ScientificPlotEvent Class Reference

Description

Helps ScientificPlot to handle mouse events. Particularly, it constructs a valid status string. Can be extended to play a role of event filter.

void	onCustomMouseMove (QMouseEvent *event)
	Constructs status string on mouse move event coming from QCustomPlot. String is emitted if mouse is in axes's viewport rectangle. Once mouse goes out of it, an empty string is emitted once again. More...
