- 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)

|
|
\fBQwtSystemClock\fP provides high resolution clock time functions\&.
|
|
|
|
Sometimes the resolution offered by QTime ( millisecond ) is not accurate enough for implementing time measurements ( f\&.e\&. sampling )\&. \fBQwtSystemClock\fP offers a subset of the QTime functionality using higher resolution timers ( if possible )\&.
|
|
.PP
|
|
Precision and time intervals are multiples of milliseconds (ms)\&.
|
|
.PP
|
|
( \fBQwtSystemClock\fP is obsolete since Qt 4\&.8 as QElapsedTimer offers the same precision )
|
|
.PP
|
|
\fBNote\fP
|
|
.RS 4
|
|
The implementation uses high-resolution performance counter on Windows, mach_absolute_time() on the Mac or POSIX timers on other systems\&. If none is available it falls back on QTimer\&.
