Re: [platform-ua-dev] accessing embedded browser in an RCP help app

[Chris Goldthorpe <cgold@xxxxxxxxxx>]

Hi Todd,

I noticed some comments in  https://bugs.eclipse.org/bugs/show_bug.cgi?id=57331,
comments 3 and 12 suggesting  a way to close the help system. I experimented
with this a little and it appears that it would work as long as the application
then exits after the browser is closed. We don't have any public API for
shutting down the help system or listening to events from the help browser
so to achieve what you want using Eclipse 3.3 you would need to hack the
source code a little and use internal APIs. If you come up with something
that works for you I'd be interested to see a patch of your changes (you
could attach them to the bug). If enough people request a particular extension
to the API we can add it in a future release.

Subject	[platform-ua-dev] accessing embedded browser in an RCP help app

Hi there,
Wondering if someone here has run into the problem that I'm facing...
We've got an RCP app whose sole purpose is delivery of 'Online Help' via
a
CDROM. The entire app is composed of a single plugin (the RCP app) which
depends on all of our existing user.doc plugins.

The RCP app starts up with essentially an empty workbench (we hide the
window, so it appears headless) and simply opens the system help which
in
turn loads our doc plugins. ie -

      //start up the help system to display the help content
      IWorkbenchHelpSystem helpSystem;
            helpSystem = PlatformUI.getWorkbench().getHelpSystem();
            helpSystem.displayHelp();

The problem is that, once the help window is opened, and the user
subsequently closes it, the workbench (javaw) process is of course left
running.
Since this is product is delivered pretty much exclusively to windows
users, thus we can be relatively certain that it's going to use the
embedded swt browser, I'm wondering if there's a way to access the embedded
swt browser programmatically to add a window close listener which will
close the workbench as well? The desired result is that I want the action
of closing the help browser window to make the help system exit cleanly.

Anybody got any suggestions? If there's a better way to accomplish what
I'm
talking about, feel free to recommend an alternate method - I'm still
getting the feel for eclipse, so I'm sure there's LOTS of places where
I've
yet to scratch the surface ;)

Thanks,
Todd
