java.lang.Objectjavax.swing.DefaultDesktopManager
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.

DefaultDesktopManager()
|
|
| Method Summary | |
void |
activateFrame(JInternalFrame f)
This will activate f moving it to the front. |
void |
beginDraggingFrame(JComponent f)
This method is normally called when the user has indicated that they will begin dragging a component around. |
void |
beginResizingFrame(JComponent f,
int direction)
This methods is normally called when the user has indicated that they will begin resizing the frame. |
void |
closeFrame(JInternalFrame f)
Removes the frame, and, if necessary, the desktopIcon, from its parent. |
void |
deactivateFrame(JInternalFrame f)
Generally, indicate that this frame has lost focus. |
void |
deiconifyFrame(JInternalFrame f)
Removes the desktopIcon from its parent and adds its frame to the parent. |
void |
dragFrame(JComponent f,
int newX,
int newY)
Moves the visible location of the frame being dragged to the location specified. |
void |
endDraggingFrame(JComponent f)
This method signals the end of the dragging session. |
void |
endResizingFrame(JComponent f)
This method signals the end of the resize session. |
protected Rectangle |
getBoundsForIconOf(JInternalFrame f)
The iconifyFrame() code calls this to determine the proper bounds for the desktopIcon. |
protected Rectangle |
getPreviousBounds(JInternalFrame f)
Gets the normal bounds of the component prior to the component being maximized. |
void |
iconifyFrame(JInternalFrame f)
Removes the frame from its parent and adds its desktopIcon to the parent. |
void |
maximizeFrame(JInternalFrame f)
Resizes the frame to fill its parents bounds. |
void |
minimizeFrame(JInternalFrame f)
Restores the frame back to its size and position prior to a maximizeFrame call. |
void |
openFrame(JInternalFrame f)
Normally this method will not be called. |
protected void |
removeIconFor(JInternalFrame f)
Convenience 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)
Returns true if the component has been iconized
and the bounds of the desktopIcon are valid,
otherwise returns false. |
