Qt5 built in qwt (#570)
- 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 Base class for items on the plot canvas
|
||||
|
||||
A plot item is "something", that can be painted on the plot canvas,
|
||||
or only affects the scales of the plot widget. They can be categorized as:
|
||||
|
||||
- Representator\n
|
||||
A "Representator" is an item that represents some sort of data
|
||||
on the plot canvas. The different representator classes are organized
|
||||
according to the characteristics of the data:
|
||||
- QwtPlotMarker
|
||||
Represents a point or a horizontal/vertical coordinate
|
||||
- QwtPlotCurve
|
||||
Represents a series of points
|
||||
- QwtPlotSpectrogram ( QwtPlotRasterItem )
|
||||
Represents raster data
|
||||
- ...
|
||||
|
||||
- Decorators\n
|
||||
A "Decorator" is an item, that displays additional information, that
|
||||
is not related to any data:
|
||||
- QwtPlotGrid
|
||||
- QwtPlotScaleItem
|
||||
- QwtPlotSvgItem
|
||||
- ...
|
||||
|
||||
Depending on the QwtPlotItem::ItemAttribute flags, an item is included
|
||||
into autoscaling or has an entry on the legend.
|
||||
|
||||
Before misusing the existing item classes it might be better to
|
||||
implement a new type of plot item
|
||||
( don't implement a watermark as spectrogram ).
|
||||
Deriving a new type of QwtPlotItem primarily means to implement
|
||||
the YourPlotItem::draw() method.
|
||||
|
||||
\sa The cpuplot example shows the implementation of additional plot items.
