How to use non ui signals/slots?

haxxe

Hi,
i just wanted to try the frameReceived() signal from qcanbus.
But how to do it?
I tried it this way:

connect(can,SIGNAL(framesReceived()),this,SLOT(receiveFrames()));

can is my QCanBus device.
But the programm keeps crashing at the start.
i want to receive some frames, then jump to my receiveFrames function to read it.
Is this a possibility to avoid threads? im not good with threads either (qt noobie, but lover :) )
thanks in advance

Hi
it seems right.

can is a pointer to QCanBusDevice that you have new'ed, correct ?

Could you use the debugger and find the line it crashes on ?

My bad, i new it when i click a button, therefore there is no can before the program starts. after putting the initpart before,it works.
Thanks !
