RichTextLabel

Inherits: Control < CanvasItem < Node < 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 text clear the tag stack and reconstruct it from the property's contents. Any edits made to text will erase previous edits made from other manual sources such as append_text and the push_* / 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: push_*/pop functions won't affect BBCode.

Note: Unlike Label, RichTextLabel doesn't have a property to horizontally align text to the center. Instead, enable 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 fit_content property.

Signals

finished ( )

Triggered when the document is fully loaded.

meta_clicked ( 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 String type. If a particular type or an object is desired, the push_meta method must be used to manually insert the data into the tag stack.

meta_hover_ended ( Variant meta )

Triggers when the mouse exits a meta tag.

meta_hover_started ( Variant meta )

Triggers when the mouse enters a meta tag.

Enumerations

enum ListType:

ListType LIST_LETTERS = 1

Each list item has a letter marker.

ListType LIST_ROMAN = 2

Each list item has a roman number marker.

ListType LIST_DOTS = 3

Each list item has a filled circle marker.

enum MenuItems:

MenuItems MENU_COPY = 0

Copies the selected text.

MenuItems MENU_SELECT_ALL = 1

Selects the whole RichTextLabel text.

MenuItems MENU_MAX = 2

Represents the size of the MenuItems enum.

Property Descriptions

AutowrapMode autowrap_mode = 3

If set to something other than TextServer.AUTOWRAP_OFF, the text gets wrapped inside the node's bounding rectangle. To see how each mode behaves, see AutowrapMode.

bool bbcode_enabled = false

  • void set_use_bbcode ( bool value )

  • bool is_using_bbcode ( )

If true, the label uses BBCode formatting.

bool context_menu_enabled = false

  • void set_context_menu_enabled ( bool value )

  • bool is_context_menu_enabled ( )

If true, a right-click displays the context menu.

Array custom_effects = []

  • void set_effects ( Array value )

  • Array get_effects ( )

The currently installed custom effects. This is an array of RichTextEffects.

To add a custom effect, it's more convenient to use install_effect.

bool deselect_on_focus_loss_enabled = true

  • void set_deselect_on_focus_loss_enabled ( bool value )

  • bool is_deselect_on_focus_loss_enabled ( )

If true, the selected text will be deselected when focus is lost.

bool fit_content = false

  • void set_fit_content ( bool value )

  • bool is_fit_content_enabled ( )

If true, the label's minimum size will be automatically updated to fit its content, matching the behavior of Label.

bool hint_underlined = true

  • void set_hint_underline ( bool value )

  • bool is_hint_underlined ( )

If true, the label underlines hint tags such as [hint=description]{text}[/hint].

String language = ""

  • void set_language ( String value )

  • String get_language ( )

Language code used for line-breaking and text shaping algorithms, if left empty current locale is used instead.

bool meta_underlined = true

  • void set_meta_underline ( bool value )

  • bool is_meta_underlined ( )

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

int progress_bar_delay = 1000

  • void set_progress_bar_delay ( int value )

  • int get_progress_bar_delay ( )

The delay after which the loading progress bar is displayed, in milliseconds. Set to -1 to disable progress bar entirely.

Note: Progress bar is displayed only if threaded is enabled.

bool scroll_active = true

  • void set_scroll_active ( bool value )

  • bool is_scroll_active ( )

If true, the scrollbar is visible. Setting this to false does not block scrolling completely. See scroll_to_line.

bool scroll_following = false

  • void set_scroll_follow ( bool value )

  • bool is_scroll_following ( )

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

bool selection_enabled = false

  • void set_selection_enabled ( bool value )

  • bool is_selection_enabled ( )

If true, the label allows text selection.

bool shortcut_keys_enabled = true

  • void set_shortcut_keys_enabled ( bool value )

  • bool is_shortcut_keys_enabled ( )

If true, shortcut keys for context menu items are enabled, even if the context menu is disabled.

StructuredTextParser structured_text_bidi_override = 0

Set BiDi algorithm override for the structured text.

Array structured_text_bidi_override_options = []

  • void set_structured_text_bidi_override_options ( Array value )

  • Array get_structured_text_bidi_override_options ( )

Set additional options for BiDi override.

int tab_size = 4

  • void set_tab_size ( int value )

  • int get_tab_size ( )

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

String text = ""

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: If bbcode_enabled is true, it is unadvised to use the += operator with text (e.g. text += "some string") as it replaces the whole text and can cause slowdowns. It will also erase all BBCode that was added to stack using push_* methods. Use append_text for adding text instead, unless you absolutely need to close a tag that was opened in an earlier method call.

TextDirection text_direction = 0

Base text writing direction.

bool threaded = false

  • void set_threaded ( bool value )

  • bool is_threaded ( )

If true, text processing is done in a background thread.

int visible_characters = -1

  • void set_visible_characters ( int value )

  • int get_visible_characters ( )

The number of characters to display. If set to -1, all characters are displayed. This can be useful when animating the text appearing in a dialog box.

Note: Setting this property updates visible_ratio accordingly.

VisibleCharactersBehavior visible_characters_behavior = 0

Sets the clipping behavior when visible_characters or visible_ratio is set. See VisibleCharactersBehavior for more info.

float visible_ratio = 1.0

  • void set_visible_ratio ( float value )

  • float get_visible_ratio ( )

The fraction of characters to display, relative to the total number of characters (see get_total_character_count). If set to 1.0, all characters are displayed. If set to 0.5, only half of the characters will be displayed. This can be useful when animating the text appearing in a dialog box.

Note: Setting this property updates visible_characters accordingly.

Method Descriptions

void add_image ( Texture2D image, int width=0, int height=0, Color color=Color(1, 1, 1, 1), InlineAlignment inline_align=5, Rect2 region=Rect2(0, 0, 0, 0) )

Adds an image's opening and closing tags to the tag stack, optionally providing a width and height to resize the image, a color to tint the image and a region to only use parts of the image.

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

If width and height are not set, but region is, the region's rect will be used.

void add_text ( String text )

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

void append_text ( String bbcode )

Parses bbcode and adds tags to the tag stack as needed.

Note: Using this method, you can't close a tag that was opened in a previous append_text 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 text instead of using append_text.

void clear ( )

Clears the tag stack and sets text to an empty string.

void deselect ( )

Clears the current selection.

int get_character_line ( int character )

Returns the line number of the character position provided.

Note: If threaded is enabled, this method returns a value for the loaded part of the document. Use is_ready or finished to determine whether document is fully loaded.

int get_character_paragraph ( int character )

Returns the paragraph number of the character position provided.

Note: If
