If you recall, field-level help was implemented by clicking
on a Question mark icon on the top right in the title bar. Your
cursor changed to a Question Mark and pointer, and clicking on a
field, button or other control would evoke a popup.
You can duplicate that functionality, but the lions's share
of the work would be on the developers. You can provide the small
blurbs, but how it is called is up to them.
The API is useful if you might change topic ids often, or if
you need a sort of map file, or if you just want a standard way of
calling Webhelp into a certain window format. But you don't need
the two-pane format instructions for 'What's This' help.
So, your developer will have to add a function to each page
so that, if the user changes the cursor to a 'What's This' curson,
and an object is clicked during this 'What's This' state, an
explanatory popup will, um, pop up.
...Otherwise, everything behaves normally.
