launch help url in internal browser [message #469593]

I can launch a help topic by doing the following:
PlatformUI.getWorkbench().getHelpSystem().displayHelpResourc e(myDocHref);

However that always has the Help System navigation frame. I want just the
topic.

I can get the URL for just the topic as follows:
URL url = PlatformUI.getWorkbench().getHelpSystem().resolve(myDocHref,
true);

(the second arg 'true' says the document only...without navigation frame)

Is there any way to launch that URL in the 'help browser'...meaning the
eclipse browser, with no tool bar/address bar/etc.

If I do:
PlatformUI.getWorkbench().getBrowserSupport().createBrowser( "myBrowser").openURL(url);

I get a firefox window.

I want to be able to launch the help browser with just a topic. I think I
could do my own browser implementation with a Browser widget...but it
would be much easier if I could just use the same 'internal' browser that
help uses to show any url.

Thanks for any suggestions...

If you add the parameter noframes=true that will suppress the frame
generation. For example
http://help.eclipse.org/help33/topic/org.eclipse.platform.do c.user/tips/platform_tips.html?noframes=true

will give a different result than what you would get if you left off the
noframes parameter.

Thanks for the reply. In your example you are appending the noframes arg
to a URL. To accomplish what I'm trying to accomplish, I would have to be
able to append it to the href in order to launch in the 'help browser'
PlatformUI.getWorkbench().getHelpSystem().displayHelpResourc e(href+ "?noframes=true");
but this results in "An exception occurred while launching help"

I can get an appropriate URL generated...but if I launch the URL myself,
it is in a real broswer window (Firefox, IE). I want to launch in an
'eclipse browser' like the help system does with a displayHelpResource
call...a non-branded browser.

So I guess maybe my question can be taken out of the context of help. How
would I launch any URL in a non-external browser?

Thanks,
Scott

Off the top of my head I don't know the answer to that one - I haven't
tried to use the help browser to open anything other than the help system.

digging into the code a little, it looks like you should be able to
specify ?noframes=true on an href. However, specifying that forces the
help to launch in an external browser anyhow. So...I think what I want to
do is not possible through the help system. Thanks.
