RangeSelectorTool Class Reference

#include <RangeSelectorTool.h>

Inheritance diagram for RangeSelectorTool:

PlotToolInterface

List of all members.


Detailed Description

Plot tool for selecting ranges on curves.

As detailed in the documentation of PlotToolInterface, this one is different from most other plot tools in that other tools depend on it. Thus, either RangeSelectorTool should cease to inherit from PlotToolInterface and be renamed to RangeSelector, drawing a clear destinction to the other tools, or the notion of multiple tools being active in parallel and possibly depending on each other should be generalized somehow.

In any case, gathering the code specific to range selection in a seperate class makes Graph/CanvasPicker more manageable; maybe something similar can be done for zooming.
