Hi,

I have been testing with RAP and I took the TreeViewer example from the
demo site and have been making changes to it. I am having a problem where
that I want to add a Text field above my TreeViewer, so I have done the
following;

Composite contents = new Composite(parent, SWT.HORIZONTAL);
contents.setLayout(new GridLayout(1,false));
Text inputText = new Text(contents, SWT.BORDER);
inputText.setLayoutData(
new GridData(GridData.FILL_HORIZONTAL));
viewer = new TreeViewer(contents);

and the Input text expands to fill the screen, but not the TreeViewer.
However there is no method for "setLayoutData" on the Treeviewer, so I
can't expand it that way, and at the moment its crunched up on the left.

(2nd question - whats the difference between the SWT Tree widget and the
jface TreeViewer, can either be used, or one rather than the other?)

Many Thanks,

Tom

Ah, almost immediately after posting that, is discovered;

viewer.getTree().setLayoutData(new GridData(GridData.FILL_BOTH));

!!!

The question on the difference between the jface and the swt widgets still
stands though?

So I should be using jface toolkit objects in preference to SWT widgets
when available?

yes, in most cases you will be better off using JFace.
