Re: [Discuss-gnuradio] Need an "indicator" on the GUI display

[Isdren Gineer]

If you build a wx.App application you can use wx.StaticBitmap indicators for each channel. The bitmap for each channel can then be SetBitmap() to either a red or green circle, for example, depending on whether the power exceeds a threshold. The power measurements and threshold checks can be performed in a loop/sleep thread. Multithreading with gui applications can have issues so be sure to use wx.MutexGuiEnter() before the SetBitmap call and wx.MutexGuiLeave() after.

Hi Jim,

you can easily code your own GUI ;). Actually, I find that streaming values via UDP or TCP to a remote python application works rather nicely.
And I find that gygtk and pycairo are rather powerful toolsets.
Also I fiddled around with different python web frameworks, taking data from a socket, and "rendering" it by updating a browser page using ajax, but I kind of lost interest on the way... But maybe this might be of interest to your application case.

Greetings,

YOu can stick a PROBE in the path, and have a static-text box take the output of a variable that tells you whether threshold exceeded or not.
  It's not a "lamp", but it does the job.
