+// PollKey polls for a pressed key.

+// It returns the code of the pressed key or -1 if no key was pressed since

+//
+// The functions waitKey and pollKey are the only methods in HighGUI that can
+// fetch and handle GUI events, so one of them needs to be called periodically
+// for normal event processing unless HighGUI is used within an environment that
+// takes care of event processing.
+// The function only works if there is at least one HighGUI window created and
+// the window is active. If there are several HighGUI windows, any of them can
+// be active.
