public class Thermometer
extends Component

The class Thermometer implements a classical thermometer as graphical Vole component. The final size of the thermometer depends on the width-to-height ratio given by the constructor or the setBounds-method. The thermometer is drawn that it completely fits into its bounding box. A thermometer without any caption has a width-to-height ratio of 2 to 7 plus text height. Any caption will be drawn on the right side of the fluid column, and with a caption, the width-to-height ratio will change. So, if the thermometer is too small or not visible at all, you should try to increase the width first.
