- 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)

.SH "Detailed Description"
|
|
.PP
|
|
A class for drawing scales\&.
|
|
|
|
\fBQwtScaleDraw\fP can be used to draw linear or logarithmic scales\&. A scale has a position, an alignment and a length, which can be specified \&. The labels can be rotated and aligned to the ticks using \fBsetLabelRotation()\fP and \fBsetLabelAlignment()\fP\&.
|
|
.PP
|
|
After a scale division has been specified as a \fBQwtScaleDiv\fP object using \fBQwtAbstractScaleDraw::setScaleDiv(const QwtScaleDiv &s)\fP, the scale can be drawn with the \fBQwtAbstractScaleDraw::draw()\fP member\&.

Change the label flags\&. Labels are aligned to the point tick length + spacing away from the backbone\&.
|

.PP
|

The alignment is relative to the orientation of the label text\&. In case of an flags of 0 the label will be aligned depending on the orientation of the scale:

The various alignments might be confusing\&. The alignment of the label is not the alignment of the scale and is not the alignment of the flags ( QwtText::flags() ) returned from \fBQwtAbstractScaleDraw::label()\fP\&.

Rotate all labels\&.

When changing the rotation, it might be necessary to adjust the label flags too\&. Finding a useful combination is often the result of try and error\&.
