RichTextLabel
=============

**Inherits:** :ref:`Control<class_Control>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

Label that displays rich text.

Description
-----------

Rich text can contain custom text, fonts, images and some basic formatting. The label manages these as an internal tag stack. It also adapts itself to given width/heights.

**Note:** Assignments to :ref:`bbcode_text<class_RichTextLabel_property_bbcode_text>` clear the tag stack and reconstruct it from the property's contents. Any edits made to :ref:`bbcode_text<class_RichTextLabel_property_bbcode_text>` will erase previous edits made from other manual sources such as :ref:`append_bbcode<class_RichTextLabel_method_append_bbcode>` and the ``push_*`` / :ref:`pop<class_RichTextLabel_method_pop>` methods.

**Note:** RichTextLabel doesn't support entangled BBCode tags. For example, instead of using ``[b]bold[i]bold italic[/b]italic[/i]``, use ``[b]bold[i]bold italic[/i][/b][i]italic[/i]``.

**Note:** Unlike :ref:`Label<class_Label>`, RichTextLabel doesn't have a *property* to horizontally align text to the center. Instead, enable :ref:`bbcode_enabled<class_RichTextLabel_property_bbcode_enabled>` and surround the text in a ``[center]`` tag as follows: ``[center]Example[/center]``. There is currently no built-in way to vertically align text either, but this can be emulated by relying on anchors/containers and the :ref:`fit_content_height<class_RichTextLabel_property_fit_content_height>` property.

Signals
-------

.. _class_RichTextLabel_signal_meta_clicked:

- **meta_clicked** **(** :ref:`Variant<class_Variant>` meta **)**

Triggered when the user clicks on content between meta tags. If the meta is defined in text, e.g. ``[url={"data"="hi"}]hi[/url]``, then the parameter for this signal will be a :ref:`String<class_String>` type. If a particular type or an object is desired, the :ref:`push_meta<class_RichTextLabel_method_push_meta>` method must be used to manually insert the data into the tag stack.

----

.. _class_RichTextLabel_signal_meta_hover_ended:

- **meta_hover_ended** **(** :ref:`Variant<class_Variant>` meta **)**

Triggers when the mouse exits a meta tag.

----

.. _class_RichTextLabel_signal_meta_hover_started:

- **meta_hover_started** **(** :ref:`Variant<class_Variant>` meta **)**

Triggers when the mouse enters a meta tag.

Property Descriptions
---------------------

.. _class_RichTextLabel_property_bbcode_enabled:

- :ref:`bool<class_bool>` **bbcode_enabled**

+-----------+-----------------------+
| *Default* | ``false``             |
+-----------+-----------------------+
| *Setter*  | set_use_bbcode(value) |
+-----------+-----------------------+
| *Getter*  | is_using_bbcode()     |
+-----------+-----------------------+

If ``true``, the label uses BBCode formatting.

**Note:** Trying to alter the ``RichTextLabel``'s text with :ref:`add_text<class_RichTextLabel_method_add_text>` will reset this to ``false``. Use instead :ref:`append_bbcode<class_RichTextLabel_method_append_bbcode>` to preserve BBCode formatting.

----

.. _class_RichTextLabel_property_bbcode_text:

- :ref:`String<class_String>` **bbcode_text**

+-----------+-------------------+
| *Default* | ``""``            |
+-----------+-------------------+
| *Setter*  | set_bbcode(value) |
+-----------+-------------------+
| *Getter*  | get_bbcode()      |
+-----------+-------------------+

The label's text in BBCode format. Is not representative of manual modifications to the internal tag stack. Erases changes made by other methods when edited.

**Note:** It is unadvised to use the ``+=`` operator with ``bbcode_text`` (e.g. ``bbcode_text += "some string"``) as it replaces the whole text and can cause slowdowns. Use :ref:`append_bbcode<class_RichTextLabel_method_append_bbcode>` for adding text instead, unless you absolutely need to close a tag that was opened in an earlier method call.

----

.. _class_RichTextLabel_property_custom_effects:

- :ref:`Array<class_Array>` **custom_effects**

+-----------+--------------------+
| *Default* | ``[  ]``           |
+-----------+--------------------+
| *Setter*  | set_effects(value) |
+-----------+--------------------+
| *Getter*  | get_effects()      |
+-----------+--------------------+

The currently installed custom effects. This is an array of :ref:`RichTextEffect<class_RichTextEffect>`\ s.

To add a custom effect, it's more convenient to use :ref:`install_effect<class_RichTextLabel_method_install_effect>`.

----

.. _class_RichTextLabel_property_fit_content_height:

- :ref:`bool<class_bool>` **fit_content_height**

+-----------+---------------------------------+
| *Default* | ``false``                       |
+-----------+---------------------------------+
| *Setter*  | set_fit_content_height(value)   |
+-----------+---------------------------------+
| *Getter*  | is_fit_content_height_enabled() |
+-----------+---------------------------------+

If ``true``, the label's height will be automatically updated to fit its content.

**Note:** This property is used as a workaround to fix issues with ``RichTextLabel`` in :ref:`Container<class_Container>`\ s, but it's unreliable in some cases and will be removed in future versions.

----

.. _class_RichTextLabel_property_meta_underlined:

- :ref:`bool<class_bool>` **meta_underlined**

+-----------+---------------------------+
| *Default* | ``true``                  |
+-----------+---------------------------+
| *Setter*  | set_meta_underline(value) |
+-----------+---------------------------+
| *Getter*  | is_meta_underlined()      |
+-----------+---------------------------+

If ``true``, the label underlines meta tags such as ``[url]{text}[/url]``.

