Label that displays rich text.

Properties

Methods

Signals

• meta_clicked ( meta )

Triggered when the user clicks on content between 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 method must be used to manually insert the data into the tag stack.

• meta_hover_ended ( Nil meta )

Triggers when the mouse exits a meta tag.

• meta_hover_started ( meta )

Triggers when the mouse enters a meta tag.

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 that assignments to bbcode_text clear the tag stack and reconstruct it from the property’s contents. Any edits made to will erase previous edits made from other manual sources such as append_bbcode and the push_* / methods.

Property Descriptions

• bbcode_enabled

If true, the label uses BBCode formatting. Default value: false.

• String bbcode_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.

• meta_underlined

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

• bool override_selected_font_color

If true, the label uses the custom font color. Default value: false.

• percent_visible

The text’s visibility, as a float between 0.0 and 1.0.

• scroll_active

• bool scroll_following

If , the window scrolls down to display new content automatically. Default value: false.

• selection_enabled

If true, the label allows text selection.

• int tab_size

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

• text

The raw text of the label.

When set, clears the tag stack and adds a raw text tag to the top of it. Does not parse bbcodes. Does not modify bbcode_text.

• visible_characters

The restricted number of characters to display in the label.

Adds an image’s opening and closing tags to the tag stack.

• void add_text ( String text )

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

• append_bbcode ( String bbcode )

Parses bbcode and adds tags to the tag stack as needed. Returns the result of the parsing, if successful.

• void clear ( )

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

• get_content_height ( )

Returns the height of the content.

• int get_line_count ( ) const

Returns the total number of newlines in the tag stack’s text tags. Considers wrapped text as one line.

• get_total_character_count ( ) const

Returns the total number of characters from text tags. Does not include bbcodes.

• VScrollBar get_v_scroll ( )

Returns the vertical scrollbar.

• get_visible_line_count ( ) const

Returns the number of visible lines.

• void newline ( )

• Error parse_bbcode ( bbcode )

The assignment version of append_bbcode. Clears the tag stack and inserts the new content. Returns if parses bbcode successfully.

• void pop ( )

Terminates the current tag. Use after push_* methods to close bbcodes manually. Does not need to follow add_* methods.

• void push_align ( Align align )

Adds an alignment tag based on the given align value. See for possible values.

• void push_cell ( )

Adds a [cell] tag to the tag stack. Must be inside a [table] tag. See push_table for details.

• void push_color ( color )

Adds a [color] tag to the tag stack.

• void push_font ( Font font )

Adds a [font] tag to the tag stack. Overrides default fonts for its duration.

• void push_indent ( level )

Adds an tag to the tag stack. Multiplies “level” by current tab_size to determine new margin length.

• void push_list ( ListType type )

Adds a list tag to the tag stack. Similar to the bbcodes [ol] or [ul], but supports more list types. Not fully implemented!

• void push_meta ( data )

Adds a meta tag to the tag stack. Similar to the bbcode [url=something]{text}[/url], but supports non-String metadata types.

• void push_strikethrough ( )

Adds a [s] tag to the tag stack.

• void push_table ( columns )

Adds a [table=columns] tag to the tag stack.

• void push_underline ( )

Adds a [u] tag to the tag stack.

• bool remove_line ( line )

Removes a line of content from the label. Returns true if the line exists.

Scrolls the window’s top line to match line.

• void set_table_column_expand ( int column, expand, int ratio )

Edits the selected columns expansion options. If expand is true, the column expands in proportion to its expansion ratio versus the other columns’ ratios.

Columns with a false expand will not contribute to the total ratio.
