## Class ShadowPopup

- java.lang.Object
- - javax.swing.Popup
  - - com.jgoodies.looks.common.ShadowPopup

-     public final class ShadowPopup
      extends Popup

  Does all the magic for getting popups with drop shadows. It adds the drop shadow border to the Popup, in `#show` it snapshots the screen background as needed, and in `#hide` it cleans up all changes made before.

- - ### 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 `dispose`d `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`
