Part 1 - Classes and Methods / ODPart

ViewTypeChanged

The ViewTypeChanged method is called to notify this part that the view type of one of its display frames has changed.

void ViewTypeChanged (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 view type.

Your part's ViewTypeChanged method should examine the new view type using its frame's GetViewType method. It should then display itself in the specified display frame according to the indicated view type. If your part does not support the requested view type, it should instead pick a view type that it can support and then call its frame's SetViewType method to update the view type 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.
