Interface DesktopManager

public interface DesktopManager

DesktopManagers are responsible for implementing the behaviours for the JInternalFrames that belong to JDesktopPanes. Actions such as maximizing, minimizing, iconifying, etc will be delegated to the DesktopManager.

Method Summary
void	activateFrame(JInternalFrame vframe) This method should give focus to the JInternalFrame and its default focus owner.
void	beginDraggingFrame(JComponent frame) This method should be called in preparation for dragging.
void	beginResizingFrame(JComponent frame, int direction) This method should be called prior to any resizeFrame calls.
void	closeFrame(JInternalFrame frame) This method should remove the JInternalFrame from its parent.
void	deactivateFrame(JInternalFrame frame) This method should be called when the JInternalFrame gets deselected and subsequently loses focus.
void	deiconifyFrame(JInternalFrame frame) This method should remove the JDesktopIcon from its parent and replace it with the JInternalFrame that the JDesktopIcon represents.
void	dragFrame(JComponent frame, int x, int y) This method drags the given JInternalFrame to the given x and y coordinates.
void	endDraggingFrame(JComponent frame) This method should be called after dragFrame calls.
void	endResizingFrame(JComponent frame) This method is called to signify that the resize is finished.
void	iconifyFrame(JInternalFrame frame) This method should remove the JInternalFrame from its parent and replace it with a JDesktopIcon.
void	maximizeFrame(JInternalFrame frame) This method should maximize the JInternalFrame to match its parent's bounds.
void	minimizeFrame(JInternalFrame frame) This method should restore the JInternalFrame to its normal bounds.
void	openFrame(JInternalFrame frame) This method will cause the JInternalFrame to be displayed in the set location.
void	resizeFrame(JComponent frame, int x, int y, int width, int height) This method is called to resize the given JInternalFrame to the given bounds.
void	setBoundsForFrame(JComponent frame, int x, int y, int width, int height) This method does the actual work for reshaping the JInternalFrame.

Method Detail

activateFrame

public void activateFrame(JInternalFrame vframe)

This method should give focus to the JInternalFrame and its default focus owner.

Parameters: vframe The JInternalFrame to activate.

beginDraggingFrame

public void beginDraggingFrame(JComponent frame)

This method should be called in preparation for dragging. This needs to be called prior to dragFrame calls so that the DesktopManager can prepare any state information.

Parameters: frame The JInternalFrame to prepare for dragging.

beginResizingFrame

public void beginResizingFrame(JComponent frame, int direction)

This method should be called prior to any resizeFrame calls. Any state information needed by the DesktopManager to resize the JInternalFrame will be prepared here.

Parameters: frame The JInternalFrame to resize. direction One of eight directions specified by SwingConstants.

closeFrame

public void closeFrame(JInternalFrame frame)

This method should remove the JInternalFrame from its parent.

Parameters: frame The JInternalFrame to close.

deactivateFrame

public void deactivateFrame(JInternalFrame frame)

This method should be called when the JInternalFrame gets deselected and subsequently loses focus.

Parameters: frame The JInternalFrame to deactivate.

deiconifyFrame

public void deiconifyFrame(JInternalFrame frame)

This method should remove the JDesktopIcon from its parent and replace it with the JInternalFrame that the JDesktopIcon represents.

Parameters: frame The JInternalFrame to deiconify.

dragFrame

public void dragFrame(JComponent frame, int x, int y)

This method drags the given JInternalFrame to the given x and y coordinates.

Parameters: frame The JInternalFrame to drag. x The new x coordinate. y The new y coordinate.

endDraggingFrame

public void endDraggingFrame(JComponent frame)

This method should be called after dragFrame calls. Any information used by the DesktopManager for dragging the JInternalFrame can be cleared.

Parameters: frame The JInternalFrame that finished dragging.

endResizingFrame

public void endResizingFrame(JComponent frame)

This method is called to signify that the resize is finished. Any information used to resize the JInternalFrame can now be cleared.

Parameters: frame The JInternalFrame that just finished dragging.

iconifyFrame

public void iconifyFrame(JInternalFrame frame)

This method should remove the JInternalFrame from its parent and replace it with a JDesktopIcon.

Parameters: frame The JInternalFrame to iconify.

maximizeFrame

public void maximizeFrame(JInternalFrame frame)

This method should maximize the JInternalFrame to match its parent's bounds.

Parameters: frame The JInternalFrame to maximize.

minimizeFrame

public void minimizeFrame(JInternalFrame frame)

This method should restore the JInternalFrame to its normal bounds.

Parameters: frame The JInternalFrame to minimize.

openFrame

public void openFrame(JInternalFrame frame)

This method will cause the JInternalFrame to be displayed in the set location. This usually is not needed since the user will add the JInternalFrame to a Container separately.

Parameters: frame The JInternalFrame to open.

resizeFrame

public void resizeFrame(JComponent frame, int x, int y, int width, int height)

This method is called to resize the given JInternalFrame to the given bounds.

Parameters: frame The JInternalFrame to resize. x The new x coordinate. y The new y coordinate. width The new width. height The new height.

setBoundsForFrame

public void setBoundsForFrame(JComponent frame, int x, int y, int width, int height)

This method does the actual work for reshaping the JInternalFrame.

Parameters: frame The JInternalFrame to resize. x The new x coordinate. y The new y coordinate. width The new width. height The new height.
