- 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)

Format
|
|
.br
|
|
A text might include control sequences (f\&.e tags) describing how to render it\&. Each format (f\&.e MathML, TeX, Qt Rich Text) has its own set of control sequences, that can be handles by a special \fBQwtTextEngine\fP for this format\&.
|
|
.IP "\(bu" 2
|
|
Background
|
|
.br
|
|
A text might have a background, defined by a QPen and QBrush to improve its visibility\&. The corners of the background might be rounded\&.
|
|
.IP "\(bu" 2
|
|
Font
|
|
.br

Paint Attributes\&. Font and color and background are optional attributes of a \fBQwtText\fP\&. The paint attributes hold the information, if they are set\&.

|
\fB\fIMathMLText \fP\fP
|
|
Use a MathML (http://en.wikipedia.org/wiki/MathML) render engine to display the text\&. The Qwt MathML extension offers such an engine based on the MathML renderer of the former Qt solutions package\&. To enable MathML support the following code needs to be added to the application:
|
|
.PP
|
|
.PP
|
|
.nf
|
|
QwtText::setTextEngine( QwtText::MathMLText, new QwtMathMLTextEngine() );

Use a TeX (http://en.wikipedia.org/wiki/TeX) render engine to display the text ( not implemented yet )\&.
|
|
.TP
|
|
\fB\fIOtherFormat \fP\fP
|
|
The number of text formats can be extended using setTextEngine\&. Formats >= \fBQwtText::OtherFormat\fP are not used by Qwt\&.
