- This viewkit component provides a means for application which would like
- to provide web access from within the application. Many reasons for
- providing such access may have little to do with the web "per se." For
- example, this component can be used with a form and the post method to

- obtain a license for a user from a local or remote server. The component
- can be used to format text and images in a purely read-only fashion, or
- could be used to provide help to the user. See also VkWebViewerBase.
-
- The viewer maintains a stack of visited links which can be navigated, a
- cache which holds images and pages visited and which purges pages on a
- least recently used basis, and a set of UI controls thought to be
- familiar to the web user. The viewer provides an API which allows the
- programmer to control these features and uses a small number of X
- resources to control the aspects of the viewer which are modifiable by
- the programmer.

- The visited URLs form a stack. By calling navigate, you can move through
- the stack. The values for direction are:
-
- SG_FIRST,
- SG_LAST,
- SG_PREV,
- SG_NEXT

- The visited URLs form a stack. By calling navigate, you can move through
- the stack. This form of navigate lets you go directly to a particular
- item on the stack. getStackDepth() can be used to find the upper bound on
- index.

- This method allows the programmer to control the UI shown. If this is
- true (the default) then all the controls are shown. If false, a more
- minimal set is shown. This method is primarily for use with the media
- warehouse's media viewer component. This can also be controlled by the
- resource "controls".

- This method returns the current upper bound on the visited URL stack.
- The stack includes all URLs visited including the one currently being
- viewed. The current URL being viewed is at the stack depth less one.
