The BJC Multiple Document Interface (BJC MDI) has been designed to make it easier to develop windowing system for multiple documents with Macromedia Flash. The content documents of the BJC MDI windows can be added by their linkage id when they are located in the item library of the stage. The content documents can also be loaded from external sources such as different swf-files or images.

Adding windows with the BJC MDI component parameters is also possible. The BJC MDI component includes such features as desktop icons, message boxes and menus.

This component is fully ActionScript controllable.
