Signals
-------

.. _class_RichTextLabel_meta_clicked:

- **meta_clicked** **(** :ref:`Nil<class_nil>` meta **)**

Triggered when the user clicks on content between url 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_push_meta>` method must be used to manually insert the data into the tag stack.

.. _class_RichTextLabel_meta_hover_ended:

- **meta_hover_ended** **(** :ref:`Nil<class_nil>` meta **)**

Triggers when the mouse exits a meta tag.

.. _class_RichTextLabel_meta_hover_started:

- **meta_hover_started** **(** :ref:`Nil<class_nil>` meta **)**

Triggers when the mouse enters a meta tag.

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 that assignments to :ref:`bbcode_text<class_RichTextLabel_bbcode_text>` clear the tag stack and reconstruct it from the property's contents. Any edits made to :ref:`bbcode_text<class_RichTextLabel_bbcode_text>` will erase previous edits made from other manual sources such as :ref:`append_bbcode<class_RichTextLabel_append_bbcode>` and the ``push_*`` / :ref:`pop<class_RichTextLabel_pop>` methods.

Member Function Description
---------------------------

.. _class_RichTextLabel_add_image:

- void **add_image** **(** :ref:`Texture<class_texture>` image **)**

Adds an image's opening and closing tags to the tag stack.

.. _class_RichTextLabel_add_text:

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

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

.. _class_RichTextLabel_append_bbcode:

- :ref:`int<class_int>` **append_bbcode** **(** :ref:`String<class_string>` bbcode **)**

Parses ``bbcode`` and adds tags to the tag stack as needed. Returns the result of the parsing, ``OK`` if successful.

.. _class_RichTextLabel_clear:

- void **clear** **(** **)**

Clears the tag stack and sets :ref:`bbcode_text<class_RichTextLabel_bbcode_text>` to an empty string.

.. _class_RichTextLabel_get_line_count:

- :ref:`int<class_int>` **get_line_count** **(** **)** const

Returns the total number of newlines in the tag stack's text tags. Considers wrapped text as one line.

.. _class_RichTextLabel_get_total_character_count:

- :ref:`int<class_int>` **get_total_character_count** **(** **)** const

Returns the total number of characters from text tags. Does not include bbcodes.

.. _class_RichTextLabel_get_v_scroll:

- :ref:`VScrollBar<class_vscrollbar>` **get_v_scroll** **(** **)**

Returns the vertical scrollbar.

.. _class_RichTextLabel_get_visible_line_count:

- :ref:`int<class_int>` **get_visible_line_count** **(** **)** const

Returns the number of visible lines.

.. _class_RichTextLabel_newline:

- void **newline** **(** **)**

Adds a newline tag to the tag stack.

.. _class_RichTextLabel_parse_bbcode:

- :ref:`int<class_int>` **parse_bbcode** **(** :ref:`String<class_string>` bbcode **)**

The assignment version of :ref:`append_bbcode<class_RichTextLabel_append_bbcode>`. Clears the tag stack and inserts the new content. Returns ``OK`` if parses ``bbcode`` successfully.

.. _class_RichTextLabel_pop:

- void **pop** **(** **)**

Terminates the current tag. Use after ``push_*`` methods to close bbcodes manually. Does not need to follow ``add_*`` methods.

.. _class_RichTextLabel_push_align:

- void **push_align** **(** :ref:`int<class_int>` align **)**

Adds a ``[right]`` tag to the tag stack.

.. _class_RichTextLabel_push_cell:

- void **push_cell** **(** **)**

Adds a ``[cell]`` tag to the tag stack. Must be inside a table tag. See :ref:`push_table<class_RichTextLabel_push_table>` for details.

.. _class_RichTextLabel_push_color:

- void **push_color** **(** :ref:`Color<class_color>` color **)**

Adds a ``[color]`` tag to the tag stack.

.. _class_RichTextLabel_push_font:

- void **push_font** **(** :ref:`Font<class_font>` font **)**

Adds a ``[font]`` tag to the tag stack. Overrides default fonts for its duration.

.. _class_RichTextLabel_push_indent:

- void **push_indent** **(** :ref:`int<class_int>` level **)**

Adds an ``[indent]`` tag to the tag stack. Multiplies "level" by current tab_size to determine new margin length.

.. _class_RichTextLabel_push_list:

- void **push_list** **(** :ref:`int<class_int>` type **)**

Adds a list tag to the tag stack. Similar to the bbcodes ``[ol]`` or ``[ul]``, but supports more list types. Not fully implemented!

.. _class_RichTextLabel_push_meta:

- void **push_meta** **(** :ref:`Variant<class_variant>` data **)**

Adds a meta tag to the tag stack. Similar to the bbcode ``[url=something]{text}[/url]``, but supports non-:ref:`String<class_string>` metadata types.

.. _class_RichTextLabel_push_table:

- void **push_table** **(** :ref:`int<class_int>` columns **)**

Adds a ``[table=columns]`` tag to the tag stack.

.. _class_RichTextLabel_push_underline:

- void **push_underline** **(** **)**

Adds a ``[u]`` tag to the tag stack.

.. _class_RichTextLabel_remove_line:

- :ref:`bool<class_bool>` **remove_line** **(** :ref:`int<class_int>` line **)**

Removes a line of content from the label. Returns ``true`` if the line exists.

.. _class_RichTextLabel_scroll_to_line:

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

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

.. _class_RichTextLabel_set_table_column_expand:

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

Edits the selected columns expansion options. If ``expand`` is ``true``, the column expands in proportion to its expansion ratio versus the other columns' ratios.

For example, 2 columns with ratios 3 and 4 plus 70 pixels in available width would expand 30 and 40 pixels, respectively.

Columns with a ``false`` expand will not contribute to the total ratio.
