Re: [Discuss-gnuradio] qt_gui_time

Thanks everyone for the replies. Huge help.

Kudos to Marcus Leech for the suggestion. Seems to work wonderfully. At least in my test GRC file. Now to implement into my own program.

Cheers!

Hi Wayne, Hi Joe,

you're right – we've been urging people to switch away from WX since at
least 2014, and now we're finally removing it; with a bit of a heavy
heart, to be honest: Without feature equality, removing an alternative
feels bad, but we simply couldn't maintain the WX code anymore, and had
to find the resources to maintain QT stuff first.
So, no, we don't have that specific visualization in Qt, sorry. Joe,
this means we've long stopped supporting your widget – it works on most
machines, on others it doesn't, and we can't really help you in the
latter case.

Now, would one get started with developing a strip chart for Qt? Either
one cheats a bit and just implements something that hands n_points
sized chunks of data to the Qt GUI time sink, which always are
basically the last chunk, with old samples "shifted out" and new
samples "shifted in", or one would actually go and do a deep C++/Qt
dive and write a proper stripchart widget.

Best regards,
Marcus
