nsXULScrollFrame Class Reference

#include <nsGfxScrollFrame.h>

Inheritance diagram for nsXULScrollFrame:

nsIAnonymousContentCreator nsContainerFrame nsISupports nsISupports nsISupports nsFrame nsIFrame nsISupports

List of all members.


Detailed Description

The scroll frame creates and manages the scrolling view

It only supports having a single child frame that typically is an area frame, but doesn't have to be. The child frame must have a view, though

Scroll frames don't support incremental changes, i.e. you can't replace or remove the scrolled frame
