Hallo,
I tried to create "Tabbed property" with Clabel, button and Ccombo object. I
have created this object:
Composite composite = getWidgetFactory().createFlatFormComposite(parent);
CLabel fitnessFunctionLabel =
getWidgetFactory().createCLabel(composite, "aaa");
CCombo fitnessFunctionCombo = getWidgetFactory().createCCombo(parent);
Button changeButton = getWidgetFactory().createButton(composite,
"bbb", SWT.PUSH);
and after that I try to configure their positions. Everything is OK except:
data = new FormData();
data.left = new FormAttachment(0, 150);
fitnessFunctionCombo.setLayoutData(data);
I hava an exception:
ava.lang.ClassCastException: org.eclipse.swt.layout.FormData cannot be cast
to org.eclipse.swt.layout.FillData
Can I use formData to Ccombo or should I use somethig else?
regards
Janusz

Hi Grant,
Thank's. Now it is working. I used example from "The Eclipse Tabbed
Properties View" article and there was everything OK (without Ccombo)
