Your question is not clear to me some how.

if you want slider position, use

Quote:

---

QSlider::value()

and you have a current change value with the help of onValueChanged(int value) // value is the current slider value


If you want current slider value in some other place, have a public function in mainwindow which return

Quote:

---

slider->value()

---

;
And call this where ever you want main/some other class where you have this mainwindow handle.


i don't know what your doing with this code

Code:

---

void MainWindow::onValueChanged(int value)
 
{
 
    int pos = slider->sliderPosition();
    value=pos;    //what are doing here, why are you overwriting value 
//.................
}
