Gtk.TextMark.new

function new(name:String, left_gravity:Boolean):Gtk.TextMark {
    // Gjs wrapper for gtk_text_mark_new()
}

Creates a text mark. Add it to a buffer using Gtk.TextBuffer.prototype.add_mark. If name is null, the mark is anonymous; otherwise, the mark can be retrieved by name using Gtk.TextBuffer.prototype.get_mark. If a mark has left gravity, and text is inserted at the mark's current location, the mark will be moved to the left of the newly-inserted text. If the mark has right gravity (left_gravity = false), the mark will end up on the right of newly-inserted text. The standard left-to-right cursor is a mark with right gravity (when you type, the cursor stays on the right side of the text you're typing).
