Direct Known Subclasses:

DateField, NumberField, TimeField

public abstract class AbstractBlockField
extends JTextField

The base class for TextFields that supports entering values in blocks. Most notifiably the DateField and the TimeField.
You can use the left/right arrow keys to switch the blocks. Use of the top/down arrow keys will increase/decrease the values in the selected block (page_up/page_down for major changes). You can specify maximum length for each block. If a block reaches this maximum value the focus will switch to the next block.
