public class Frame extends Window implements MenuContainer
A `Frame` is a top-level window with a title and a border.

The size of the frame includes any area designated for the border. The dimensions of the border area may be obtained using the `getInsets` method, however, since these dimensions are platform-dependent, a valid insets value cannot be obtained until the frame is made displayable by either calling `pack` or `show`. Since the border area is included in the overall size of the frame, the border effectively obscures a portion of the frame, constraining the area available for rendering and/or displaying subcomponents to the rectangle which has an upper-left corner location of `(insets.left, insets.top)`, and has a size of `width - (insets.left + insets.right)` by `height - (insets.top + insets.bottom)`.

The default layout for a frame is `BorderLayout`.

A frame may have its native decorations (i.e. `Frame` and `Titlebar`) turned off with `setUndecorated`. This can only be done while the frame is not `displayable`.

In a multi-screen environment, you can create a `Frame` on a different screen device by constructing the `Frame` with `Frame(GraphicsConfiguration)` or `Frame(String title, GraphicsConfiguration)`. The `GraphicsConfiguration` object is one of the `GraphicsConfiguration` objects of the target screen device.

In a virtual device multi-screen environment in which the desktop area could span multiple physical screen devices, the bounds of all configurations are relative to the virtual-coordinate system. The origin of the virtual-coordinate system is at the upper left-hand corner of the primary physical screen. Depending on the location of the primary screen in the virtual device, negative coordinates are possible, as shown in the following figure.

In such an environment, when calling `setLocation`, you must pass a virtual coordinate to this method. Similarly, calling `getLocationOnScreen` on a `Frame` returns virtual device coordinates. Call the `getBounds` method of a `GraphicsConfiguration` to find its origin in the virtual coordinate system.

The following code sets the location of the `Frame` at (10, 10) relative to the origin of the physical screen of the corresponding `GraphicsConfiguration`. If the bounds of the `GraphicsConfiguration` is not taken into account, the `Frame` location would be set at (10, 10) relative to the virtual-coordinate system and would appear on the primary physical screen, which might be different from the physical screen of the specified `GraphicsConfiguration`.

         Frame f = new Frame(GraphicsConfiguration gc);
         Rectangle bounds = gc.getBounds();
         f.setLocation(10 + bounds.x, 10 + bounds.y);

Frames are capable of generating the following types of `WindowEvent`s:

- `WINDOW_OPENED`
- `WINDOW_CLOSING`:
  If the program doesn't explicitly hide or dispose the window while processing this event, the window close operation is canceled.
- `WINDOW_CLOSED`
- `WINDOW_ICONIFIED`
- `WINDOW_DEICONIFIED`
- `WINDOW_ACTIVATED`
- `WINDOW_DEACTIVATED`
- `WINDOW_GAINED_FOCUS`
- `WINDOW_LOST_FOCUS`
- `WINDOW_STATE_CHANGED`

  1.0

    Overrides:
      `addNotify` in class `Window`
    See Also:
      - `Component.isDisplayable()`
      - `removeNotify()`

    See Also:
      - `getTitle()`

  - ### getIconImage

    public Image getIconImage()
    Returns the image to be displayed as the icon for this frame.

    This method is obsolete and kept for backward compatibility only. Use `Window.getIconImages()` instead.

    If a list of several images was specified as a Window's icon, this method will return the first item of the list.

    Returns:
      the icon image for this frame, or `null` if this frame doesn't have an icon image.
    See Also:
      - `Window.setIconImage(Image)`
      - `Window.getIconImages()`
      - `Window.setIconImages(List)`

  - ### getMenuBar

    public MenuBar getMenuBar()
    Gets the menu bar for this frame.
    Returns:
      the menu bar for this frame, or `null` if this frame doesn't have a menu bar.
    See Also:
      - `setMenuBar(MenuBar)`

  - ### setMenuBar

    public void setMenuBar(MenuBar mb)
    Sets the menu bar for this frame to the specified menu bar.
    Parameters:
      `mb` - the menu bar being set. If this parameter is `null` then any existing menu bar on this frame is removed.
    See Also:
      - `getMenuBar()`

  - ### isResizable

    public boolean isResizable()
    Indicates whether this frame is resizable by the user. By default, all frames are initially resizable.
    Returns:
      `true` if the user can resize this frame; `false` otherwise.
    See Also:
      - `setResizable(boolean)`

  - ### setResizable

    public void setResizable(boolean resizable)
    Sets whether this frame is resizable by the user.
    Parameters:
      `resizable` - `true` if this frame is resizable; `false` otherwise.
    See Also:
      - `isResizable()`

  - ### setState

    public void setState(int state)
    Sets the state of this frame (obsolete).

    In older versions of JDK a frame state could only be NORMAL or ICONIFIED. Since JDK 1.4 set of supported frame states is expanded and frame state is represented as a bitwise mask.

    For compatibility with applications developed earlier this method still accepts `Frame.NORMAL` and `Frame.ICONIFIED` only. The iconic state of the frame is only changed, other aspects of frame state are not affected by this method. If the state passed to this method is neither `Frame.NORMAL` nor `Frame.ICONIFIED` the method performs no actions at all.

    Note that if the state is not supported on a given platform, neither the state nor the return value of the `getState()` method will be changed. The application may determine whether a specific state is supported via the `Toolkit.isFrameStateSupported(int)` method.

    If the frame is currently visible on the screen (the `Window.isShowing()` method returns `true`), the developer should examine the return value of the `WindowEvent.getNewState()` method of the `WindowEvent` received through the `WindowStateListener` to determine that the state has actually been changed.

