Graphics / sf::RenderWindow vs sfml/qt

« on: July 23, 2010, 12:22:40 am »

Situation:

I'm using OpenSuse 11.3 with the opensource "radeon" driver for my ATI X1200 (RS690). Performance is worse than it was under 11.2. Funny thing is that qt/SFML app gives me better framerate (within tolerance) than the solo SFML window (way too slow).

Questions

What is the difference in implementation between a sf::RenderWindow and SFML/qt view? Is the former using overlay? If that is the case, it is possible to disable the use of overlay as the "radeon" driver doesn't seem to support them?

Regards,
Frank B.

Is there an easy way to convert qt keycodes to SFML and vice versa?

Audio / Error message with sfml-audip

« on: December 20, 2009, 08:20:17 am »

Hi,

This is error message I'm getting: AL lib: pulseaudio.c:386: Context did not get ready: Connection refused

What does it mean? What's causing it and how to do I fix it?

Code: [Select]



// main.cpp

        int size = file.size();
        char * buf = new char[size];;
        file.read(buf, size);

        char t[5];
        t[4] = 0;
        memcpy(t, buf, 4);
        qDebug("header: %s\n", t);

        CSnd snd;
        snd.Create(buf, size, QString("test"));
        snd.Play();

        delete [] buf;
    }

    return 0;
