Problem from OpenGL to QT OpenGL

[nuts_fever_007]

allrite guys i am sorry for bad description of my problem...but here is what i am saying...

void AntiAliasWidget::run(int value)
{
        //If animation is on (not hit F3 yet), then keep adding height
        // to make effect of sun raising, if over 4.8, then go down to 2.7
        if ((sunDirection == 1) & (animationEnable)) {
                _height += 0.01f;
                if (_height >= 4.8) sunDirection = -1;
        } else if ((sunDirection == -1) & (animationEnable)) {
                _height -= 0.01f;
                if (_height <= 2.7f) sunDirection = 1;
        }
        //glutPostRedisplay();               //Update the display
        updateGL();
        //glutTimerFunc(value, run, 0);      //Call it again in 25 ms
}

void AntiAliasWidget::run(int value)
{
        //If animation is on (not hit F3 yet), then keep adding height
        // to make effect of sun raising, if over 4.8, then go down to 2.7
        if ((sunDirection == 1) & (animationEnable)) {
                _height += 0.01f;
                if (_height >= 4.8) sunDirection = -1;
        } else if ((sunDirection == -1) & (animationEnable)) {
                _height -= 0.01f;
                if (_height <= 2.7f) sunDirection = 1;
        }
        //glutPostRedisplay();               //Update the display
        updateGL();
        //glutTimerFunc(value, run, 0);      //Call it again in 25 ms
}

the source code above have glutTimerFunc function but i dont know how to translate that particular line to QT ... so can someone please tell me how to do it

i hope this will be clear explanation from my part..thank you
