@table @asis

@anchor{XREFuipushtoolbusyaction}
@prindex uipushtool 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{XREFuipushtoolclickedcallback}
@prindex uipushtool clickedcallback
@item @code{clickedcallback}: string, def. @code{[](0x0)}
A string consisting of a valid Octave expression that will be executed whenever this control object is clicked.


@anchor{XREFuipushtoolinterruptible}
@prindex uipushtool 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}}.

@table @asis

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

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


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

@table @asis

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


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

@table @asis

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


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


@anchor{XREFuipushtoolhittest}
@prindex uipushtool hittest
@item @code{hittest}: @qcode{"off"} | @{@qcode{"on"}@}
Specify whether uipushtool 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{XREFuipushtoolpickableparts,,@w{pickableparts property}}.


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


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


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


@anchor{XREFuipushtooltooltipstring}
@prindex uipushtool tooltipstring
@item @code{tooltipstring}: string, def. @qcode{""}
A text string that appears in a tooltip when the mouse pointer hovers over the pushtool object.
