#### 15.3.3.5 Text Properties

The `text` properties are:

`backgroundcolor`: colorspec, def. `"none"`

  Color of the background area. See colorspec.

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

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

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

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

  `children` is unused.

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

  If `clipping` is `"on"`, the text is clipped in its parent axes limits.

`color`: colorspec, def. `[0 0 0]`

  Color of the text. See colorspec.

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

  Callback function executed immediately after text has been created. Function is set by using default property on root object, e.g., `set (groot, "defaulttextcreatefcn", 'disp ("text created!")')`.

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

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

  Callback function executed immediately before text is deleted.

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

`edgecolor`: colorspec, def. `"none"`

  Color of the outline of the background area. See colorspec.

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

  `editing` is unused.

`extent` (read-only): four-element vector, def. `[0.000000 -0.005843 0.000000 0.032136]`

  Vector `[x0 y0 width height]` indicating the size and location of the text string.

`fontangle`: `"italic"` | {`"normal"`} | `"oblique"`

  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).

`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"` | `"demi"` | `"light"` | {`"normal"`}

  Control the variant of the base font used for text rendering.

`handlevisibility`: `"callback"` | `"off"` | {`"on"`}

  If `handlevisibility` is `"off"`, the text’s handle is not visible in its parent’s "children" property.

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

  Specify whether text 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.

`horizontalalignment`: `"center"` | {`"left"`} | `"right"`
`interpreter`: `"latex"` | `"none"` | {`"tex"`}

  Control the way the `"string"` property is interpreted. See Use of the interpreter property.

`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.

`linestyle`: {`"-"`} | `"--"` | `"-."` | `":"` | `"none"`

  Style of the outline. See Line Styles.

`linewidth`: scalar, def. `0.50000`

  Width of the outline.

`margin`: scalar, def. `2`

  Margins between the borders of the background area and the texts. The value is currently interpreted as pixels, regardless of the `"fontunits"` property.

`parent`: graphics handle

  Handle of the parent graphics object.

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

  Specify whether text will accept mouse clicks. By default, `pickableparts` is `"visible"` and only visible parts of the text 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.

`position`: four-element vector, def. `[0 0 0]`

  Vector `[X0 Y0 Z0]` where X0, Y0 and Z0 indicate the position of the text anchor as defined by `verticalalignment` and `horizontalalignment`.

`rotation`: scalar, def. `0`

  The angle of rotation for the displayed text, measured in degrees.

`selected`: {`"off"`} | `"on"`
`selectionhighlight`: `"off"` | {`"on"`}
`string`: string, def. `""`

  The text object string content.

`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 `"text"`

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

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

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

  User-defined data to associate with the graphics object.

`verticalalignment`: `"baseline"` | `"bottom"` | `"cap"` | {`"middle"`} | `"top"`
`visible`: `"off"` | {`"on"`}

  If `visible` is `"off"`, the text is not rendered on screen.
