Signals

  • meta_clicked ( Nil meta )

Triggered when the user clicks on content between url 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 ( Nil meta )

Triggers when the mouse exits a meta tag.

  • meta_hover_started ( Nil meta )

Triggers when the mouse enters a meta tag.

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

Property Descriptions

  • bool bbcode_enabled
Setter set_use_bbcode(value)
Getter is_using_bbcode()

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

Setter set_bbcode(value)
Getter get_bbcode()

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.

  • bool meta_underlined
Setter set_meta_underline(value)
Getter is_meta_underlined()

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

  • bool override_selected_font_color
Setter set_override_selected_font_color(value)
Getter is_overriding_selected_font_color()

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

Setter set_percent_visible(value)
Getter get_percent_visible()

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

  • bool scroll_active
Setter set_scroll_active(value)
Getter is_scroll_active()

If true, the scrollbar is visible. Does not block scrolling completely. See scroll_to_line. Default value: true.

  • bool scroll_following
Setter set_scroll_follow(value)
Getter is_scroll_following()

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

  • bool selection_enabled
Setter set_selection_enabled(value)
Getter is_selection_enabled()

If true, the label allows text selection.

Setter set_tab_size(value)
Getter get_tab_size()

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

Setter set_text(value)
Getter get_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.

  • int visible_characters
Setter set_visible_characters(value)
Getter get_visible_characters()

The restricted number of characters to display in the label.

Method Descriptions

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.

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

  • void clear ( )

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

  • int 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.

  • int get_total_character_count ( ) const

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

Returns the vertical scrollbar.

  • int get_visible_line_count ( ) const

Returns the number of visible lines.

  • void newline ( )

Adds a newline tag to the tag stack.

The assignment version of append_bbcode. Clears the tag stack and inserts the new content. Returns OK 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 a [right] tag to the tag stack.

  • 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 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 ( int level )

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

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

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

  • void push_table ( int columns )

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

  • void push_underline ( )

Adds a [u] tag to the tag stack.

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

  • void scroll_to_line ( int line )

Scrolls the window’s top line to match line.

  • void set_table_column_expand ( int column, bool 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.

For example, 2 columns with ratios 3 and 4 plus 70 pixels in available width would expand 30 and 40 pixels, respectively.

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