<brief_description>
|
|
Label that displays rich text.
|
|
</brief_description>
|
|
<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.
|
|
[b]Note:[/b] Assignments to [member bbcode_text] clear the tag stack and reconstruct it from the property's contents. Any edits made to [member bbcode_text] will erase previous edits made from other manual sources such as [method append_bbcode] and the [code]push_*[/code] / [method pop] methods.
|
|
[b]Note:[/b] RichTextLabel doesn't support entangled BBCode tags. For example, instead of using [code][b]bold[i]bold italic[/b]italic[/i][/code], use [code][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][center][/code] tag as follows: [code][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_height] property.
|
|
[b]Note:[/b] Unicode characters after [code]0xffff[/code] (such as most emoji) are [i]not[/i] supported on Windows. They will display as unknown characters instead. This will be resolved in Godot 4.0.

<argument index="2" name="height" type="int" default="0" />
|

<description>
|
|
Adds an image's opening and closing tags to the tag stack, optionally providing a [code]width[/code] and [code]height[/code] to resize the image.
|
|
If [code]width[/code] or [code]height[/code] is set to 0, the image size will be adjusted in order to keep the original aspect ratio.

<return type="void" />

<method name="append_bbcode">
|
|
<return type="int" enum="Error" />
|

<argument index="0" name="bbcode" type="String" />
|
|
<description>
|
|
Parses [code]bbcode[/code] and adds tags to the tag stack as needed. Returns the result of the parsing, [constant OK] if successful.
|
|
[b]Note:[/b] Using this method, you can't close a tag that was opened in a previous [method append_bbcode] 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 bbcode_text] instead of using [method append_bbcode].

If [code]true[/code], the label uses BBCode formatting.

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.

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