  9. Label that displays rich text.
  10. Description
  11. -----------
  12. 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.
  13. **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.

  151. -------
  152. .. _class_RichTextLabel_signal_meta_clicked:
  153. - **meta_clicked** **(** :ref:`Variant<class_Variant>` meta **)**
  154. 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.

  248. **Note:** It is unadvised to use ``+=`` 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.

  294. **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>`.
