    public interface DropFilter

    Interface for filtering drops when a drag and drop is in progress.

    There are 4 kinds of drop types, see SplitDropInfo, ChildDropInfo, InteriorDropInfo and InsertTabDropInfo.

    A drop filter is used to filter drops. The filter may decide if a drop of a window into another window is to be accepted or not. This makes it possible to tailor the drop behavior of a DockingWindow. The window (called drop window) into which another window is beeing dropped is asked if it will accept a drop of that window. The filter is asked continuously during a drag operation i.e. it may be asked many times during a drag operation.
