Example 11 with DropTargetDropEvent

use of java.awt.dnd.DropTargetDropEvent in project GCViewer by chewiebug.

Example 12 with DropTargetDropEvent

use of java.awt.dnd.DropTargetDropEvent in project jna by java-native-access.

the class DropHandler method getDropAction.

/** Calculate the effective action.  The default implementation 
     * checks whether any {@link DataFlavor}s are supported, and if so,
     * will change the current action from {@link DnDConstants#ACTION_NONE} to 
     * something in common between the source and destination.  Refuse 
     * user-requested actions if they are not supported (rather than silently 
     * accepting a non-user-requested action, which is the Java's DnD default 
     * behavior).  The drop action is forced to {@link DnDConstants#ACTION_NONE} 
     * if there is no supported data flavor.
     * @param e {@link DropTargetEvent}
     * @return effective drop action
     * @see #isSupported(DataFlavor[])
     * @see #getDropActionsForFlavors
