Package Summary Overview Summary

### class:Popup [NONE]
-     public class Popup
      extends Object
Popups are used to display a `Component` to the user, typically on top of all the other `Component`s in a particular containment hierarchy. `Popup`s have a very small life cycle. Once you have obtained a `Popup`, and hidden it (invoked the `hide` method), you should no longer invoke any methods on it. This allows the `PopupFactory` to cache `Popup`s for later use. The general contract is that if you need to change the size of the `Component`, or location of the `Popup`, you should obtain a new `Popup`. `Popup` does not descend from `Component`, rather implementations of `Popup` are responsible for creating and maintaining their own `Component`s to render the requested `Component` to the user. You typically do not explicitly create an instance of `Popup`, instead obtain one from a `PopupFactory`. Since: 1.4 See Also: `PopupFactory`

### constructor:Popup(java.awt.Component, java.awt.Component, int, int) [NONE]
- #### Popup
      protected Popup(Component owner,
                      Component contents,
                      int x,
                      int y)
Creates a `Popup` for the Component `owner` containing the Component `contents`. `owner` is used to determine which `Window` the new `Popup` will parent the `Component` the `Popup` creates to. A null `owner` implies there is no valid parent. `x` and `y` specify the preferred initial location to place the `Popup` at. Based on screen size, or other paramaters, the `Popup` may not display at `x` and `y`. Parameters: `owner` - Component mouse coordinates are relative to, may be null `contents` - Contents of the Popup `x` - Initial x screen coordinate `y` - Initial y screen coordinate Throws: `IllegalArgumentException` - if contents is null

### constructor:Popup() [NONE]
- #### Popup
      protected Popup()
Creates a `Popup`. This is provided for subclasses.

### method:show() [NONE]
- #### show
      public void show()
Makes the `Popup` visible. If the `Popup` is currently visible, this has no effect.

### method:hide() [NONE]
- #### 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.
