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:



public CTabItem(CTabFolder parent, int style)
public CTabItem(CTabFolder parent, int style, int index)





Cannot close CTabItem

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
