public ShadowPopup()

Method Details

getInstance

public static Popup getInstance(Component owner,
 Component contents,
 int x,
 int y,
 Popup delegate)

Returns a previously used ShadowPopup, or a new one if none of the popups have been recycled.

hide

public void hide()

Hides and disposes of the Popup. Once a Popup has been disposed you should no longer invoke methods on it. A disposed Popup may be reclaimed and later used based on the PopupFactory. As such, if you invoke methods on a disposed Popup, indeterminate behavior will result.

In addition to the superclass behavior, we reset the stored horizontal and vertical drop shadows - if any.

Overrides:

hide in class Popup

show

public void show()

Makes the Popup visible. If the popup has a heavy-weight container, we try to snapshot the background. If the Popup is currently visible, it remains visible.

Overrides:

show in class Popup
