[news.eclipse.platform.swt] how to detect if the cursor is on a bold tex

["asra" <asra.choukri@xxxxxxxxxxxxxx>]

Hi!

Anyone knows how to detect if the cursor is on a bold text in an ActiveX
"DHTMLEdit.DHTMLEdit".
 This program should return me the status of the current text  when I click
on the button "State".  But that does not go.

Any ideas ?
Thanks.
