Introduction
GtkCheckButton widgets serve the exact same purpose as GtkToggleButtons except that they look differently. Instead of looking like a normal button, GtkCheckButton widgets appear as small check boxes. GtkCheckButton widgets are usually used next to GtkLabels that describe what the option is. Instead of declaring a GtkCheckButton and a GtkLabel and placing them next to each other, a shortcut is to use the gtk_check_button_new_with_label function, which allows you to create the check button and the label in one statement.
