Package Summary  Overview Summary

class:DefaultDesktopManager [NONE]
All Implemented Interfaces:
Serializable, DesktopManager 
public class DefaultDesktopManager
extends Object
implements DesktopManager, Serializable
This is an implementation of the DesktopManager. It currently implements the basic behaviors for managing JInternalFrames in an arbitrary parent. JInternalFrames that are not children of a JDesktop will use this component to handle their desktop-like actions.

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.

Since:
1.2

constructor:DefaultDesktopManager() [NONE]

method:openFrame(javax.swing.JInternalFrame) [NONE]

  • openFrame

    public void openFrame?(JInternalFrame f)

    public void closeFrame?(JInternalFrame f)
    Removes the frame, and, if necessary, the desktopIcon, from its parent.
    Specified by:
    closeFrame in interface DesktopManager
    Parameters:
    f - the JInternalFrame to be removed

    method:maximizeFrame(javax.swing.JInternalFrame) [NONE]

    method:activateFrame(javax.swing.JInternalFrame) [NONE]

    activateFrame

    public void activateFrame?(JInternalFrame f)
    This will activate f moving it to the front. It will set the current active frame's (if any) IS_SELECTED_PROPERTY to false. There can be only one active frame across all Layers.

    f - the JInternalFrame to be deactivated

    method:beginDraggingFrame(javax.swing.JComponent) [NONE]

    beginDraggingFrame

    public void beginDraggingFrame?(JComponent f)
    Description copied from interface: DesktopManager
    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.

    dragFrame

    public void dragFrame?(JComponent f, int newX, int newY)
    Moves the visible location of the frame being dragged to the location specified. The means by which this occurs can vary depending on the dragging algorithm being used. The actual logical location of the frame might not change until endDraggingFrame is called.
    Specified by:
    dragFrame in interface DesktopManager
