Property Events

X associates properties with windows. These are basically key-value pairs used for interclient communication; most commonly, they relay some information about a toplevel window to the window manager. GTK+ provides a high-level interface for all the important properties, so you should not need to deal with them directly. Property events are sent when a property's value changes.
