Inherits: Control < CanvasItem < Node < Object
A control for displaying text that can contain different font styles, images, and basic formatting.
A control for displaying text that can contain custom fonts, images, and basic formatting. RichTextLabel 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.

Triggered when the document is fully loaded.
Triggered when the user clicks on content between meta (URL) tags. If the meta is defined in BBCode, e.g. [url={"key": "value"}]Text[/url], then the parameter for this signal will always 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. Alternatively, you can convert the String input to the desired type based on its contents (such as calling JSON.parse on it).
For example, the following method can be connected to meta_clicked to open clicked URLs using the user's default web browser:
# This assumes RichTextLabel's `meta_clicked` signal was connected to
# the function below using the signal connection dialog.
func _richtextlabel_on_meta_clicked(meta):
# `meta` is of Variant type, so convert it to a String to avoid script errors at run-time.
OS.shell_open(str(meta))
Triggers when the mouse exits a meta tag.
Triggers when the mouse enters a meta tag.

If this bit is set, update_image changes image texture.
2
If this bit is set, update_image changes image size.
4
If this bit is set, update_image changes image color.
8

64
If this bit is set, update_image changes image tooltip.
128
If this bit is set, update_image changes image width from/to percents.
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.
false
If true, the label uses BBCode formatting.
false
If true, a right-click displays the context menu.
[]
The currently installed custom effects. This is an array of RichTextEffects.
To add a custom effect, it's more convenient to use install_effect.
true
If true, the selected text will be deselected when focus is lost.
true
If true, allow drag and drop of selected text.
false
If true, the label's minimum size will be automatically updated to fit its content, matching the behavior of Label.
true
If true, the label underlines hint tags such as [hint=description]{text}[/hint].
""
Language code used for line-breaking and text shaping algorithms, if left empty current locale is used instead.
true
If true, the label underlines meta tags such as [url]{text}[/url]. These tags can call a function when clicked if meta_clicked is connected to a function.
1000
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.
true
If true, the scrollbar is visible. Setting this to false does not block scrolling completely. See scroll_to_line.
false
If true, the window scrolls down to display new content automatically.
false
If true, the label allows text selection.
true
If true, shortcut keys for context menu items are enabled, even if the context menu is disabled.
0
Set BiDi algorithm override for the structured text.
[]
Set additional options for BiDi override.
4
The number of spaces associated with a single tab length. Does not affect \t in text tags, only indent tags.
""
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.
0
Base text writing direction.
false
If true, text processing is done in a background thread.
-1
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.
0
Sets the clipping behavior when visible_characters or visible_ratio is set. See VisibleCharactersBehavior for more info.
1.0
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.
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.
key is an optional identifier, that can be used to modify the image via update_image.
If pad is set, and the image is smaller than the size specified by width and height, the image padding is added to match the size instead of upscaling.
If size_in_percent is set, width and height values are percentages of the control width instead of pixels.
Adds raw non-BBCode-parsed text to the tag stack.
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.
Clears the tag stack.
Note: This method will not modify text, but setting text to an empty string also clears the stack.
Clears the current selection.
Returns the line number of the character position provided. Line and character numbers are both zero-indexed.
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.
Returns the paragraph number of the character position provided. Paragraph and character numbers are both zero-indexed.
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.
Returns the height of the content.
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.
Returns the width of the content.
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.
Returns the total number of lines in the text. Wrapped text is counted as multiple lines.
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.
Returns the vertical offset of the line found at the provided index.
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.
Returns the PopupMenu of this RichTextLabel. By default, this menu is displayed when right-clicking on the RichTextLabel.
You can add custom menu items or remove standard ones. Make sure your IDs don't conflict with the standard ones (see MenuItems). For example:
func _ready():
var menu = get_menu()
# Remove "Select All" item.
menu.remove_item(MENU_SELECT_ALL)
# Add custom items.
menu.add_separator()
menu.add_item("Duplicate Text", MENU_MAX + 1)
# Connect callback.
menu.id_pressed.connect(_on_item_pressed)
func _on_item_pressed(id):
if id == MENU_MAX + 1:
add_text("\n" + get_parsed_text())
C#public override void _Ready()
{
var menu = GetMenu();
// Remove "Select All" item.
menu.RemoveItem(RichTextLabel.MenuItems.SelectAll);
// Add custom items.
menu.AddSeparator();
menu.AddItem("Duplicate Text", RichTextLabel.MenuItems.Max + 1);
// Add event handler.
menu.IdPressed += OnItemPressed;
}
public void OnItemPressed(int id)
{
if (id == TextEdit.MenuItems.Max + 1)
{
AddText("\n" + GetParsedText());
}
}
Warning: This is a required internal node, removing and freeing it may cause a crash. If you wish to hide it or any of its children, use their Window.visible property.
Returns the total number of paragraphs (newlines or p tags in the tag stack's text tags). Considers wrapped text as one paragraph.
Returns the vertical offset of the paragraph found at the provided index.
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.
Returns the text without BBCode mark-up.
Returns the current selection text. Does not include BBCodes.
Returns the current selection first character index if a selection is active, -1 otherwise. Does not include BBCodes.
Returns the current selection last character index if a selection is active, -1 otherwise. Does not include BBCodes.
Returns the total number of characters from text tags. Does not include BBCodes.
Returns the vertical scrollbar.
Warning: This is a required internal node, removing and freeing it may cause a crash. If you wish to hide it or any of its children, use their CanvasItem.visible property.
Returns the number of visible lines.
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.
Returns the number of visible paragraphs. A paragraph is considered visible if at least one of its lines is visible.
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.
Installs a custom effect. This can also be done in the RichTextLabel inspector using the custom_effects property. effect should be a valid RichTextEffect.
Example RichTextEffect:
# effect.gd class_name MyCustomEffect extends RichTextEffect var bbcode = "my_custom_effect" # ...
Registering the above effect in RichTextLabel from script:
# rich_text_label.gd
extends RichTextLabel
func _ready():
install_effect(MyCustomEffect.new())
# Alternatively, if not using `class_name` in the script that extends RichTextEffect:
install_effect(preload("res://effect.gd").new())
Returns whether the menu is visible. Use this instead of get_menu().visible to improve performance (so the creation of the menu is avoided).
If threaded is enabled, returns true if the background thread has finished text processing, otherwise always return true.
Executes a given action as defined in the MenuItems enum.
Adds a newline tag to the tag stack.
The assignment version of append_text. Clears the tag stack and inserts the new content.
Parses BBCode parameter expressions into a dictionary.
Terminates the current tag. Use after push_* methods to close BBCodes manually. Does not need to follow add_* methods.
Terminates all tags opened by push_* methods.
Terminates tags opened after the last push_context call (including context marker), or all tags if there's no context marker on the stack.
Adds a [bgcolor] tag to the tag stack.
Adds a [font] tag with a bold font to the tag stack. This is the same as adding a [b] tag if not currently in a [i] tag.
Adds a [font] tag with a bold italics font to the tag stack.
Adds a [cell] tag to the tag stack. Must be inside a [table] tag. See push_table for details.
Adds a [color] tag to the tag stack.
Adds a context marker to the tag stack. See pop_context.
Adds a custom effect tag to the tag stack. The effect does not need to be in custom_effects. The environment is directly passed to the effect.

