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:
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.
| Method from javax.swing.DesktopManager Detail: |
public 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. |
public 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. |
public 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. |
public void closeFrame(JInternalFrame f)
Generally, this call should remove the frame from it's parent. |
public 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. |
public void deiconifyFrame(JInternalFrame f)
Generally, remove any iconic representation that is present and restore the
frame to it's original size and location. |
public 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. |
public 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. |
public 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. |
public void iconifyFrame(JInternalFrame f)
Generally, remove this frame from it's parent and add an iconic representation. |
public void maximizeFrame(JInternalFrame f)
Generally, the frame should be resized to match it's parents bounds. |
public void minimizeFrame(JInternalFrame f)
Generally, this indicates that the frame should be restored to it's
size and position prior to a maximizeFrame() call. |
public 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. |
public 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. |
public void setBoundsForFrame(JComponent f,
int newX,
int newY,
int newWidth,
int newHeight)
This is a primitive reshape method. |
