PopupMenuUI
public PopupMenuUI()
Constructs a new PopupMenuUI.
getPopup
public Popup getPopup(JPopupMenu popup,
int x,
int y) Creates a
Popup for displaying the popup menu. The
default implementation uses the
PopupFactory
for retrieving a suitable
Popup, but subclasses
might want to override this method if a LookAndFeel needs special
Popups.
popup - the JPopupMenu for whose display
a Popup is needed.x - the horizontal position where the popup will be
displayed.y - the vertical position where the popup will be
displayed.
- a
Popup for showing and hiding
the menu.
isPopupTrigger
public boolean isPopupTrigger(MouseEvent event)
Tests whether or not a mouse event triggers a popup menu.
The default implementation calls
event.isPopupTrigger(), which checks for the gesture
that is common for the platform on which the application runs. If
a look and feel wants to employ non-standard conventions for
triggering a popup menu, it can override this method.
event - the event to check.
true if the event triggers a popup menu;
false otherwise.
