Hi there,

Many thanks -- do you know when you'll be adding XHTML support? XHTML

1.1 is actually much easier to work with than old HTML specs in that the

structures and tag set are simpler, and documents are more regular.

I can live with import and export of HTML, and I don't need JavaScript

to work inside the TRichView; I just need to be able to insert hidden

tags or annotations that will enable me to link the resulting anchors to

JavaScript functions. For example, is it possible to insert a link like

this:

I don't need the JavaScript function to execute in the context of

TRichView; I just need it to be inserted programmatically, so when I

export to HTML (and add the appropriate JavaScript code to the result)

it will work. (Basically, in my app, my users annotate a document, then

produce HTML output that enables a reader to view the annotations in a

browser.)

One more question: how does copy/paste work? For example, if my user has

a Web page open in IE, and selects and copies the document to the

clipboard, then pastes into a TRichView, what will result? Will any of

the styles and formatting come over via RTF, or will it just be plain text?

Cheers,

Martin
