public class DropDownMenuButton
An implementation of a two-state button that shows a drop-down JPopupMenu
when the button is selected. The menu is shown automatically when the button is selected. The menu is hidden automatically when the button is deselected, and the button is deselected automatically when the menu is hidden.
The button has several convenience methods for manipulating the drop-down menu. The button model must be an instance of DropDownButtonModel
, which owns the menu associated with the button. The menu may be manipulated directly through the model or through the getPopupMenu()
method, if desired.
If the button's drop-down menu is static, then the menu may be pre-populated with the menu choices upon creation.
If the button's drop-down menu is dynamic, then the client will typically add an ItemListener
to listen for changes in the button's selection state. The menu should be populated when the ItemEvent.SELECTED
change event is received, and it should be cleared when the ItemEvent.DESELECTED
change event is received.
The typical usage pattern for a dynamic drop-down menu button is as follows:
import java.awt.ItemEvent; import java.awt.ItemListener; // Create the button. final DropDownMenuButton button = new DropDownMenuButton(); // Add a listener to respond to button state changes and manipulate // the dynamic menu. button.addItemListener(new ItemListener() { public void itemStateChanged(ItemEvent e) { if (e.getStateChange() == ItemEvent.SELECTED) { // Populate the button menu... // For example: // button.addPopupItem(JMenuItem); // button.addPopupItem(Action); // button.addPopupItem(String); // button.addPopupSeparator(); // ... } else if (e.getStateChange() == ItemEvent.DESELECTED) { // Clear the button menu. button.removeAllPopupItems(); } } });
