    copied!<p>I have <code>ScrolledComposite</code> which allows only vertical scrolling. (heighthint = 400)</p> <p>Within this ScrolledComposite, I have another <code>CompositeA</code> (height may exceed 400 for scrolling) to store all other widgets.</p> <p>I have a very long label (with <code>SWT.WRAP</code> enabled). But instead of wrapping, it is always showing in a single line. I want this label to wrap according to the width of its parent (<code>CompositeA</code>)</p> <p>I forgot to add that this <code>CompositeA</code> is a 2 column 'GridLayout' with <code>makeColumnsEqualWidth = true</code></p> <p>EDIT: This is my code.</p> <pre><code>public void createPartControl(Composite parent) { // TODO Auto-generated method stub Display display = parent.getDisplay(); toolkit = new FormToolkit(display); form = toolkit.createForm(parent); form.setText("ABC"); Composite body = form.getBody(); TableWrapLayout layout = new TableWrapLayout(); layout.numColumns = 2; body.setLayout(layout); Label header1 = toolkit.createLabel(body, "ABC: "); Font font = new Font(display, "Arial", 11, SWT.BOLD); header1.setFont(font); Label header2 = toolkit.createLabel(body, "XYZ", SWT.WRAP); font = new Font(display, "Arial", 11, SWT.NONE); header2.setFont(font); TableWrapData wd = new TableWrapData(TableWrapData.FILL_GRAB); header2.setLayoutData(wd); form.getBody().setBackground( form.getBody().getDisplay() .getSystemColor(SWT.COLOR_WIDGET_BACKGROUND)); // Scrolled composite ScrolledComposite sc = new ScrolledComposite(body, SWT.BORDER_SOLID | SWT.V_SCROLL); sc.setAlwaysShowScrollBars(true); sc.setBackground(new Color(display, 50,255,155)); wd = new TableWrapData(TableWrapData.FILL); wd.heightHint = 360; wd.colspan = 2; wd.grabHorizontal = false; sc.setLayoutData(wd); sc.setLayout(new TableWrapLayout()); Composite innerComposite = toolkit.createComposite(sc); sc.setContent(innerComposite); innerComposite.setLayout(new TableWrapLayout()); innerComposite.setBackground(new Color(display, 255,50,50)); Section section = toolkit.createSection(innerComposite, Section.DESCRIPTION | Section.TITLE_BAR | Section.EXPANDED); wd = new TableWrapData(TableWrapData.FILL); wd.maxWidth = 600; // don't want to hardcode this value section.setLayoutData(wd); section.setText("Section"); section.setDescription("A not so long description......................"); // Composite for Section Composite sectionClient = toolkit.createComposite(section); layout = new TableWrapLayout(); layout.numColumns = 2; layout.makeColumnsEqualWidth = true; sectionClient.setLayout(layout); toolkit.createButton(sectionClient, "Button 1", SWT.RADIO); Label rightDesc = toolkit .createLabel( sectionClient, "A very long long long long long long long long long long long long long long long long long long long long desc that needs wrapping", SWT.WRAP); font = new Font(display, "Arial", 10, SWT.ITALIC); rightDesc.setFont(font); wd = new TableWrapData(); wd.rowspan = 2; rightDesc.setLayoutData(wd); Combo comboDropDown = new Combo(sectionClient, SWT.DROP_DOWN | SWT.BORDER); comboDropDown.setText("DDL"); comboDropDown.add("1"); comboDropDown.add("2"); comboDropDown.add("3"); Label lineBreak = toolkit.createSeparator(sectionClient, SWT.SEPARATOR | SWT.HORIZONTAL); wd = new TableWrapData(TableWrapData.FILL); wd.colspan = 2; lineBreak.setLayoutData(wd); /***********************/ toolkit.createButton(sectionClient, "Button 2", SWT.RADIO); Label rightDesc2 = toolkit .createLabel( sectionClient, "A long long long long long long long long long long long long long long long long long long long long desc that needs wrapping", SWT.WRAP); font = new Font(display, "Arial", 10, SWT.ITALIC); rightDesc2.setFont(font); wd = new TableWrapData(TableWrapData.FILL); wd.rowspan = 3; rightDesc2.setLayoutData(wd); toolkit.createLabel(sectionClient, "Desc", SWT.WRAP); toolkit.createText(sectionClient, "hello world", SWT.NONE); section.setClient(sectionClient); innerComposite.pack(); } </code></pre> <p>If you run it, you can see a green scrolledcomposite and a red composite.
