Class DefaultMagnetStrategy

java.lang.Object
  bibliothek.gui.dock.station.screen.magnet.DefaultMagnetStrategy

All Implemented Interfaces:

MagnetStrategy

public class DefaultMagnetStrategy
extends Object
implements MagnetStrategy

The DefaultMagnetStrategy is based on the DefaultMagnetOperation. It searches the nearest attracted ScreenDockWindow to a moved side and if that other window is nearer than a given threshold then the moved window is attracted.

Method Summary

int	getThreshold() Tells how many pixels two sides can be appart and still attract each other.
void	install(MagnetController controller) Informs this MagnetStrategy that it will be used by controller.
void	setThreshold(int threshold) Sets how many pixels two sides can be appart and still attract each other.

Constructor Detail

DefaultMagnetStrategy

public DefaultMagnetStrategy()

Method Detail

setThreshold

public void setThreshold(int threshold)

Sets how many pixels two sides can be appart and still attract each other.

Parameters:

threshold - the maximal distance, at least 1

getThreshold

public int getThreshold()

Tells how many pixels two sides can be appart and still attract each other.

Returns:

the maximal distance, at least 1

install

public void install(MagnetController controller)

Description copied from interface: MagnetStrategy

Informs this MagnetStrategy that it will be used by controller.

Specified by:

install in interface MagnetStrategy

Parameters:

controller - the controller using this strategy, not null

uninstall

public void uninstall(MagnetController controller)

Description copied from interface: MagnetStrategy

Informs this MagnetStrategy that it is no longer used by controller.

Specified by:

uninstall in interface MagnetStrategy

Parameters:

controller - the controller which no longer uses this strategy

start

public MagnetOperation start(MagnetController controller,
                             MagnetRequest request)

Description copied from interface: MagnetStrategy

Called by controller after a ScreenDockWindow moved or changed its size (or both). This method creates a new MagnetOperation which is tied to request. The MagnetOperation will then find out which Dockable is attracted to which other Dockable.

Specified by:

start in interface MagnetStrategy

Parameters:

controller - the caller of this method, may be used to find other ScreenDockWindows

request - detailed information about the event
