  :setSize(1, 10)
  :setMaxValue(20)

  end)

basalt.autoUpdate()

In this example, a Slider object is created and added to the mainFrame. The getPosition, setSize, and setMaxValue methods are used to adjust the position, size, and maximum value of the Slider. A button is added to the mainFrame to change the index of the Slider to 1 when clicked.

<slider index="2" />
