Re: [platform-swt-dev] Problem in Caturing excel events form SWT
|
I have never tried to get the sheet activation events for Excel. However,
this may help:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet123.java?rev=HEAD&content-type=text/vnd.viewcvs-markup
This snippet shows how you can set a property and get event notification.
If this does not help, post the IDL for the events you are trying to get.
