Re: [Discuss-gnuradio] No TX on usrp_nbfm_ptt.py example

[Michael Dickens]

Jonathan - For whatever reason, WX on OSX doesn't get SpaceBar events  
correctly, and/or the window of reference in the demo isn't correctly  
focussed.  Either way, the demo just doesn't do what it's supposed to  
on OSX.  Your hardware and other software are most likely OK ... it's  
just the demo with issues.  I'll try to make the change it suggests  
("This REALLY needs to be replaced with a hand-crafted button that  
sends both button down and button up events") ... I have an internal  
version that does this already, and it works quite nicely ... but I  
haven't backported it yet to GR's trunk. - MLD
