- 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 spectrogram\&.
|
|
|
|
A spectrogram displays 3-dimensional data, where the 3rd dimension ( the intensity ) is displayed using colors\&. The colors are calculated from the values using a color map\&.
|
|
.PP
|
|
On multi-core systems the performance of the image composition can often be improved by dividing the area into tiles - each of them rendered in a different thread ( see \fBQwtPlotItem::setRenderThreadCount()\fP )\&.
|

|

In ContourMode contour lines are painted for the contour levels\&.

In Qt5 the default pen width is 1\&.0 ( 0\&.0 in Qt4 ) what makes it non cosmetic ( see QPen::isCosmetic() )\&. This method has been introduced to hide this incompatibility\&.
