- 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)

Abstract interface for iterating over samples\&.
|
|
|
|
Qwt offers several implementations of the \fBQwtSeriesData\fP API, but in situations, where data of an application specific format needs to be displayed, without having to copy it, it is recommended to implement an individual data access\&.
|
|
.PP
|
|
A subclass of \fBQwtSeriesData<QPointF>\fP must implement:
|
|
.PP
|
|
.IP "\(bu" 2
|
|
\fBsize()\fP
|
|
.br
|
|
Should return number of data points\&.
|
|
.IP "\(bu" 2
|
|
\fBsample()\fP
|
|
.br
|
|
Should return values x and y values of the sample at specific position as QPointF object\&.
|
|
.IP "\(bu" 2
|
|
\fBboundingRect()\fP
|
|
.br
|
|
Should return the bounding rectangle of the data series\&. It is used for autoscaling and might help certain algorithms for displaying the data\&. You can use qwtBoundingRect() for an implementation but often it is possible to implement a more efficient algorithm depending on the characteristics of the series\&. The member d_boundingRect is intended for caching the calculated rectangle\&.

Calculate the bounding rect of all samples
|
|
.PP
|
|
The bounding rect is necessary for autoscaling and can be used for a couple of painting optimizations\&.
|
|
.PP
|
|
qwtBoundingRect(\&.\&.\&.) offers slow implementations iterating over the samples\&. For large sets it is recommended to implement something faster f\&.e\&. by caching the bounding rectangle\&.
