Threading...?

[sekatsim]

I'm sorry, I don't quite understand. I have

class joystick1Thread : public QThread
{
	Q_OBJECT
 
	signals:
	void axischanged();
 
	public:
	void prepare();
 
	protected:
	void run();
 
};

class joystick1Thread : public QThread
{
	Q_OBJECT
	
	signals:
	void axischanged();

	public:
	void prepare();
	
	protected:
	void run();

};

In my .h file. Are you saying that I should put my "connect" in the .h file as well?

No, don_simmmel suggested that you should try making your thread a member variable, instead of local one.

Sounds like a typical usage for the Observer pattern

I've been playing with this when I've gotten time during the week, and still no results.

When you say I should make my thread a member variable, do you mean the declaration of the thread, the actual physical thread itself, or the "connect" command? As far as I could tell according to the QT documentation, I have it set up correctly. If you could tell me what section of my code I should put where, I'd love to try it out.

The thread has its own class, which is declared in the mainwindowimpl.h file, I dont know how much more global I can get than that.

None of these things is a variable. "thread" which appears in post #4 is a variable and it's the one don_simmmel had on mind. Where do you declare it?

[sekatsim]

Okay, now I understand. I didnt even consider that, as I'd copied this as close-to-originally as possible from the Mandelbrot example. "thread" was declared in the "private:" of mainwindowimpl. I moved it into "public:", and the program no longer crashes when I enable the joystick.

However, I still get a "QThread: Destroyed while thread is still running" on enable, and the connect still seems to be failing.

Where *should* I be declaring "thread"?

Making it a member variable is a good solution, provided that the object it's member of will exist longer than the thread runs.

When exactly do you get that "Destroyed while thread is still running" message?

Thanks, I got it working. I basically just started over from scratch, using the Mandelbrot example, and then gradually modified it to suit my own purposes.
