Class com.sun.java.swing.DefaultDesktopManager

java.lang.Object
  |
  +--com.sun.java.swing.DefaultDesktopManager

public class DefaultDesktopManager
extends java.lang.Object
implements DesktopManager, java.io.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.

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)
Description copied from interface:
Generally, indicate that this frame has lost focus. This is usually called after the JInternalFrame's IS_SELECTED_PROPERTY has been set to false.
Specified by:
deactivateFrame in interface DesktopManager

beginDraggingFrame

public void beginDraggingFrame(JComponent f)
Description copied from interface:
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.
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)
Description copied from interface:
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.
Specified by:
endDraggingFrame in interface DesktopManager

beginResizingFrame

public void beginResizingFrame(JComponent f,
                               int direction)
Description copied from interface:
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.
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)
Description copied from interface:
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.
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

protected java.awt.Rectangle getBoundsForIconOf(JInternalFrame f)
The iconifyFrame() code calls this to determine the proper bounds for the desktopIcon.

setPreviousBounds

protected void setPreviousBounds(JInternalFrame f,
                                 java.awt.Rectangle r)
Stores the bounds of the component just before a maximize call.

getPreviousBounds

protected java.awt.Rectangle getPreviousBounds(JInternalFrame f)

setWasIcon

protected void setWasIcon(JInternalFrame f,
                          java.lang.Boolean value)
Sets that the component has been iconized and the bounds of the desktopIcon are valid.

wasIcon

protected boolean wasIcon(JInternalFrame f)
