Appearance
..........

backgroundcolor: colorspec, def. [0.9400   0.9400   0.9400]
     The color value of the background of this buttongroup.

bordertype: "beveledin" | "beveledout" | {"etchedin"} | "etchedout" | "line" | "none"
     Sets whether or not a line border will surround the buttongroup.

borderwidth: whole number scalar, def. 1
     The width of the line border in pixels.

foregroundcolor: colorspec, def. [0   0   0]
     The color value of the title text for this buttongroup.

highlightcolor: colorspec, def. [1   1   1]
     The color value of the line bordering this buttongroup.

shadowcolor: colorspec, def. [0.7000   0.7000   0.7000]
     The color value of the line surrounding the border line around this buttongroup.

sizechangedfcn: string | function handle, def. [](0x0)
     Callback triggered when the buttongroup size is changed.

     For information on how to write graphics listener functions see Callbacks section.

Button Group Operation
......................

selectedobject: def. [](0x0)
     Graphic handle of the currently selected item in the buttongroup.

Callback Execution
..................

busyaction: "cancel" | {"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 interruptible property set to "off".  The busyaction property of the interrupting callback object indicates whether the interrupting callback is queued ("queue" (default)) or discarded ("cancel"). See Callbacks section.

interruptible: "off" | {"on"}
     Specify whether this object's callback functions may be interrupted by other callbacks.  By default interruptible is "on" and callbacks that make use of drawnow, figure, waitfor, getframe or pause functions are eventually interrupted. See Callbacks section.

resizefcn: string | function handle, def. [](0x0)
     resizefcn is deprecated.  Use sizechangedfcn instead.

selectionchangedfcn: string | function handle, def. [](0x0)
     Callback triggered when the selected item within the buttongroup is changed.

     For information on how to write graphics listener functions see Callbacks section.

Creation/Deletion
.................

beingdeleted: {"off"} | "on"
     Property indicating that a function has initiated deletion of the object.  beingdeleted is set to true until the object no longer exists.

createfcn: string | function handle, def. [](0x0)
     Callback function executed immediately after uibuttongroup has been created.  Function is set by using default property on root object, e.g., set (groot, "defaultuibuttongroupcreatefcn", 'disp ("uibuttongroup created!")').

     For information on how to write graphics listener functions see Callbacks section.

deletefcn: string | function handle, def. [](0x0)
     Callback function executed immediately before uibuttongroup is deleted.

     For information on how to write graphics listener functions see Callbacks section.

Display
.......

clipping: "off" | {"on"}
     If clipping is "on", the uibuttongroup is clipped in its parent axes limits.

visible: "off" | {"on"}
     If visible is "off", the uibuttongroup is not rendered on screen.

Mouse Interaction
.................

buttondownfcn: string | function handle, def. [](0x0)
     For information on how to write graphics listener functions see Callbacks section.

contextmenu: graphics handle, def. [](0x0)
     Graphics handle of the uicontextmenu object that is currently associated to this uibuttongroup object.

hittest: "off" | {"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 "buttondownfcn", showing the uicontextmenu, and eventually becoming the root "currentobject".  This property is only relevant when the object can accept mouse clicks which is determined by the "pickableparts" property.  See pickableparts property.

pickableparts: "all" | "none" | {"visible"}
     Specify whether uibuttongroup will accept mouse clicks.  By default, pickableparts is "visible" and only visible parts of the uibuttongroup or its children may react to mouse clicks.  When pickableparts is "all" both visible and invisible parts (or children) may react to mouse clicks.  When pickableparts is "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 "hittest" property will determine how they are processed.  See hittest property.

selected: {"off"} | "on"
     Property indicates whether this uibuttongroup is selected.

selectionhighlight: "off" | {"on"}
     If selectionhighlight is "on", then the uibuttongroup's selection state is visually highlighted.

Object Identification
.....................

tag: string, def. ""
     A user-defined string to label the graphics object.

type (read-only): string
     Class name of the graphics object.  type is always "uibuttongroup".

userdata: Any Octave data, def. [](0x0)
     User-defined data to associate with the graphics object.

Object Position
...............

position: four-element vector, def. [0   0   1   1]
     Size of the buttongroup represented as the four-element vector [left, bottom, width, height].

units: "centimeters" | "characters" | "inches" | {"normalized"} | "pixels" | "points"
     Unit of measurement used to interpret the "position" property.

Parent/Children
...............

children (read-only): vector of graphics handles, def. [](0x1)
     Graphics handles of the uibuttongroup's children.

handlevisibility: "callback" | "off" | {"on"}
     If handlevisibility is "off", the uibuttongroup's handle is not visible in its parent's "children" property.

parent: graphics handle
     Handle of the parent graphics object.

Text Appearance
...............

fontangle: "italic" | {"normal"}
     Control whether the font is italic or normal.

fontname: string, def. "*"
     Name of font used for text rendering.  When setting this property, the text rendering engine will search for a matching font in your system.  If none is found then text is rendered using a default sans serif font (same as the default "*" value).

     Programming Note: On systems that don’t use FontConfig natively (all but Linux), the font cache is built when Octave is installed.  You will need to run system ("fc-cache -fv") manually after installing new fonts.

fontsize: scalar, def. 10
     Size of the font used for text rendering.  See fontunits property.

fontunits: "centimeters" | "inches" | "normalized" | "pixels" | {"points"}
     Units used to interpret the "fontsize" property.

fontweight: "bold" | {"normal"}
     Control the variant of the base font used for text rendering.

title: string, def. ""
     The text for the buttongroup title.

titleposition: "centerbottom" | "centertop" | "leftbottom" | {"lefttop"} | "rightbottom" | "righttop"
     Relative position of the title within the buttongroup.