    If the frame is not visible on the screen, the events may or may not be generated. In this case the developer may assume that the state changes immediately after this method returns. Later, when the `setVisible(true)` method is invoked, the frame will attempt to apply this state. Receiving any `WindowEvent.WINDOW_STATE_CHANGED` events is not guaranteed in this case also.

    Parameters:
      `state` - either `Frame.NORMAL` or `Frame.ICONIFIED`.
    See Also:
      - `setExtendedState(int)`
      - `Window.addWindowStateListener(WindowStateListener)`

  - ### setExtendedState

    public void setExtendedState(int state)
    Sets the state of this frame. The state is represented as a bitwise mask.
    - `NORMAL`
      Indicates that no state bits are set.
    - `ICONIFIED`
    - `MAXIMIZED_HORIZ`
    - `MAXIMIZED_VERT`
    - `MAXIMIZED_BOTH`
      Concatenates `MAXIMIZED_HORIZ` and `MAXIMIZED_VERT`.

    Note that if the state is not supported on a given platform, neither the state nor the return value of the `getExtendedState()` method will be changed. The application may determine whether a specific state is supported via the `Toolkit.isFrameStateSupported(int)` method.

    If the frame is currently visible on the screen (the `Window.isShowing()` method returns `true`), the developer should examine the return value of the `WindowEvent.getNewState()` method of the `WindowEvent` received through the `WindowStateListener` to determine that the state has actually been changed.

    If the frame is not visible on the screen, the events may or may not be generated. In this case the developer may assume that the state changes immediately after this method returns. Later, when the `setVisible(true)` method is invoked, the frame will attempt to apply this state. Receiving any `WindowEvent.WINDOW_STATE_CHANGED` events is not guaranteed in this case also.

    Parameters:
      `state` - a bitwise mask of frame state constants
    Since:
      1.4
    See Also:
      - `Window.addWindowStateListener(WindowStateListener)`

  - ### getState

    public int getState()
    Gets the state of this frame (obsolete).

    In older versions of JDK a frame state could only be NORMAL or ICONIFIED. Since JDK 1.4 set of supported frame states is expanded and frame state is represented as a bitwise mask.

    For compatibility with old programs this method still returns `Frame.NORMAL` and `Frame.ICONIFIED` but it only reports the iconic state of the frame, other aspects of frame state are not reported by this method.

    Returns:
      `Frame.NORMAL` or `Frame.ICONIFIED`.
    See Also:
      - `setState(int)`
      - `getExtendedState()`

  - ### getExtendedState

    public int getExtendedState()
    Gets the state of this frame. The state is represented as a bitwise mask.
    - `NORMAL`
      Indicates that no state bits are set.
    - `ICONIFIED`
    - `MAXIMIZED_HORIZ`
    - `MAXIMIZED_VERT`
    - `MAXIMIZED_BOTH`
      Concatenates `MAXIMIZED_HORIZ` and `MAXIMIZED_VERT`.
    Returns:
      a bitwise mask of frame state constants
    Since:
      1.4
    See Also:
      - `setExtendedState(int)`

  - ### setMaximizedBounds

    public void setMaximizedBounds(Rectangle bounds)
    Sets the maximized bounds for this frame.

    When a frame is in maximized state the system supplies some defaults bounds. This method allows some or all of those system supplied values to be overridden.

    If `bounds` is `null`, accept bounds supplied by the system. If non-`null` you can override some of the system supplied values while accepting others by setting those fields you want to accept from system to `Integer.MAX_VALUE`.

    Note, the given maximized bounds are used as a hint for the native system, because the underlying platform may not support setting the location and/or size of the maximized windows. If that is the case, the provided values do not affect the appearance of the frame in the maximized state.

    Parameters:
      `bounds` - bounds for the maximized state
    Since:
      1.4
    See Also:
      - `getMaximizedBounds()`

  - ### getMaximizedBounds

    public Rectangle getMaximizedBounds()
    Gets maximized bounds for this frame. Some fields may contain `Integer.MAX_VALUE` to indicate that system supplied values for this field must be used.
    Returns:
      maximized bounds for this frame; may be `null`
    Since:
      1.4
    See Also:
      - `setMaximizedBounds(Rectangle)`

  - ### setUndecorated

    public void setUndecorated(boolean undecorated)
    Disables or enables decorations for this frame.

    This method can only be called while the frame is not displayable. To make this frame decorated, it must be opaque and have the default shape, otherwise the `IllegalComponentStateException` will be thrown. Refer to `Window.setShape(Shape)`, `Window.setOpacity(float)` and `Window.setBackground(Color)` for details

    Parameters:
      `undecorated` - `true` if no frame decorations are to be enabled; `false` if frame decorations are to be enabled
    Throws:
      `IllegalComponentStateException` - if the frame is displayable
      `IllegalComponentStateException` - if `undecorated` is `false`, and this frame does not have the default shape
      `IllegalComponentStateException` - if `undecorated` is `false`, and this frame opacity is less than `1.0f`
      `IllegalComponentStateException` - if `undecorated` is `false`, and the alpha value of this frame background color is less than `1.0f`

    See Also:
      - `Component.add(PopupMenu)`

  - ### removeNotify

    public void removeNotify()
    Makes this Frame undisplayable by removing its connection to its native screen resource. Making a Frame undisplayable will cause any of its children to be made undisplayable. This method is called by the toolkit internally and should not be called directly by programs.

  - ### getFrames

    public static Frame[] getFrames()
    Returns an array of all `Frame`s created by this application.

    Warning: this method may return system created frames, such as a shared, hidden frame which is used by Swing. Applications should not assume the existence of these frames, nor should an application assume anything about these frames such as component positions, `LayoutManager`s or serialization.

    Note: To obtain a list of all ownerless windows, including ownerless `Dialog`s (introduced in release 1.6), use `Window.getOwnerlessWindows`.
