@subsubheading Callback Execution

@table @asis

@anchor{XREFuitoolbarbusyaction}
@prindex uitoolbar 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{XREFuitoolbarinterruptible}
@prindex uitoolbar 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}}.

@subsubheading Creation/Deletion

@table @asis

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

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


@anchor{XREFuitoolbardeletefcn}
@prindex uitoolbar deletefcn
@item @code{deletefcn}: string | function handle, def. @code{[](0x0)}
Callback function executed immediately before uitoolbar is deleted.

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

@table @asis

@anchor{XREFuitoolbarclipping}
@prindex uitoolbar clipping
@item @code{clipping}: @qcode{"off"} | @{@qcode{"on"}@}
If @code{clipping} is @qcode{"on"}, the uitoolbar is clipped in its parent axes limits.


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

@table @asis

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


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


@anchor{XREFuitoolbarhittest}
@prindex uitoolbar hittest
@item @code{hittest}: @qcode{"off"} | @{@qcode{"on"}@}
Specify whether uitoolbar 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{XREFuitoolbarpickableparts, , @w{pickableparts property}}.


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


@anchor{XREFuitoolbarselected}
@prindex uitoolbar selected
@item @code{selected}: @{@qcode{"off"}@} | @qcode{"on"}
Property indicates whether this uitoolbar is selected.


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

User-defined data to associate with the graphics object.

@anchor{XREFuitoolbarhandlevisibility}
@prindex uitoolbar handlevisibility
@item @code{handlevisibility}: @qcode{"callback"} | @qcode{"off"} | @{@qcode{"on"}@}

@anchor{XREFuitoolbarparent}
@prindex uitoolbar parent
@item @code{parent}: graphics handle
Handle of the parent graphics object.
