+Returns the number of mouse clicks for this event: $1$ for a simple click, $2$
+for a double-click, $3$ for a triple-click and so on.
+
+Currently this function is implemented only in wxMac and returns $-1$ for the
+other platforms (you can still distinguish simple clicks from double-clicks as
+they generate different kinds of events however).
