The ‘root figure’ properties are:

‘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]’

‘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"

     their ‘handlevisibility’ property.

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