  +--com.sun.java.swing.DefaultDesktopManager

public class DefaultDesktopManager

extends Object

implements DesktopManager, Serializable

This is an implementaion of the DesktopManager. It currently implements a the basic behaviors for managing JInternanFrames in an arbitrary parent. JInternalFrames that are not children of a JDesktop will use this component to handle their desktop-like actions.

JDesktopPane, JInternalFrame, Serialized Form

Method Summary

void	activateFrame(JInternalFrame f) Finds all the other peers of type JInternalFrames and set's their IS_SELECTED_PROPERTY to false.
void	beginDraggingFrame(JComponent f)
void	beginResizingFrame(JComponent f, int direction)
void	closeFrame(JInternalFrame f) Removes the frame, and if necessary the desktopIcon, from it's parent.
void	deactivateFrame(JInternalFrame f)
void	deiconifyFrame(JInternalFrame f) Removes the desktopIcon from it's parent and adds it's frame to the parent.
void	dragFrame(JComponent f, int newX, int newY) Calls setBoundsForFrame() with the new values.
void	endDraggingFrame(JComponent f)
void	endResizingFrame(JComponent f)
protected Rectangle	getBoundsForIconOf(JInternalFrame f) The iconifyFrame() code calls this to determine the proper bounds for the desktopIcon.
protected Rectangle	getPreviousBounds(JInternalFrame f)
void	iconifyFrame(JInternalFrame f) Removes the frame from it's parent and adds it's desktopIcon to the parent.
void	maximizeFrame(JInternalFrame f) Resizes the frame to fill it's parents bounds.
void	minimizeFrame(JInternalFrame f) Restores the frame back to it's size and position prior to a maximizeFrame() call.
void	openFrame(JInternalFrame f) Normally this method will not be called.
protected void	removeIconFor(JInternalFrame f) Convience method to remove the desktopIcon of f is necessary.
void	resizeFrame(JComponent f, int newX, int newY, int newWidth, int newHeight) Calls setBoundsForFrame() with the new values.
void	setBoundsForFrame(JComponent f, int newX, int newY, int newWidth, int newHeight) This moves the JComponent and repaints the damaged areas.
protected void	setPreviousBounds(JInternalFrame f, Rectangle r) Stores the bounds of the component just before a maximize call.
protected void	setWasIcon(JInternalFrame f, Boolean value) Sets that the component has been iconized and the bounds of the desktopIcon are valid.
protected boolean	wasIcon(JInternalFrame f)

Method Detail

openFrame

public void openFrame(JInternalFrame f)

Normally this method will not be called. If it is, it try to determine the appropriate parent from the desktopIcon of the frame. Will remove the desktopIcon from it's parent if it successfully adds the frame.

Specified by:

openFrame in interface DesktopManager

closeFrame

public void closeFrame(JInternalFrame f)

Removes the frame, and if necessary the desktopIcon, from it's parent.

Specified by:

closeFrame in interface DesktopManager

maximizeFrame

public void maximizeFrame(JInternalFrame f)

Resizes the frame to fill it's parents bounds.

Specified by:

maximizeFrame in interface DesktopManager

minimizeFrame

public void minimizeFrame(JInternalFrame f)

Restores the frame back to it's size and position prior to a maximizeFrame() call.

Specified by:

minimizeFrame in interface DesktopManager

iconifyFrame

public void iconifyFrame(JInternalFrame f)

Removes the frame from it's parent and adds it's desktopIcon to the parent.

Specified by:

iconifyFrame in interface DesktopManager

deiconifyFrame

public void deiconifyFrame(JInternalFrame f)

Removes the desktopIcon from it's parent and adds it's frame to the parent.

Specified by:

deiconifyFrame in interface DesktopManager

activateFrame

public void activateFrame(JInternalFrame f)

Finds all the other peers of type JInternalFrames and set's their IS_SELECTED_PROPERTY to false. Also moves f to the front.

Specified by:

activateFrame in interface DesktopManager

deactivateFrame

public void deactivateFrame(JInternalFrame f)

Specified by:

deactivateFrame in interface DesktopManager

beginDraggingFrame

public void beginDraggingFrame(JComponent f)

Specified by:

beginDraggingFrame in interface DesktopManager

dragFrame

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

Calls setBoundsForFrame() with the new values.

Specified by:

dragFrame in interface DesktopManager

endDraggingFrame

public void endDraggingFrame(JComponent f)

Specified by:

endDraggingFrame in interface DesktopManager

beginResizingFrame

public void beginResizingFrame(JComponent f,
                               int direction)

Specified by:

beginResizingFrame in interface DesktopManager

resizeFrame

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

Calls setBoundsForFrame() with the new values.

Specified by:

resizeFrame in interface DesktopManager

endResizingFrame

public void endResizingFrame(JComponent f)

Specified by:

endResizingFrame in interface DesktopManager

setBoundsForFrame

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

This moves the JComponent and repaints the damaged areas.

Specified by:

setBoundsForFrame in interface DesktopManager

removeIconFor

protected void removeIconFor(JInternalFrame f)

Convience method to remove the desktopIcon of f is necessary.

getBoundsForIconOf
