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)

|
||||
.PP
|
||||
A class which draws a scale inside the plot canvas\&.
|
||||
|
||||
\fBQwtPlotScaleItem\fP can be used to draw an axis inside the plot canvas\&. It might by synchronized to one of the axis of the plot, but can also display its own ticks and labels\&.
|
||||
.PP
|
||||
It is allowed to synchronize the scale item with a disabled axis\&. In plots with vertical and horizontal scale items, it might be necessary to remove ticks at the intersections, by overloading \fBupdateScaleDiv()\fP\&.
|
||||
.PP
|
||||
The scale might be at a specific position (f\&.e 0\&.0) or it might be aligned to a canvas border\&.
|
||||
.PP
|
||||
\fBExample\fP
|
||||
.RS 4
|
||||
The following example shows how to replace the left axis, by a scale item at the x position 0\&.0\&.
|
||||
.PP
|
||||
.nf
|
||||
QwtPlotScaleItem *scaleItem = new QwtPlotScaleItem( QwtScaleDraw::RightScale, 0\&.0 );
|
||||
scaleItem->setFont( plot->axisWidget( QwtPlot::yLeft )->font() );
|
||||
scaleItem->attach(plot);
|
||||

||||
plot->enableAxis( QwtPlot::yLeft, false );
