Overview

This protocol is adopted by the document view of a WebFrameView. You can extend WebKit to support additional MIME types by implementing your own document view and document representation classes to render data for specific MIME types. You register those classes using the WebFrame registerViewClass:representationClass:forMIMEType: method. Classes that adopt this protocol are expected to be subclasses of NSView.

setNeedsLayout:

Sets whether or not the receiver should change its layout.

- (void)setNeedsLayout:(BOOL)flag
Parameters
flag

Sets whether the receiver needs to update its layout in the next call to its drawRect: method.

Discussion

A view conforming to this protocol should store the most recent value of this flag in an internal variable. Then, in its drawRect method, if the most recent value of this flag was YES, it should invoke layout and reset the internal variable before updating the contents of the view.
