PresentationChanged

Inside Macintosh: OpenDoc Class Reference /: Part 1 - Classes and Methods / ODPart

PresentationChanged
The PresentationChanged method is called to notify this part that the presentation of one of its display frames has changed.
void PresentationChanged (in ODFrame frame);
frame
A reference to a display frame for this part.

DISCUSSION
OpenDoc calls this method when this part's display frame changes its presentation.
Your part's PresentationChanged method should examine the new presentation using its frame's GetPresentation method. It should then display itself in the specified display frame according to the indicated presentation. If your part does not support the requested presentation, it should instead pick a presentation that it can support and then call its frame's SetPresentation method to update the presentation in the frame.

OVERRIDING
When you subclass ODPart, you must override this method. Your override method must not call its inherited method; that is, your override method must implement this method's functionality completely.

EXCEPTIONS

kODErrInvalidFrame
The specified frame is not a display frame of this part.
