KCurve Class Reference

#include <kcurve.h>

List of all members.


Detailed Description

KCurve is a widget that shows a single curve that can be edited by the user. The user can grab the curve and move it; this creates a new control point. Control points can be deleted by selecting a point and pressing the delete key.

(From: http://techbase.kde.org/Projects/Widgets_and_Classes#KCurve) KCurve allows editing of spline based y=f(x) curves. Handy for cases where you want the user to control such things as tablet pressure response, color transformations, acceleration by time, aeroplane lift by angle of attack.
