Answer 1

You need to set the minimum and maximum values with:

void    setMaximum ( int )
void    setMinimum ( int )

Optionally set the initial value with void setValue ( int )

Answer 2

If you wanted to do it all in the constructor:

QSlider::QSlider( int minValue, int maxValue, int pageStep, int value, Orientation orientation, QWidget * parent, const char * name = 0 )

like this:

Slider= new QSlider( 0, 100, 1, 0, Qt::Horizontal, this);

Assuming you are using a percentage of 0<->100,