Adds a [fgcolor] tag to the tag stack.
Adds a [font] tag to the tag stack. Overrides default fonts for its duration.
Passing 0 to font_size will use the existing default font size.
Adds a [font_size] tag to the tag stack. Overrides default font size for its duration.
Adds a [hint] tag to the tag stack. Same as BBCode [hint=something]{text}[/hint].
Adds an [indent] tag to the tag stack. Multiplies level by current tab_size to determine new margin length.

Adds language code used for text shaping algorithm and Open-Type font features.
Adds [ol] or [ul] tag to the tag stack. Multiplies level by current tab_size to determine new margin length.
Adds a meta tag to the tag stack. Similar to the BBCode [url=something]{text}[/url], but supports non-String metadata types.
Note: Meta tags do nothing by default when clicked. To assign behavior when clicked, connect meta_clicked to a function that is called when the meta tag is clicked.
Adds a [font] tag with a monospace font to the tag stack.
Adds a [font] tag with a normal font to the tag stack.
Adds a [outline_color] tag to the tag stack. Adds text outline for its duration.

Adds a [table=columns,inline_align] tag to the tag stack.
Adds a [u] tag to the tag stack.
Removes a paragraph of content from the label. Returns true if the paragraph exists.
The paragraph argument is the index of the paragraph to remove, it can take values in the interval [0, get_paragraph_count() - 1].
Scrolls the window's top line to match line.
Scrolls the window's top line to match first line of the paragraph.
Scrolls to the beginning of the current selection.
Select all the text.
If selection_enabled is false, no selection will occur.
Sets color of a table cell border.
Sets inner padding of a table cell.
Sets color of a table cell. Separate colors for alternating rows can be specified.
Sets minimum and maximum size overrides for a table cell.
Edits the selected column's 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.
If expand is false, the column will not contribute to the total ratio.
Updates the existing images with the key key. Only properties specified by mask bits are updated. See add_image.
Color(1, 1, 1, 1)
The default text color.
Color(1, 1, 1, 1)
The default tint of text outline.
Color(0, 0, 0, 0)
The color of selected text, used when selection_enabled is true. If equal to Color(0, 0, 0, 0), it will be ignored.
Color(0, 0, 0, 0)
The color of the font's shadow.
Color(0.1, 0.1, 1, 0.8)
The color of the selection box.
Color(0, 0, 0, 0)
The default cell border color.
Color(0, 0, 0, 0)
The default background color for even rows.
Color(0, 0, 0, 0)
The default background color for odd rows.
0
The vertical space between lines.
0
The size of the text outline.
Note: If using a font with FontFile.multichannel_signed_distance_field enabled, its FontFile.msdf_pixel_range must be set to at least twice the value of outline_size for outline rendering to look correct. Otherwise, the outline may appear to be cut off earlier than intended.
1
The horizontal offset of the font's shadow.
1
The vertical offset of the font's shadow.
1
The size of the shadow outline.
3
The horizontal separation of elements in a table.

The font size used for bold text.
The font size used for bold italics text.
The font size used for italics text.
The font size used for monospace text.

The background used when the RichTextLabel is focused. The focus StyleBox is displayed over the base StyleBox, so a partially transparent StyleBox should be used to ensure the base StyleBox remains visible. A StyleBox that represents an outline or an underline works well for this purpose. To disable the focus visual effect, assign a StyleBoxEmpty resource. Note that disabling the focus visual effect will harm keyboard/controller navigation usability, so this is not recommended for accessibility reasons.
The normal background for the RichTextLabel.
