Interface DesktopManager

All Known Implementing Classes:
  DefaultDesktopManager

    public interface DesktopManager

DesktopManager objects are owned by a JDesktopPane object. They are responsible for implementing L&F specific behaviors for the JDesktopPane. JInternalFrame implementations should delegate specific behaviors to the DesktopManager. For instance, if a JInternalFrame was asked to iconify, it should try:

        getDesktopPane().getDesktopManager().iconifyFrame(frame);

This delegation allows each L&F to provide custom behaviors for desktop-specific actions. (For example, how and where the internal frame's icon would appear.)

This class provides a policy for the various JInternalFrame methods, it is not meant to be called directly rather the various JInternalFrame methods will call into the DesktopManager.

  `JDesktopPane`, `JInternalFrame`, `JInternalFrame.JDesktopIcon`

Method Summary
`void` | `activateFrame(JInternalFrame f)` Generally, indicate that this frame has focus.
`void` | `beginDraggingFrame(JComponent f)` This method is normally called when the user has indicated that they will begin dragging a component around.
`void` | `beginResizingFrame(JComponent f, int direction)` This methods is normally called when the user has indicated that they will begin resizing the frame.
`void` | `closeFrame(JInternalFrame f)` Generally, this call should remove the frame from it's parent.
`void` | `deactivateFrame(JInternalFrame f)` Generally, indicate that this frame has lost focus.
`void` | `deiconifyFrame(JInternalFrame f)` Generally, remove any iconic representation that is present and restore the frame to it's original size and location.
`void` | `dragFrame(JComponent f, int newX, int newY)` The user has moved the frame.
`void` | `endDraggingFrame(JComponent f)` This method signals the end of the dragging session.
`void` | `endResizingFrame(JComponent f)` This method signals the end of the resize session.
`void` | `iconifyFrame(JInternalFrame f)` Generally, remove this frame from it's parent and add an iconic representation.
`void` | `maximizeFrame(JInternalFrame f)` Generally, the frame should be resized to match it's parents bounds.
`void` | `minimizeFrame(JInternalFrame f)` Generally, this indicates that the frame should be restored to it's size and position prior to a maximizeFrame() call.
`void` | `openFrame(JInternalFrame f)` If possible, display this frame in an appropriate location.
`void` | `resizeFrame(JComponent f, int newX, int newY, int newWidth, int newHeight)` The user has resized the component.
`void` | `setBoundsForFrame(JComponent f, int newX, int newY, int newWidth, int newHeight)` This is a primitive reshape method.

Method Detail

### openFrame

    void openFrame(JInternalFrame f)

  If possible, display this frame in an appropriate location. Normally, this is not called, as the creator of the JInternalFrame will add the frame to the appropriate parent.

### closeFrame

    void closeFrame(JInternalFrame f)

  Generally, this call should remove the frame from it's parent.

### maximizeFrame

    void maximizeFrame(JInternalFrame f)

  Generally, the frame should be resized to match it's parents bounds.

### minimizeFrame

    void minimizeFrame(JInternalFrame f)

  Generally, this indicates that the frame should be restored to it's size and position prior to a maximizeFrame() call.

### iconifyFrame

    void iconifyFrame(JInternalFrame f)

  Generally, remove this frame from it's parent and add an iconic representation.

### deiconifyFrame

    void deiconifyFrame(JInternalFrame f)

  Generally, remove any iconic representation that is present and restore the frame to it's original size and location.

### activateFrame

    void activateFrame(JInternalFrame f)

  Generally, indicate that this frame has focus. This is usually called after the JInternalFrame's IS_SELECTED_PROPERTY has been set to true.

### deactivateFrame

    void deactivateFrame(JInternalFrame f)

  Generally, indicate that this frame has lost focus. This is usually called after the JInternalFrame's IS_SELECTED_PROPERTY has been set to false.

### beginDraggingFrame

    void beginDraggingFrame(JComponent f)

  This method is normally called when the user has indicated that they will begin dragging a component around. This method should be called prior to any dragFrame() calls to allow the DesktopManager to prepare any necessary state. Normally f will be a JInternalFrame.

### dragFrame

    void dragFrame(JComponent f,
                   int newX,
                   int newY)

  The user has moved the frame. Calls to this method will be preceded by calls to beginDraggingFrame(). Normally f will be a JInternalFrame.

### endDraggingFrame

    void endDraggingFrame(JComponent f)

  This method signals the end of the dragging session. Any state maintained by the DesktopManager can be removed here. Normally f will be a JInternalFrame.

### beginResizingFrame

    void beginResizingFrame(JComponent f,
                            int direction)

  This methods is normally called when the user has indicated that they will begin resizing the frame. This method should be called prior to any resizeFrame() calls to allow the DesktopManager to prepare any necessary state. Normally f will be a JInternalFrame.

### resizeFrame

    void resizeFrame(JComponent f,
                     int newX,
                     int newY,
                     int newWidth,
                     int newHeight)

  The user has resized the component. Calls to this method will be preceded by calls to beginResizingFrame(). Normally f will be a JInternalFrame.

### endResizingFrame

    void endResizingFrame(JComponent f)

  This method signals the end of the resize session. Any state maintained by the DesktopManager can be removed here. Normally f will be a JInternalFrame.

### setBoundsForFrame

    void setBoundsForFrame(JComponent f,
                           int newX,
                           int newY,
                           int newWidth,
                           int newHeight)

  This is a primitive reshape method.
