@table @asis

@anchor{XREFuimenubusyaction}
@prindex uimenu 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{XREFuimenuinterruptible}
@prindex uimenu 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{XREFuimenumenuselectedfcn}
@prindex uimenu menuselectedfcn
@item @code{menuselectedfcn}: string | function handle, def. @code{[](0x0)}

@anchor{XREFuimenucreatefcn}
@prindex uimenu createfcn
@item @code{createfcn}: string | function handle, def. @code{[](0x0)}
Callback function executed immediately after uimenu has been created.  Function is set by using default property on root object, e.g., @code{set (groot, "defaultuimenucreatefcn", 'disp ("uimenu created!")')}.

For information on how to write graphics listener functions see @ref{Callbacks, , @w{Callbacks section}}.


@anchor{XREFuimenudeletefcn}
@prindex uimenu deletefcn
@item @code{deletefcn}: string | function handle, def. @code{[](0x0)}

@prindex uimenu visible
@item @code{visible}: @qcode{"off"} | @{@qcode{"on"}@}
If @code{visible} is @qcode{"off"}, the uimenu is not rendered on screen.

@subsubheading Keyboard Interaction

@table @asis

@anchor{XREFuimenuaccelerator}
@prindex uimenu accelerator
@item @code{accelerator}: character, def. @qcode{""}
A character that when pressed together with CTRL will execute this menu entry (e.g., @qcode{"x"} for @code{CTRL+x}).

@end table

@subsubheading Menu Options

@table @asis

@anchor{XREFuimenuchecked}
@prindex uimenu checked
@item @code{checked}: @{@qcode{"off"}@} | @qcode{"on"}
Sets whether or not a mark appears at this menu entry.


@anchor{XREFuimenuenable}
@prindex uimenu enable
@item @code{enable}: @qcode{"off"} | @{@qcode{"on"}@}
Sets whether this menu entry is active or is grayed out.


@anchor{XREFuimenutext}
@prindex uimenu text
@item @code{text}: string, def. @qcode{""}
The text for this menu entry.  A @qcode{"&"} character can be used to mark the @ref{XREFuimenuaccelerator, , @w{@qcode{"accelerator"} key}}

@end table

@anchor{XREFuimenucategoryMouseInteraction}
@subsubheading Mouse Interaction

@table @asis

@anchor{XREFuimenubuttondownfcn}
@prindex uimenu buttondownfcn
@item @code{buttondownfcn}: string | function handle, def. @code{[](0x0)}
@code{buttondownfcn} is unused.


@anchor{XREFuimenucontextmenu}
@prindex uimenu contextmenu
@item @code{contextmenu}: graphics handle, def. @code{[](0x0)}
Graphics handle of the uicontextmenu object that is currently associated to this uimenu object.


@anchor{XREFuimenuhittest}
@prindex uimenu hittest
@item @code{hittest}: @qcode{"off"} | @{@qcode{"on"}@}
Specify whether uimenu 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{XREFuimenupickableparts, , @w{pickableparts property}}.


@anchor{XREFuimenupickableparts}
@prindex uimenu pickableparts
@item @code{pickableparts}: @qcode{"all"} | @qcode{"none"} | @{@qcode{"visible"}@}
Specify whether uimenu will accept mouse clicks.  By default, @code{pickableparts} is @qcode{"visible"} and only visible parts of the uimenu 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{XREFuimenuhittest, , @w{hittest property}}.


@anchor{XREFuimenuselected}
@prindex uimenu selected
@item @code{selected}: @{@qcode{"off"}@} | @qcode{"on"}

@anchor{XREFuimenuselectionhighlight}
@prindex uimenu selectionhighlight
@item @code{selectionhighlight}: @qcode{"off"} | @{@qcode{"on"}@}
If @code{selectionhighlight} is @qcode{"on"}, then the uimenu's selection state is visually highlighted.
