Hello,
I have to face a problem with alarm sensor. I have a qLineEdit where values are modified by an external widget (it manages data from a serial port).
Now I need that, when values exceed a defined level, an action is trigged (just like an alarm, or a motor power on, etc.).
I tried to use a signal/slot for the qLineEdit (_textChanged event with a simple "if ()" condition), it's ok for slow data flow, but obviously, for an high data rate ( as from a fast voltage sensor, a position device, a piece counter), it's freeze my code. So I'm searching a better strategy, did you have any suggestion? Thanks!!
