What SWT widget does the SineWave class use to allow user interaction?

  1. Button

  2. Slider

  3. Text

  4. List

The correct answer is: Slider

The SineWave class uses a Slider widget to allow user interaction. Slider allows the user to select from a range of values by dragging a knob along a track. This is different from a Button, which is a simple control that can not support a range of values. Text and List are also incorrect because they are used for input and selection respectively, and do not allow for interactive manipulation of values. In contrast, Slider provides a visually intuitive way for users to interact with the SineWave class.
