Hello ROOTers

I am now trying to modify exec1.C in $ROOT/tutorials to
calculate distance two points along x-axis of my histogram.
The two points are pushed and released by mouse, respectively.

I succeeded in knowing pushed points and released points
using return values of gPad->GetEvent()(kButton1Down and kButton1Up).

But, the distance between two points could not be obtained.

So, is there the way to get the distance of the two points ?
