible} is @qcode{"on"} and callbacks that make use of @code{drawnow}, @code{figure}, @code{waitfor}, @code{getframe} or @code{pause} functions are eventually interrupted.
@xref{Callbacks, , @w{Callbacks section}}.

@anchor{XREFuicontextmenucategoryCreation/Deletion}

@table @asis
@anchor{XREFuicontextmenubeingdeleted}
@prindex uicontextmenu beingdeleted
@item @code{beingdeleted}: @{@qcode{"off"}@} | @qcode{"on"}
Property indicating that a function has initiated deletion of the object. @code{beingdeleted} is set to true until the object no longer exists.
@anchor{XREFuicontextmenucreatefcn}
@prindex uicontextmenu createfcn
@item @code{createfcn}: string | function handle, def. @code{[](0x0)}
Callback function executed immediately after uicontextmenu has been created. Function is set by using default property on root object, e.g., @code{set (groot, "defaultuicontextmenucreatefcn", 'disp ("uicontextmenu created!")')}.
For information on how to write graphics listener functions see @ref{Callbacks, , @w{Callbacks section}}.
@anchor{XREFuicontextmenudeletefcn}
@prindex uicontextmenu deletefcn
@item @code{deletefcn}: string | function handle, def. @code{[](0x0)}
Callback function executed immediately before uicontextmenu is deleted.
For information on how to write graphics listener functions see @ref{Callbacks, , @w{Callbacks section}}.

@table @asis
@anchor{XREFuicontextmenuclipping}
@prindex uicontextmenu clipping
@item @code{clipping}: @qcode{"off"} | @{@qcode{"on"}@}
If @code{clipping} is @qcode{"on"}, the uicontextmenu is clipped in its parent axes limits.
@anchor{XREFuicontextmenuvisible}
@prindex uicontextmenu visible
@item @code{visible}: @qcode{"off"} | @{@qcode{"on"}@}
If @code{visible} is @qcode{"off"}, the uicontextmenu is not rendered on screen.

@table @asis
@anchor{XREFuicontextmenubuttondownfcn}
@prindex uicontextmenu buttondownfcn
@item @code{buttondownfcn}: string | function handle, def. @code{[](0x0)}
@code{buttondownfcn} is unused.
@anchor{XREFuicontextmenucontextmenu}
@prindex uicontextmenu contextmenu
@item @code{contextmenu}: graphics handle, def. @code{[](0x0)}
Graphics handle of the uicontextmenu object that is currently associated to this uicontextmenu object.
@anchor{XREFuicontextmenuhittest}
@prindex uicontextmenu hittest
@item @code{hittest}: @qcode{"off"} | @{@qcode{"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 @qcode{"buttondownfcn"}, showing the uicontextmenu, and eventually becoming the root @qcode{"currentobject"}. This property is only relevant when the object can accept mouse clicks which is determined by the @qcode{"pickableparts"} property. @xref{XREFuicontextmenupickableparts, , @w{pickableparts property}}.
@anchor{XREFuicontextmenupickableparts}
@prindex uicontextmenu pickableparts
@item @code{pickableparts}: @qcode{"all"} | @qcode{"none"} | @{@qcode{"visible"}@}
Specify whether uicontextmenu will accept mouse clicks. By default, @code{pickableparts} is @qcode{"visible"} and only visible parts of the uicontextmenu or its children may react to mouse clicks. When @code{pickableparts} is @qcode{"all"} both visible and invisible parts (or children) may react to mouse clicks. When @code{pickableparts} is @qcode{"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 @qcode{"hittest"} property will determine how they are processed. @xref{XREFuicontextmenuhittest, , @w{hittest property}}.
@anchor{XREFuicontextmenuselected}
@prindex uicontextmenu selected
@item @code{selected}: @{@qcode{"off"}@} | @qcode{"on"}
Property indicates whether this uicontextmenu is selected.
@anchor{XREFuicontextmenuselectionhighlight}
@prindex uicontextmenu selectionhighlight
@item @code{selectionhighlight}: @qcode{"off"} | @{@qcode{"on"}@}
If @code{selectionhighlight} is @qcode{"on"}, then the uicontextmenu's selection state is visually highlighted.

@table @asis
@anchor{XREFuicontextmenutag}
@prindex uicontextmenu tag
@item @code{tag}: string, def. @qcode{""}
A user-defined string to label the graphics object.
@anchor{XREFuicontextmenutype}
@prindex uicontextmenu type
@item @code{type} (read-only): string
Class name of the graphics object. @code{type} is always @qcode{"uicontextmenu"}.
@anchor{XREFuicontextmenuuserdata}
@prindex uicontextmenu userdata
@item @code{userdata}: Any Octave data, def. @code{[](0x0)}
User-defined data to associate with the graphics object.

@prindex uicontextmenu handlevisibility
@item @code{handlevisibility}: @qcode{"callback"} | @qcode{"off"} | @{@qcode{"on"}@}
If @code{handlevisibility} is @qcode{"off"}, the uicontextmenu's handle is not visible in its parent's @qcode{"children"} property.
