Detailed Description

A QgsPlotMouseEvent is the result of a user interaction with the mouse on a QgsPlotCanvas.

The event is sent whenever the user moves, clicks, releases or double clicks the mouse.

In addition to the coordinates in pixel space the event may have knowledge about geographic coordinates corresponding to the event.
