- - ### Constructor Detail

    - #### WindowManager

          public WindowManager(javax.swing.JDesktopPane d,
                               javax.swing.JMenu windowsMenu)

      Constructor. Creates a new `WindowManager` and attaches it to a desktop pane.

      Parameters:
        `d` - The `JDesktopPane` instance.
        `windowsMenu` - The `JMenu` instance.

  - ### Method Detail

    - #### setOutlineDragMode

          public void setOutlineDragMode(boolean outline)

      Selects frames' drawing strategy.

      Parameters:
        `outline` - `true` to enable `JDesktopPane.OUTLINE_DRAG_MODE`, or `false` to enable `JDesktopPane.LIVE_DRAG_MODE`.

    - #### getOutlineDragMode

          public boolean getOutlineDragMode()

      Gets frames' drawing strategy.

      Returns:
        `true` if desktop's `DragMode` is `JDesktopPane.OUTLINE_DRAG_MODE` or `false` if desktop's `DragMode` is `JDesktopPane.LIVE_DRAG_MODE`.

    - #### setDeiconifiablePolicy

          public void setDeiconifiablePolicy(boolean p)

      Sets de-iconifiable policy. Should we force a frame to de-iconify if it is iconified, during cascade operations?

      Parameters:
        `p` - `true` if force, `false` otherwise.

    - #### getDeiconifiablePolicy

          public boolean getDeiconifiablePolicy()

      Gets the de-iconifiable policy.

      Returns:
        The de-iconifiable policy.

    - #### setClosePolicy

          public void setClosePolicy(boolean p)

      Sets the close policy. Should we do default close operation per frame or force close it?

      Parameters:
        `p` - `true` to force close, `false` do default close operation.

    - #### getClosePolicy

          public boolean getClosePolicy()

      Gets the close policy.

      Returns:
        `true` for force close, `false` for default close operation.

    - #### setAutoPositionPolicy

          public void setAutoPositionPolicy(boolean p)

      Sets the auto position frames policy. Should we auto position the new frames in the desktop or not?

      Parameters:
        `p` - `true` for auto-position, `false` for none.

    - #### getAutoPositionPolicy

          public boolean getAutoPositionPolicy()

      Gets the auto position frames policy.

      Returns:
        The auto-position policy.

    - #### countFrames

          public int countFrames()

      Counts all frames, even those that are closed with `DefaultCloseOperation = HIDE_ON_CLOSE`

      NOTEUse this method in order to understand how many "ghost" frames remain within the desktop.

      Returns:
        The number of frames.

    - #### countVisibleFrames

          public int countVisibleFrames()

      Counts only visible frames.

      Returns:
        The number of visible frames.

    - #### close

          public void close()

      Closes the selected frame if it is closable.

    - #### closeAll

          public void closeAll()

      Closes all frames that are closable.

    - #### minimize

          public void minimize()

      Minimizes the selected frame if it is iconifiable.

    - #### minimizeAll

          public void minimizeAll()

      Minimizes all frames that are iconifiable.

    - #### restore

          public void restore()

      Restores the selected frame from it's maximized state.

    - #### restoreAll

          public void restoreAll()

      Restores all frames from their maximized state.

    - #### maximize

          public void maximize()

      Maximizes the selected frame if it is not already maximized.

    - #### maximizeAll

          public void maximizeAll()

      Maximizes all frames that are not already maximized.

    - #### reset

          public void reset()

      Resets the frame to it's original preferred size of its components.

    - #### resetAll

          public void resetAll()

      Resets all frames to their original preferred size of their components.

    - #### hide

          public void hide()

      Hides a frame. The hidden frame is added to the menu with disabled-like color.

    - #### hideAll

          public void hideAll()

      Hides all frames. The hidden frames are added to the menu with disabled-like color.
