Gtk.TextBuffer.prototype.delete

function delete(start:Gtk.TextIter, end:Gtk.TextIter):void {
    // Gjs wrapper for gtk_text_buffer_delete()
}

Deletes text between start and end. The order of start and end is not actually relevant; Gtk.TextBuffer.prototype.delete will reorder them. This function actually emits the "delete-range" signal, and the default handler of that signal deletes the text. Because the buffer is modified, all outstanding iterators become invalid after calling this function; however, the start and end will be re-initialized to point to the location where text was deleted.
