"Blocking" a QThread until a signal has arrived

[tuli]

I have a QThread running, which receives signals from a QProcess (asynchronously). Now I want to "block" a function executing in the context of that thread, until the same thread has received a certain signal from the process.


I would imagine it something like this:

class A
{
bool ready = false;
public:
 
	void get_something()
	{
		while(!ready)
			QThread::currentThread()->[B]get_event_loop()[/B]->processEvents();
 
		//tadaa! now we have what we were waiting for!
		//...
		return xyz;
	}
 
public slots:
	//this slot is connected to the stdout output of a QProcess
	void set_something(...)
	{
		ready = true;
		//...
	}
 
};

class A
{
bool ready = false;
public:

	void get_something()
	{
		while(!ready)
			QThread::currentThread()->[B]get_event_loop()[/B]->processEvents();
		
		//tadaa! now we have what we were waiting for!
		//...
		return xyz;
	}

public slots:
	//this slot is connected to the stdout output of a QProcess
	void set_something(...)
	{
		ready = true;
		//...
	}

};

To copy to clipboard, switch view to plain text mode 

(Note that both get_something() and set_something() live in the same thread)

Problem is that QThread does not have a method to access its QEventLoop!

Any ideas?




----------

As an aside: Currently the GUI thread is the only thread involved (imagine get_something() being something like a buttonpress-event). So I could do QApplicatoin:rocessAllEvents(). But this got me wondering, what if it is not the GUI thread, but any generic QThread? How to access its event loop?
