Examples of org.flexdock.docking.DockingStrategy

org.flexdock.docking.DockingStrategy
This interface defines an API used by {@code DockingManager} and{@code DockingPort} to support customizable behaviors during dockingoperations. {@code DockingManager} will associate a {@code DockingStrategy}with a particular {@code DockingPort} or {@code Dockable} class type. Callsto {@code DockingManager.dock()} and {@code DockingManager.undock()} will bedeferred to the {@code DockingStrategy} associated with the parameterssupplied in the respective method calls. {@code DockingStrategies} are alsoresponsible for creating sub-DockingPorts and split panes for nested {@code DockingPorts}Implementations of {@code DockingStrategy} are responsible for managingcomponent relationships between {@code Dockables} and parent containers. Thisincludes making determinations as to whether a particular docking operation will be allowed for the specified parameters and the specifics of how a particular {@code Dockable} may be removed from one parent{@code Container} or {@code DockingPort} and added to another.{@code DockingStrategy} may determine whether a call to {@code dock()}implies an attempt to float a {@code Dockable} in a separate window.Because of the potentially large scope of responsibilities associated with a {@code DockingStrategy}, implementations may range from being very simple to highly complex. Although custom implementations of {@code DockingStrategy}are not discouraged, the recommeded path is to subclass {@code DefaultDockingStrategy} for consistency of behavior.{@code DockingStrategies} are associated with a particular type of{@code Dockable} or {@code DockingPort} by calling{@code DockingManager.setDockingStrategy(Class c, DockingStrategy strategy)}. {@code DefaultDockingStrategy} is the default implementation used for allclasses that do not have a custom {@code DockingStrategy} registered. @author Christopher Butler
