GtkSourceStyleScheme Object controlling apperance of #GtkSourceView #GtkSourceStyleScheme contains all the text styles to be used in #GtkSourceView and #GtkSourceBuffer. For instance, it contains text styles for syntax highlighting, it may contain foreground and background color for non-highlighted text, etc. Style schemes are stored in XML files. The format of scheme file is the following. The toplevel tag in a style scheme file is <style-scheme>. It has the following attributes: id (mandatory) Identifier for the style scheme. This is must be unique among style schemes. name (mandatory) Name of the style scheme. This is the name of the scheme to display to user, e.g. in a preferences dialog. _name This is the same as name attribute, except it will be translated. name and _name may not be used simultaneously. parent-scheme (optional) Style schemes may have parent schemes: all styles but those specified in the scheme will be taken from the parent scheme. In this way a scheme may be customized without copying all its content. version (mandatory) Style scheme format identifier. At the moment it must be "1.0". style-scheme tag may contain the following tags: author Name of the style scheme author. description Description of the style scheme. _description Same as description except it will be localized. color tags These define color names to be used in style tags. It has two attributes: name and value. value is the hexadecimal color specification like "#000000" or named color understood by Gdk prefixed with "#", e.g. "#beige". style tags See below for their format description. Each style tag describes a single element of style scheme (it corresponds to #GtkSourceStyle object). It has the following attributes: name (mandatory) Name of the style. It can be anything, syntax highlighting uses lang-id:style-id, and there are few special styles which are used to control general appearance of the text. Style scheme may contain other names to be used in an application. For instance, it may define color to highlight compilation errors in a build log or a color for bookmarks. foreground Foreground color. It may be name defined in one of color tags, or value in hexadecimal format, e.g. "#000000", or symbolic name understood by Gdk, prefixed with "#", e.g. "#magenta" or "#darkred". background Background color. italic "true" or "false" bold "true" or "false" underline "true" or "false" strikethrough "true" or "false" The following are names of styles which control #GtkSourceView appearance: text Default style of text. selection Style of selected text. selection-unfocused Style of selected text when the widget doesn't have input focus. cursor Text cursor style. Only foreground attribute is used for this style secondary-cursor Secondary cursor style (used in bidi text). Only foreground attribute is used for this style. If this is not set while "cursor" is, then a color between text background and cursor colors is chosen, so it is enough to use "cursor" style only. current-line Current line style. Only background attribute is used line-numbers Text and background colors for the left margin, on which line numbers are drawn bracket-match Style to use for matching brackets. bracket-mismatch Style to use for mismatching brackets. #GtkSourceStyle, #GtkSourceStyleManager GtkSourceStyleScheme structure contains only private members and should not be accessed directly. @scheme: @Returns: @scheme: @Returns: @scheme: @Returns: @scheme: @Returns: @scheme: @Returns: @scheme: @style_id: @Returns:
