Mark
Mark object for class@Buffer.
A GtkSourceMark
marks a position in the text where you want to display additional info. It is based on class@Gtk.TextMark and thus is still valid after the text has changed though its position may change.
GtkSourceMark
s are organized in categories which you have to set when you create the mark. Each category can have a priority, a pixbuf and other associated attributes. See method@View.set_mark_attributes. The pixbuf will be displayed in the margin at the line where the mark residents if the property@View:show-line-marks property is set to true. If there are multiple marks in the same line, the pixbufs will be drawn on top of each other. The mark with the highest priority will be drawn on top.
