Runtime error on connect
-
I've been trying to connect a signal to a slot and it compiles but once the connect function is run the program the thread gets stuck processing connect for maybe one second before crashing. I must be calling the connect error incorrectly but I can't figure out how. I've included the relevant sections of code below.
@
//It runs until the connect function but never reaches the debug code.
void MainWindow::importThreads(TimerThread* t, AiThread* a){
worker = t->getThread();
aiThread = a;
connect(worker,SIGNAL(timeout()),this,SLOT(refreshPosition()));
qDebug() << "Connected!";
}//This is the slot. This code is never run.
void MainWindow::refreshPosition(){
ui->xPositionDisplay->display(getXPosition());
ui->yPositionDisplay->display(getYPosition());
ui->headingAngleDisplay->display(getHeading());
}
//Declaration of Signal in Worker class
signals:
void timeout();//Declaration of slot in the MainWindow class
public slots:
void refreshPosition();

You don't run MainWindow in a thread other than main, right?
What is value of worker? Can it be nullptr?

You were right about the worker object being a invalid. It turns out the worker pointer in timer thread had yet to be initialized. Thanks.
