@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"}).

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


@anchor{XREFuibuttongrouphittest}
@prindex uibuttongroup hittest
@item @code{hittest}: @qcode{"off"} | @{@qcode{"on"}@}
Specify whether uibuttongroup 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{XREFuibuttongrouppickableparts, , @w{pickableparts property}}.


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


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