Returns:

the owner of this strategy

install

public void install(Component container)

hierarchyChanged

public void hierarchyChanged(DockHierarchyEvent event)

Description copied from interface: DockHierarchyListener

Called when the path of the observed Dockable has been changed.

Specified by:

hierarchyChanged in interface DockHierarchyListener

Parameters:

event - the new path

controllerChanged

public void controllerChanged(DockHierarchyEvent event)

Description copied from interface: DockHierarchyListener

Invoked whenever the controller of dockable has changed

Specified by:

controllerChanged in interface DockHierarchyListener

setCursor

protected void setCursor(Cursor cursor)

Changes the cursor of the base component. Subclasses may override this method to use custom cursors.

Parameters:

cursor - the cursor to set, may be null

repaint

protected void repaint(int x,
                       int y,

Parameters:

x - x coordinate

y - y coordinate

width - the width of the are to repaint

height - the height of the are to repaint

getDividerNode

protected Divideable getDividerNode(int x,
                                    int y)

Gets the node whose divider contains x, y.

Parameters:

x - the x coordinate

y - the y coordinate

Returns:

the node containing x, y

checkMousePositionAsync

protected void checkMousePositionAsync()
