Hi everybody,

I'm trying to create a property sheet using eclipse forms. The property
sheet should print documentation for objects selected. The documentation
could be quite long and should wrap automatically. Well and here is the
problem it does not. I've tried a lot of stuff but nothing seams to
work. I am already wondering if it is possible or not. Here is some code
I wrote:

public void createControls(Composite parent,
final TabbedPropertySheetPage atabbedPropertySheetPage) {
super.createControls(parent, atabbedPropertySheetPage);

toolkit = new TabbedPropertySheetWidgetFactory();
form = toolkit.createForm(parent);
form.setText("Documentation");

TableWrapLayout descriptionLayout = new TableWrapLayout();
descriptionLayout.numColumns=1;
form.getBody().setLayout(descriptionLayout);

TableWrapData twd = new TableWrapData();
twd.colspan=1;
twd.grabVertical=true;
twd.grabHorizontal=true;

String t = "dhfjsfhk hfdskj fhjksd fhdsjkf hjkhjkhfdsjhk
hfjdshhjkhdfs hfdsjhfdj fhdjfh sdhfjdhjfdskhjfdsh hfdjskhf dsjkjhfdjsk h
hfdskjhfdjsh hjkfsdh fdhjkshfdskjhfdsj hjfdskhf dshjfksdhf sdjk";

FormText text = toolkit.createFormText(form.getBody(), false);
text.setText(t, false, false);
text.setLayoutData(twd);
}

No mater what widget I take the long text t is not wrapped :(

Regards
Martin

I jut tried inserting most of your your sample code into a plug-in with a view and it worked fine. I think the problem is that the parent does not have width preference and get's it's width from the Form, which in turn gets it's width from the FormText.

If the parent composite had it's width specified then that width would get propagated down to it's descendents, however I'm guessing that in your example the parent has no width preference so it allows it's children to be their preferred size.

Well, my understanding is that I don't have an influence on the parent,
since this is the section of a propertyTab. I also read somewhere, that
the TableWrapLayout doesn't work as expected (wrapping the control) if
one of the Parents has the GridLayout, So I was already wondering if a
property section would have that layout avoiding that my wrapping works
fine ... :(

Can you give instructions on how to create a test case that illustrates the problem? There are definitely situations where TableWrapLayout and GridLayout do not work well together.
