Adding CTabItems
Because no styles apply, pass SWT.NONE for the style. Optionally, you can pass an index to specify the zero-based order of the tab. The constructors are as follows:
<source lang="java">
public CTabItem(CTabFolder parent, int style) public CTabItem(CTabFolder parent, int style, int index)</source>
Cannot close CTabItem
<source lang="java">
import org.eclipse.swt.SWT; import org.eclipse.swt.custom.CTabFolder; import org.eclipse.swt.custom.CTabFolder2Adapter; import org.eclipse.swt.custom.CTabFolderEvent; import org.eclipse.swt.custom.CTabItem; import org.eclipse.swt.layout.FillLayout; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; import org.eclipse.swt.widgets.Text; public class CTabItemCannotClose {
public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); shell.setLayout(new FillLayout()); CTabFolder folder = new CTabFolder(shell, SWT.BORDER); for (int i = 0; i < 4; i++) { CTabItem item = new CTabItem(folder, SWT.CLOSE); item.setText("Item " + i); Text text = new Text(folder, SWT.MULTI); text.setText("Content for Item " + i); item.setControl(text); } final CTabItem specialItem = new CTabItem(folder, SWT.CLOSE); specialItem.setText("Don"t Close Me"); Text text = new Text(folder, SWT.MULTI); text.setText("This tab can never be closed"); specialItem.setControl(text); folder.addCTabFolder2Listener(new CTabFolder2Adapter() { public void close(CTabFolderEvent event) { System.out.println("want to close"); if (event.item.equals(specialItem)) { event.doit = false; } } }); shell.pack(); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); }

No Close Button CTabItem
