- qt4->qt5 - in built qt5 6.1.5 because rhel7 is not upto date with qt5, removed findqwt.cmake - made a fix in qwt lib (qwt_plot_layout.h) to work with 5.15 and lower versions for qrect constr. - qt5 forms fixed, qt4 many hard coding forms switched to forms including qtabwidget, scrolls etc, fonts moved to forms - docking option enabled by default, removed option to disable docking feature from "Mode" - added qVersionResolve utility functions to handle compatibility before and after qt5.12 - qtplots (ian's code) takes in gain mode enable to set some settings within the class, with proper gain plot ticks - ensure gain plots have no zooming of z axis in 2d and y axis in 1d - removed placeholder text in qpalette in main window form as its not supportd until 5.12 (so using qt5.9 designer insted of qt5.15 to cope) - tab order Servers: - fixed some error messages that were empty for fail in funcs (mostly minor as if this error, major issues)

\brief A class for spline interpolation
|
|
|
|
The QwtSpline class is used for cubical spline interpolation.
|
|
Two types of splines, natural and periodic, are supported.
|
|
|
|
\par Usage:
|
|
<ol>
|
|
<li>First call setPoints() to determine the spline coefficients
|
|
for a tabulated function y(x).
|
|
<li>After the coefficients have been set up, the interpolated
|
|
function value for an argument x can be determined by calling
|
|
QwtSpline::value().
|
|
</ol>
|
|
|
|
\par Example:
|
|
\code
|
|
#include <qwt_spline.h>
|
|
|
|
QPolygonF interpolate(const QPolygonF& points, int numValues)
|
|
{
|
|
QwtSpline spline;
|
|
if ( !spline.setPoints(points) )
|
|
return points;
|
|
|
|
QPolygonF interpolatedPoints(numValues);
|
|
|
|
const double delta =
|
|
(points[numPoints - 1].x() - points[0].x()) / (points.size() - 1);
|
|
for(i = 0; i < points.size(); i++) / interpolate
|
|
{
|
|
const double x = points[0].x() + i * delta;
|
|
interpolatedPoints[i].setX(x);
|
|
interpolatedPoints[i].setY(spline.value(x));
|
|
}
|
|
return interpolatedPoints;
|
|
}
|
|
\endcode
