Slider slider = new Slider(1, 5);
slider.setValue(1.0);

If set the value as minium value for the first time, if wont trigger the valueChangedListener for the slider. Are there any ways to trigger it?

I doubt there is a proper way of doing this. However, this workaround might work:

Slider slider = new Slider(1, 5);
slider.setValue(1.000001);

Or otherwise you could just create a method that’s called from the value change listener and call that method once, so you won’t have to resort to tricks.
