Re: [platform-swt-dev] trivial work about setting layout data -- need im

[Carolyn MacLeod <Carolyn_MacLeod@xxxxxxxxxx>]

One other possibility is to use the
LayoutExample to do some of the work for you.
Here's how to get all of the SWT examples:
http://www.eclipse.org/swt/examples.php
Then run the LayoutExample, choose the
layout type you think you want to use, add the controls that you want in
your layout, and lay them out the way you want by changing various layout
data values in the table.
Then click the Generate Code button.
Copy/paste the generated code into your code.
It's really primitive, but it could
be helpful.

Alternatively, you can try out one of
the available GUI builders: http://www.eclipse.org/swt/faq.php#guibuilder

Hope this helps,
Carolyn

Hi Shwan:

Yes, that's what I need, although this necessary functionality exists
in JFace other than SWT.

Then thank you very much.