----

.. _class_RichTextLabel_property_override_selected_font_color:

- :ref:`bool<class_bool>` **override_selected_font_color**

+-----------+-----------------------------------------+
| *Default* | ``false``                               |
+-----------+-----------------------------------------+
| *Setter*  | set_override_selected_font_color(value) |
+-----------+-----------------------------------------+
| *Getter*  | is_overriding_selected_font_color()     |
+-----------+-----------------------------------------+

If ``true``, the label uses the custom font color.

----

.. _class_RichTextLabel_property_percent_visible:

- :ref:`float<class_float>` **percent_visible**

+-----------+----------------------------+
| *Default* | ``1.0``                    |
+-----------+----------------------------+
| *Setter*  | set_percent_visible(value) |
+-----------+----------------------------+
| *Getter*  | get_percent_visible()      |
+-----------+----------------------------+

The range of characters to display, as a :ref:`float<class_float>` between 0.0 and 1.0. When assigned an out of range value, it's the same as assigning 1.0.

**Note:** Setting this property updates :ref:`visible_characters<class_RichTextLabel_property_visible_characters>` based on current :ref:`get_total_character_count<class_RichTextLabel_method_get_total_character_count>`.

----

.. _class_RichTextLabel_property_scroll_active:

- :ref:`bool<class_bool>` **scroll_active**

+-----------+--------------------------+
| *Default* | ``true``                 |
+-----------+--------------------------+
| *Setter*  | set_scroll_active(value) |
+-----------+--------------------------+
| *Getter*  | is_scroll_active()       |
+-----------+--------------------------+

If ``true``, the scrollbar is visible. Setting this to ``false`` does not block scrolling completely. See :ref:`scroll_to_line<class_RichTextLabel_method_scroll_to_line>`.

----

.. _class_RichTextLabel_property_scroll_following:

- :ref:`bool<class_bool>` **scroll_following**

+-----------+--------------------------+
| *Default* | ``false``                |
+-----------+--------------------------+
| *Setter*  | set_scroll_follow(value) |
+-----------+--------------------------+
| *Getter*  | is_scroll_following()    |
+-----------+--------------------------+

If ``true``, the window scrolls down to display new content automatically.

----

.. _class_RichTextLabel_property_selection_enabled:

- :ref:`bool<class_bool>` **selection_enabled**

+-----------+------------------------------+
| *Default* | ``false``                    |
+-----------+------------------------------+
| *Setter*  | set_selection_enabled(value) |
+-----------+------------------------------+
| *Getter*  | is_selection_enabled()       |
+-----------+------------------------------+

If ``true``, the label allows text selection.

----

.. _class_RichTextLabel_property_tab_size:

- :ref:`int<class_int>` **tab_size**

+-----------+---------------------+
| *Default* | ``4``               |
+-----------+---------------------+
| *Setter*  | set_tab_size(value) |
+-----------+---------------------+
| *Getter*  | get_tab_size()      |
+-----------+---------------------+

The number of spaces associated with a single tab length. Does not affect ``\t`` in text tags, only indent tags.

----

.. _class_RichTextLabel_property_text:

- :ref:`String<class_String>` **text**

+-----------+-----------------+
| *Default* | ``""``          |
+-----------+-----------------+
| *Setter*  | set_text(value) |
+-----------+-----------------+
| *Getter*  | get_text()      |
+-----------+-----------------+

The raw text of the label.

When set, clears the tag stack and adds a raw text tag to the top of it. Does not parse BBCodes. Does not modify :ref:`bbcode_text<class_RichTextLabel_property_bbcode_text>`.

----

.. _class_RichTextLabel_property_visible_characters:

- :ref:`int<class_int>` **visible_characters**

+-----------+-------------------------------+
| *Default* | ``-1``                        |
+-----------+-------------------------------+
| *Setter*  | set_visible_characters(value) |
+-----------+-------------------------------+
| *Getter*  | get_visible_characters()      |
+-----------+-------------------------------+

The restricted number of characters to display in the label. If ``-1``, all characters will be displayed.

**Note:** Setting this property updates :ref:`percent_visible<class_RichTextLabel_property_percent_visible>` based on current :ref:`get_total_character_count<class_RichTextLabel_method_get_total_character_count>`.

Method Descriptions
-------------------

.. _class_RichTextLabel_method_add_image:

- void **add_image** **(** :ref:`Texture<class_Texture>` image, :ref:`int<class_int>` width=0, :ref:`int<class_int>` height=0 **)**

Adds an image's opening and closing tags to the tag stack, optionally providing a ``width`` and ``height`` to resize the image.

If ``width`` or ``height`` is set to 0, the image size will be adjusted in order to keep the original aspect ratio.

----

.. _class_RichTextLabel_method_add_text:

- void **add_text** **(** :ref:`String<class_String>` text **)**

Adds raw non-BBCode-parsed text to the tag stack.

**Note:** Using this method, you can't close a tag that was opened in a previous :ref:`append_bbcode<class_RichTextLabel_method_append_bbcode>` call. This is done to improve performance, especially when updating large RichTextLabels since rebuilding the whole BBCode every time would be slower. If you absolutely need to close a tag in a future method call, append the :ref:`bbcode_text<class_RichTextLabel_property_bbcode_text>` instead of using :ref:`append_bbcode<class_RichTextLabel_method_append_bbcode>`.

----

.. _class_RichTextLabel_method_scroll_to_line:

- void **scroll_to_line** **(** :ref:`int<class_int>` line **)**

Scrolls the window's top line to match ``line``.

----

.. _class_RichTextLabel_method_set_table_column_expand:

- void **set_table_column_expand** **(** :ref:`int<class_int>` column, :ref:`bool<class_bool>` expand, :ref:`int<class_int>` ratio **)**
