I want to separate the part of a serial port to read data into a new thread of run , but I Qserialport object pointer is in the main thread, I now want to use the connect preach to participate in the past, but the run not slot function, how to implement the==

Serial port operation involves interaction, so can't completely on the child thread, because the child thread has been while accounted for,

A newcomer just learning QT half a month, meng thread here

CodePudding user response:

Can use global variables, a serial port for data, can be directly used in the thread
