Question on viewing html content [message #174755]

I am building an Eclipse plug-in for managing a knowledge base. This
involves
storing html-files in a database and viewing them in Eclipse.

Let's say I have a string buffer which contains a HTML document. How
can I show it in an Eclipse view? I would like to show plain text (as in a
web
browser) not hml source code. I don't want to create a temporary
file on hard disk.

I can show contents of the buffer in a TextViewer, but this obviously
shows it as it is (=html source code) and not as as in a web browser.

The document does not contain hyper links or references to other files.
I could create a parser and remove all html tags from the string buffer
before showing it. But do you know a smarter way to atchieve what I need?

All answers are highly appreciated.

Thank you in advance.

Katja

ps. If my question was not clear, let me know.

Im probably not the best expert in this but there is an internal browser
you can launch. You could post the stream to that perhaps.

Many thanks for your reply. I have already been looking at the class =
org.eclipse.ui.browser.IWebBrowser, which
I suppose is what you had in mind too. The interface only provides =
method "open_url" which takes java.net.URL as an input
parameter. I'm a complete newbie on the area, but I'll try to see if I =
could use data URI scheme to pass my string to the browser...

Hi Katja

You are right, there is only a space for a url. I dont know why they would
do this perhaps this is a requirement of the browser. Ive been told you
can be sneaky and jam the html in through the widget. Im not sure this is
the right answer.

I guess using a temp file would be out of the question :(

The SWT Browser widget is probably what you were thinking of, as it
can take a simple string for display.

The SWT widget (org.eclipse.swt.browser.Browser) is indeed what I am =
looking for.
Many thanks to both of you for replying and helping an Eclipse newbie.=20
