Class ButtonStackBuilder

A non-visual builder that assists you in building consistent button stacks using the {@link FormLayout}.

This builder sets a hint for narrow margin for the gridded buttons. This can reduce the button stack's width if some buttons have long texts. For example, a stack with 'OK', 'Cancel', 'Configure...' will likely exceed the minimum button width. The narrow margins help getting narrow stacks. Note that some look&feels do not support the narrow margin feature, and conversely, others have only narrow margins. The JGoodies look&feels honor the setting, the Mac Aqua l&f uses narrow margins all the time.

Example:
The following example builds a button stack with Close, Up and Down, where Up and Down are related, and Close is not related to the other buttons, which makes a wide gap for the unrelated and a smaller gap for the related buttons.

 private JPanel createCloseUpDownButtonStack(
         JButton close, JButton up, JButton down) {
     ButtonStackBuilder builder = new ButtonStackBuilder();
     builder.addGridded(close);
     builder.addUnrelatedGap();
     builder.addGridded(up);
     builder.addRelatedGap();
     builder.addGridded(down);
     return builder.getPanel();
 }
