[Discuss-gnuradio] GUI python apps don't update controls,

[Chris Stankevitz]

Hi,

Apps with one graph (say "usrp_fft.py -f 103.3") draw a nice plot that 
looks like it's updated at approx 10Hz.  However, the controls (sliders, 
etc) do not respond and do not redraw if I move the window off then back 
onto the page.

Apps with two plots only update one plot at a time at 10Hz for 3 
seconds, then switch to update the other round-robin style.  Ditto for 
three apps.

wfm apps place fine audio.

I'm running SVN revision 4050 on a dual processor 2.4Ghz machine.  The 
CPU is barely used.  Every once in a while python spikes to 30% of one 
of the CPUs, but on average it's near zero.  My machine does not seem 
sluggish.  The hard drive is not active.

My c++ wxWidgets apps behave like this when I use OnIdle to perform 
"infinite loop" processing with a periodic wxSleep() calls.

Anyone know why I get this behavior?

Thanks,

Chris
