    unit="s",
    val=1.0,
    val_min=0.0,
    val_max=10.0,
    val_fmt="{:.3g}",
)
slider.valueChanged.connect(lambda v: print(f"Value: {v}"))

IntSlider

from pyside6_sliders import IntSlider

slider = IntSlider(
    name="N",
    unit="",
    val=10,
    val_min=1,
    val_max=100,
)

FloatRangeSlider

from pyside6_sliders import FloatRangeSlider

slider = FloatRangeSlider(
    name=r"\nu",
    unit="MHz",
    val=(1.0, 5.0),

    val_max=10.0,
)
slider.valueChanged.connect(lambda v: print(f"Range: {v}"))

    val=np.array([1.0, 2.0, 3.0]),
    val_min=0.0,
    val_max=10.0,
)
