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)

A plot item, which displays a text label\&.
|

|

\fBQwtPlotTextLabel\fP displays a text label aligned to the plot canvas\&.
|
||||
.PP
|
||||
In opposite to \fBQwtPlotMarker\fP the position of the label is unrelated to plot coordinates\&.
|
||||
.PP
|
||||
As drawing a text is an expensive operation the label is cached in a pixmap to speed up replots\&.

.RS 4
|

The following code shows how to add a title\&.

title\&.setRenderFlags( Qt::AlignHCenter | Qt::AlignTop );
