Proximity-card reader: no data when app window out of focus
Hello. I can't get it work
My application receives data from em-marin reader only being active. Switching to another app makes the port become silent.
MarinReader works in another thread.
Port reading is going while the app is inactive (tested).
Env: Ubuntu 9.04, Gnome, Qt (i've tryed pure open and fopen - the same result)
Please, help anybody!
Can you not make the reader a separate process - a daemon - that raises a signal or otherwise sends something to your windowing code? An unblocked signal is never ignored, for example.
With the following modification my windowing code gets all the counted signals:
Signals CardProcessed and Message are identical, and the destination slots are in the same thread of main window (I can process these signals with the same slot).
Consider this code snippet below:-
char=`which afplay`
if
then
xterm -e 'while true; do clear; echo "Press Ctrl-C to Quit..."; afplay /tmp/pulse.wav; done' & > /dev/null 2>&1
fi
