- 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 legend inside the plot canvas\&.
|
|
|
|
\fBQwtPlotLegendItem\fP can be used to draw a inside the plot canvas\&. It can be used together with a \fBQwtLegend\fP or instead of it to have more space for the plot canvas\&.
|
|
.PP
|
|
In opposite to \fBQwtLegend\fP the legend item is not interactive\&. To identify mouse clicks on a legend item an event filter needs to be installed catching mouse events ob the plot canvas\&. The geometries of the legend items are available using \fBlegendGeometries()\fP\&.
|
|
.PP
|
|
The legend item is aligned to plot canvas according to its \fBalignment()\fP flags\&. It might have a background for the complete legend ( usually semi transparent ) or for each legend item\&.
|
|
.PP
|
|
\fBNote\fP
|
|
.RS 4
|
|
An external \fBQwtLegend\fP with a transparent background on top the plot canvas might be another option with a similar effect\&.
