A control for displaying text that can contain different font styles, images, and basic formatting.
</brief_description>
<description>
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.
[b]Note:[/b] Assignments to [member text] clear the tag stack and reconstruct it from the property's contents. Any edits made to [member text] will erase previous edits made from other manual sources such as [method append_text] and the [code]push_*[/code] / [method pop] methods.
[b]Note:[/b] RichTextLabel doesn't support entangled BBCode tags. For example, instead of using [code skip-lint][b]bold[i]bold italic[/b]italic[/i][/code], use [code skip-lint][b]bold[i]bold italic[/i][/b][i]italic[/i][/code].
[b]Note:[/b] [code]push_*/pop_*[/code] functions won't affect BBCode.
[b]Note:[/b] Unlike [Label], [RichTextLabel] doesn't have a [i]property[/i] to horizontally align text to the center. Instead, enable [member bbcode_enabled] and surround the text in a [code skip-lint][center][/code] tag as follows: [code skip-lint][center]Example[/center][/code]. There is currently no built-in way to vertically align text either, but this can be emulated by relying on anchors/containers and the [member fit_content] property.

<method name="add_image">
<return type="void" />
<param index="0" name="image" type="Texture2D" />
<param index="1" name="width" type="int" default="0" />
<param index="2" name="height" type="int" default="0" />

<param index="7" name="pad" type="bool" default="false" />
<param index="8" name="tooltip" type="String" default="&quot;&quot;" />
<param index="9" name="size_in_percent" type="bool" default="false" />
<description>
Adds an image's opening and closing tags to the tag stack, optionally providing a [param width] and [param height] to resize the image, a [param color] to tint the image and a [param region] to only use parts of the image.
If [param width] or [param height] is set to 0, the image size will be adjusted in order to keep the original aspect ratio.
If [param width] and [param height] are not set, but [param region] is, the region's rect will be used.
[param key] is an optional identifier, that can be used to modify the image via [method update_image].
If [param pad] is set, and the image is smaller than the size specified by [param width] and [param height], the image padding is added to match the size instead of upscaling.
If [param size_in_percent] is set, [param width] and [param height] values are percentages of the control width instead of pixels.

</method>
<method name="add_text">
<return type="void" />
<param index="0" name="text" type="String" />
<description>
Adds raw non-BBCode-parsed text to the tag stack.
</description>
</method>
<method name="append_text">
<return type="void" />
<param index="0" name="bbcode" type="String" />
<description>
Parses [param bbcode] and adds tags to the tag stack as needed.
[b]Note:[/b] Using this method, you can't close a tag that was opened in a previous [method 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 [member text] instead of using [method append_text].
</description>
</method>
<method name="clear">
<return type="void" />
<description>
Clears the tag stack, causing the label to display nothing.
[b]Note:[/b] This method does not affect [member text], and its contents will show again if the label is redrawn. However, setting [member text] to an empty [String] also clears the stack.

<signals>
<signal name="finished">
<description>
Triggered when the document is fully loaded.
</description>
</signal>
<signal name="meta_clicked">
<param index="0" name="meta" type="Variant" />
<description>
Triggered when the user clicks on content between meta (URL) tags. If the meta is defined in BBCode, e.g. [code skip-lint][url={"key": "value"}]Text[/url][/code], then the parameter for this signal will always be a [String] type. If a particular type or an object is desired, the [method 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 [method JSON.parse] on it).
For example, the following method can be connected to [signal meta_clicked] to open clicked URLs using the user's default web browser:
[codeblocks]
[gdscript]
# 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))
[/gdscript]
[/codeblocks]
</description>
</signal>
<signal name="meta_hover_ended">
<param index="0" name="meta" type="Variant" />
<description>
Triggers when the mouse exits a meta tag.

<signal name="meta_hover_started">
