Controllers in OpenOffice.org are between a frame and document model. This is their basic role as expressed in com.sun.star.frame.XController, which has methods getModel() and getFrame(). The method getFrame() provides the frame that the controller is attached to. The method getModel() returns a document model, but it may return an empty reference if the component does not have a model.
Usually the controller objects support additional interfaces specific to the document type they control, such as com.sun.star.sheet.XSpreadsheetView for Calc document controllers or com.sun.star.text.XTextViewCursorSupplier for Writer document controllers.
There can be more than one controller instance with frames of their own controlling the same document model simultaneously. Multiple controllers and frames are created by OpenOffice.org when the user clicks Window - New Window.
