How do I get the value from the slider's position?

[anda_skoa]

I tried to connect the slider to the push button using the value changed signal but this only works one time for the first push button.

Instead of that you connect the valueChanged(int) signal to a slot and the do a switch on the value passed to that slot.
For each value the respective case statement will then call the appropriate slot.
