com.vlsolutions.swing.docking.event.DockableStateWillChangeEvent

An event triggered before a change of dockable state.

Events are triggered when a component is :

Docked (added to the desktop)
set in Auto-hide mode (collapsed as a border button)
closed (removed from the desktop)
maximized
floating (detached from its window)

Note that event are not triggered by drag-dock moves (they don't correspond to a state change). If you need to track such changes, use a Swing AncestorListener, or override the addNotify method of your dockable component.

It is also possible to track changes after they occur with the DockableStateChangeEvent . @see javax.swing.event.AncestorListener @see DockableStateWillChangeListener @author Lilian Chamontin, vlsolutions. @version 1.0

            // in this context, the drag event can only be generated by a hidden dockable
            // (if there is a way to drag its button) or an already docked dockable (no state change)
            if (currentState.getLocation() != futureLocation) { // state cannot be null
                this.stateChange = true;
                DockableState newState = new DockableState(umInfo.desktop, dockable, futureLocation);
                DockableStateWillChangeEvent dscwEvent =
                        new DockableStateWillChangeEvent(currentState, newState);
                if (!desktop.getContext().fireDockableStateWillChange(dscwEvent)) {
                    return false;
                }
            }


            if (currentState == null) {
                return false; // safety check as is shouldn't be the case
            }


            DockableStateWillChangeEvent dscwEvent = new DockableStateWillChangeEvent(currentState, newState);
            //
            if (!desktop.getContext().fireDockableStateWillChange(dscwEvent)) {
                return false;
            } else {
                // also trigger DockingAction
