Hi,
as I am advancing with TQt slowly, there are many things I want to know, so
I am wondering right now what is the convenient method of reading a device,
so that I can trigger somethin on events emitted by the device. I see there
are few classes based on TQIODevice, but which should I use. I am
interested in following:

I am sure there is a good example somewhere and you know exactly where.
thanks in advance
regards

It turned out to be very easy, indeed and here is the example.
struct rfkill_event event;
event.idx = 0;
event.type = RFKILL_TYPE_BLUETOOTH;
event.op = RFKILL_OP_CHANGE;
if (state == false)
event.soft = 1;
else
event.soft = 0;
TQFile file("/dev/rfkill");
if (!file.open(IO_WriteOnly))
return;
TQDataStream out(&file);
out << event.idx << event.type << event.op << event.soft;
file.close();
this will flip the power switch on the bluetooth device on index idx=0
if I am wrong please let me know
regards
