New User problem: resizing panels [message #458523] Thu, 14 July 2005 14:09 Go to next message

Originally posted by: epetrone.bellsouth.net

I'm still fairly new to creating SWT GUIs and am having a problem with my
panels that I'm sure is something trivial, but I've not been able to solve
it.

If I put all my widgets as direct children of the application shell, then
with I resize the window the widgets adjust as I expect them too (text
fields get wider, etc). However, if I create a layer of composites as
children of the shell (to create more complex layouts), and make the
widgets children of the various composites, I lose the resizing. The outer
shell will resize, but the content (composites and widgets both) seem to
maintain their original size.

I'm sure I've either added something to the code that is interfering with
the resizing or have forgotten to add some snippet of code that is required.
Any thoughts?

Thanks,
Elaine

Controls are either explicity positioned during resize by application code
(using Control.setBounds()) or by layouts (see the hierarchy Layout and
Composite.setLayout()). If neither of these mechanisms are used, then a
control will not move. There is an in depth article on SWT layouts
available on Eclipse.org.

Hi

The resizing behavior will now depend on the Layout you have given to the
composites that host your widgets
