Hi, I have a tab in which I publish a list. I would like to be able to access and modify my list from the tab.

For example please see that code bellow :

        public void createControl(Composite parent) {
                Composite container = new Composite(parent, SWT.NULL);
                GridLayout layout = new GridLayout(3, false);
                tabfolder = new CTabFolder(container, SWT.BORDER | SWT.MULTI);
                CTabItem tab= new CTabItem(tabfolder, SWT.CLOSE);
                tab.setControl( createTabContent( tabfolder ));

private Composite createTabContent( Composite parent ) {
                Composite c = new Composite( parent, SWT.NONE );
                c.setLayout( new GridLayout( 2, false ));
                List list=new List(c, SWT.MULTI | SWT.V_SCROLL);
                GridData gd = new GridData();
                gd.horizontalAlignment = SWT.FILL;
                gd.grabExcessVerticalSpace = true;
                for (int i=0; i<3; i++) list.add ("Item " + i);
                return c;

Is there a way to access and modify the list from the tab ?

for example :

List myList = (List) tab.function_to_access_list()

Thanks for your help

CTabItem#getControl() will return the control that you set with #setControl(). But you should hold on to your list in a field.
