Direct Known Subclasses:

ProductExpressionPane

public class ExpressionPane
extends JPanel

The expression pane is a UI component which is used to edit mathematical expressions. There are four methods which can be used to customize the UI of the expression pane: {@link #setLeftAccessory}, {@link #setRightAccessory}, {@link #setTopAccessory} and {@link #setBottomAccessory}.
