sf::Thread no apropriate default constructor

[n00bish]

I built SFML 2.0 this evening and was reading documentation - I'm having issues with sf::Thread giving me errors when using example code found in http://www.sfml-dev.org/tutorials/1.6/system-threads.php

I'm doing the example with a class inheriting from sf::Thread (pretty much the exact code you see there) - and I get a "'MyThread' : no appropriate default constructor available" error.  Is there a way to resolve it?

Source is below:

Code: [Select]

#include <SFML/System.hpp>
#include <iostream>

sf::Mutex GlobalMutex; // This mutex will be used to synchronize our threads

class MyThread : public sf::Thread {
private :

    virtual void Run() {
        // Lock the mutex, to make sure no thread will interrupt us while we are displaying text
        GlobalMutex.Lock();

        // Print something...
        for (int i = 0; i < 10; ++i)
            std::cout << "I'm the thread number 2" << std::endl;

        // Unlock the mutex
        GlobalMutex.Unlock();
    }
};

int main() {
    // Create an instance of our custom thread class
    MyThread Thread;

    // Start it !
    Thread.Launch();

    // Lock the mutex, to make sure no thread will interrupt us while we are displaying text
    GlobalMutex.Lock();

    // Print something...
    for (int i = 0; i < 10; ++i)
        std::cout << "I'm the main thread" << std::endl;

    // Unlock the mutex
    GlobalMutex.Unlock();

    return EXIT_SUCCESS;
}

I built SFML 2.0 [...] using example code found in http://www.sfml-dev.org/tutorials/1.6/system-threads.php

Well, you can't read the 1.6 documentation/tutorials and use 2.0. A lot of things have changed, you should rather refer to the 2.0 documentation:
http://www.sfml-dev.org/documentation/2.0/

Tutorials haven't been updated yet, but the documentation should be enough.

Sorry - you're right.  I should have mentioned I also took a look at the documentation here: http://www.sfml-dev.org/documentation/2.0/classsf_1_1Thread.htm

The Usage Example for creating a derived class using sf::Thread also uses the same setup, unless I am mistaken.  That's where my confusion lies - since the 1.6 and 2.0 doc seems to match up, and the error still happens even when copying the code from the 2.0 docs.

Thanks for your help.

Oops, I forgot to update the doc :lol:

So you should rather refer to the header (the doc is built from the comments in the header).

Code: [Select]

class MyTask
{
public:

    void Run()
    {
         ...
    }
};

int main()
{
    MyTask task;

    sf::Thread Thread(&MyTask::Run, &task);
    Thread.Launch();

    ...

    return EXIT_SUCCESS;
}

I've updated the doc.

Thank you very much!
