#### 15.3.3.1 Root Properties

Properties of the root graphics object:

`beingdeleted`: {`"off"`} | `"on"`

  `beingdeleted` is unused.

`busyaction`: `"cancel"` | {`"queue"`}

  `busyaction` is unused.

`buttondownfcn`: string | function handle, def. `[](0x0)`

  `buttondownfcn` is unused.

`callbackobject` (read-only): graphics handle, def. `[](0x0)`

  Graphics handle of the current object whose callback is executing.

`children` (read-only): vector of graphics handles, def. `[](0x1)`

  Graphics handles of the root’s children.

`clipping`: `"off"` | {`"on"`}

  `clipping` is unused.

`commandwindowsize` (read-only): def. `[0 0]`
`contextmenu`: graphics handle, def. `[](0x0)`

  Graphics handle of the uicontextmenu object that is currently associated to this root object.

`createfcn`: string | function handle, def. `[](0x0)`

  `createfcn` is unused.

`currentfigure`: graphics handle, def. `[](0x0)`

  Graphics handle of the current figure.

`deletefcn`: string | function handle, def. `[](0x0)`

  `deletefcn` is unused.

`fixedwidthfontname`: string, def. `"Courier"`
`handlevisibility`: `"callback"` | `"off"` | {`"on"`}

  `handlevisibility` is unused.

`hittest`: `"off"` | {`"on"`}

  `hittest` is unused.

`interruptible`: `"off"` | {`"on"`}

  `interruptible` is unused.

`monitorpositions` (read-only):

  `monitorpositions` is unused.

`parent`: graphics handle, def. `[](0x0)`

  Root object has no parent graphics object. `parent` is always empty.

`pickableparts`: `"all"` | `"none"` | {`"visible"`}

  `pickableparts` is unused.

`pointerlocation`: two-element vector, def. `[0 0]`

  `pointerlocation` is unused.

`pointerwindow` (read-only): graphics handle, def. `0`

  `pointerwindow` is unused.

`screendepth` (read-only): double
`screenpixelsperinch` (read-only): double
`screensize` (read-only): four-element vector
`selected`: {`"off"`} | `"on"`

  `selected` is unused.

`selectionhighlight`: `"off"` | {`"on"`}

  `selectionhighlight` is unused.

`showhiddenhandles`: {`"off"`} | `"on"`

  If `showhiddenhandles` is `"on"`, all graphics objects handles are visible in their parents’ children list, regardless of the value of their `handlevisibility` property.

`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 `"root"`

`units`: `"centimeters"` | `"characters"` | `"inches"` | `"normalized"` | {`"pixels"`} | `"points"`
`userdata`: Any Octave data, def. `[](0x0)`

  User-defined data to associate with the graphics object.

`visible`: `"off"` | {`"on"`}

  `visible` is unused.
