|See also: MouseAction, ClearMouseTrace, MouseTraceColor, MouseTraceInvert|
TGeoMap provides a means for displaying and recording the mouse trace when the left button is pressed. In order to activate this feature the MouseAction property has to be set to maDrawMTrace and the property AutoRedraw to FALSE.
The read-only array property MouseTrace returns the mouse trace points recorded since the last call to ClearMouseTrace. The parameter idx is the index of the trace (valid range between 1 and NumMTracePoints).
