How can I specify the minimum size for a TreeViewer within a form's
ExpandableComposite Section?

I'd like to say "TreeViewer shall be at least 12 lines high".

Ed,

I found that in a dialog box I had to configure the grid data and use it to
set the underlying tree layout data. This was done for me automatically when
using the same TreeViewer from within a view.

protected Control createDialogArea(Composite parent) {
Composite area = (Composite) super.createDialogArea(parent);
area.setBounds(0, 0, 800, 800);
GridData data = new GridData(GridData.FILL_BOTH);
data.widthHint = convertWidthInCharsToPixels(60);
data.heightHint = convertHeightInCharsToPixels(18);
final TreeViewer viewer = new TreeViewer(area, SWT.MULTI | SWT.H_SCROLL
| SWT.V_SCROLL);
viewer.setContentProvider(new ViewContentProvider());
viewer.setLabelProvider(new ViewLabelProvider());
viewer.setInput(area);
viewer.setAutoExpandLevel(2);
viewer.expandToLevel(2);
Tree treeWidget = viewer.getTree();
treeWidget.setLayoutData(data);
treeWidget.setFont(area.getFont());
return (area);
}
