Constructor Detail

ShadowPopup

public ShadowPopup()

Method Detail

canSnapshot

public static boolean canSnapshot()

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 javax.swing.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 javax.swing.Popup
