Aha! The middle menu button click works after all :-) Thank you very
much for your help everyone!
I was able to get the middle button click functionality to work in the
individual sinks (QT GUI Time Sink, QT GUI Frequency Sink, QT GUI
Constellation Sink, and QT GUI Waterfall Sink) however, I was not able
to get the middle button menu functionality to work in the "master"
instrumentation block (QT GUI Sink). That may be an issue with my
installation of gnuradio; unsure.
Per your suggestion I'll look over the manual page and see what I can do
to help; thank you so much for yours!

Greetings all,
I recently began using gnuradio and GRC with a pair of
USRPs. It's my understanding that plans are underway to ultimately
remove WX in v3.9 as a GUI option from gnuradio, and replace it
with QT. It's also my understanding that QT GUI development is
underway in future versions of gnuradio. I'm interested in
attempting to help develop for gnuradio and have forked a copy of
the source from github.
Adding a bit to what Marcus said.
With that in mind, I have a few questions:
1. Who is involved with QT GUI development for gnuradio?
Mostly, but not solely, me. More people working on this feature would
be nice.
1. What future improvements, especially functionality
related, are planned for gnuradio QT? All I have been able
to find in the 3.8.0 roadmap is that grc will "introduce a
QT version of GRC" (what does that mean?) and that
gr-qtgui will be switching examples to use gr-qtgui
instead of gr-wxgui. Functionality I'm most interested in
includes X/Y mode for the QT GUI Time Sink and the ability
to pause the output of the Time, Frequency, and Waterfall
sinks (as is available via the "Stop" button in the WX
counterparts.
We have plans to discuss the features we need next week at our
hackfest. There are really two that come to mind that need attention.
The first is a strip-chart feature of the time plots (instead of
waiting for a full number of samples, this would plot any new samples
immediately and move the graph to the right -- used for slow signals
mainly). The second is a persistence mode in the time plots.
The X/Y mode would be nice, sure, but it's basically what the
Constellation plot does.
And we have already switched all GNU Radio example to QT instead of
WX. That happened a while ago, but I guess that info still persists on
the wiki (which page? It should be amended).
As Marcus pointed out, click the middle mouse button (or whatever's
equivalent button 3 on your system). That menu has most of the
instrumentation that's available in WX, just as a menu instead of the
instrumentation panel. Including the ability to stop and save images.
1. In looking over the WX and QT GUI options, I personally
prefer the layout and functionality of the WX GUI
components (specifically, the instrumentation options).
Are there any plans to attempt to replicate the layout and
options of the WX components? (Perhaps the old WX layout
style and functionality are being abandoned for good
reason; if that's the case, if anybody could clarify that
for me or point me in the right direction I would be most
appreciative.)
Thanks everyone, and I look forward to hearing from you!

I don't like the instrumentation panel in WX. It's clunky and doesn't
scale well. And it takes up a lot of screen real estate that could be
used for looking at the signals. However, I know that a lot of people
like it for quick access to some of the features. As I said, it's all
available in the drop-down menu, but it can take a few clicks to get
to the right thing.
I'm actually working on this now. Something to hack on while at ELC,
basically. My main goal with it, though, is that I want a button or
trigger to hide the panel, so you can open it up or close it depending
on what you are doing or trying to see. But really, this is just
adding QT widgets to do what's already available in the menus, so
nothing really "new" just, hopefully, more user friendly.
One thing that would be really appreciated is if you want to look over
the manual page and make suggestions and add material to make it more
clear to people what the capabilities are and how to use them.

And we'll probably have more to-do's next week when we chat about this
at the hackfest.
Thanks for your interest.
Tom
