DesktopManager JDK 1.6)

Description

public interface DesktopManager

DesktopManager objects are owned by a JDesktopPane object.

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.

Methods

Hide/Show inherited methods

public void activateFrame (JInternalFrame f)

Generally, indicate that this frame has focus.

public void beginDraggingFrame (JComponent f)

This method is normally called when the user has indicated that they will begin dragging a component around.

public void beginResizingFrame (JComponent f, int direction)

This methods is normally called when the user has indicated that they will begin resizing the frame.

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.

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.

public void endDraggingFrame (JComponent f)

This method signals the end of the dragging session.

public void endResizingFrame (JComponent f)

This method signals the end of the resize session.

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.

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

The user has resized the component.

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

This is a primitive reshape method.
