The new GRC theme system using qss files looks pretty neat and seems very
user configurable. Thanks.
To use this, with my build-gnuradio installed setup, I had to create a new
file under my home user folder at /home/me/.gnuradio/config.conf and I had
to add the following to that file.
[QTGUI]
qss = /usr/local/share/gnuradio/themes/alt.qss
To go back to the normal theme I just commented out that line, like so...
[QTGUI]
#qss = /usr/local/share/gnuradio/themes/alt.qss
All this works just fine.
*BUT*
I did run into one issue using this with a QT GUI Constellation Sink.
The constellation points have the lines turned on running between them (ie
so they look like a transition diagram instead of what I think of as a
constellation diagram).
So before I asked for help here I thought I'd have some fun with it and
tried some stuff on my own.
I tried adding the following to the alt.qss file in my
/usr/local/share/gnuradio/themes folder (had to change file permissions on
the qss files to do this with my editor - but I am guessing the permissions
change is not an issue).
ConstellationDisplayPlot {
qproperty-line_style1: None;
qproperty-line_style2: None;
qproperty-line_style3: None;
}
I put this between the VectorDIsplayPlot entries and the QwtPlotCanvas
entries.
I also tried replacing the similar lines in DisplayPlot with the selections
for "None" I show above.
None of that changed the constellation to remove the lines between points.
To make sure I was having 'some' effect, I tried making the background for
the whole plot an ugly green color (changing the top QWidget
background-color) and that worked, so I am at least affecting something
with that file if I had the syntax and context correct.
I did the requesite Google search on "QtCore.Qt.DashLine" to see if there
was a syntax aside from "None" that would be correct, but while I could
find syntax for several other line choices I did not a find syntax for a
choice for no line. So it is possible the issue is deeper than just a qss
configuration line.
*SO*
Any idea how to make the QT constellation plots not have the transition
lines between points when using one of the qss sheets?
Thanks,
- John
