Query support for Table of Contents.

Pascal
function CanShowTableOfContents: Boolean;
C++
__fastcall Boolean CanShowTableOfContents();
Description

The Help System uses CanShowTableOfContents to determine which Help Viewers know how to display a Table of Contents. CanShowTableOfContents should return true if the Viewer is ready for a subsequent call to ShowTableOfContents. The Help System should not call ShowTableOfContents for a Viewer after CanShowTableOfContents returns false; if this occurs, the Viewer should raise an EHelpSystemException.
