[Touch-packages] [Bug 1508485] Re: "QThread: Destroyed while thread is still running" printed on shutdown

2015-10-21 Thread Gerry Boland

DashCommunicator inherits QThread. From the QThread docs:

"Note that deleting a QThread object will not stop the execution of the
thread it manages. Deleting a running QThread (i.e. isFinished() returns
false) will probably result in a program crash. Wait for the finished()
signal before deleting the QThread."

So to fix this, need to refactor DashCommunicator a bit to only delete
the QThread after the thread's finished() signal has fired.
