Question

I put three composite(1,2,3) inside one composite0, so they all set their layout based on the composite0.setLayout(new FormLayout()). The problem I have now is, I make the composite3 invisible: composite3.setVisible(false); (I dont want to delete the data, still need that component, but just doesn’t want it shows on the UI), and there’s a big gap after componite2 now. How to remove the big gap(which use to put the composite2)? thank you in advanced!

Answer 1

        FormData data = new FormData();
        data.left = new FormAttachment(0, 100, EditorPanel.SPACING);
        data.top = new FormAttachment(section1, EditorPanel.SPACING);
        data.height = 0;
        data.width = 0;
        addSectionFormData(a, b, c);
        a.setLayoutData(data);
        b.setLayoutData(data);

this solve the problem! 🙂
