ProgressBar not working

[Daepilin]

Hio :)

i wrote my little program where i want to display a calculated BMI using a progress bar.

The progress bar shows its outline, but no value.

my code:

@ bmi_value = new QProgressBar(this);
bmi_value->setValue(250);
bmi_value->setGeometry(25, 120, 350, 40);
bmi_value->setMinimum(0);
bmi_value->setMaximum(1000);@

and:

@void BMI::calc(){
double bmi_tmp(0);

bmi_tmp = weigth_value / (heigth_value * heigth_value);
bmi_value->setValue(bmi_tmp*10);
bmi_value->setFormat("%p");

update();

}@

Do you actually call calc somewhere?
