Question

I’m using a CTabFolder to let the user edit a group of elements.

However, there is some data-dependency between some tabs (CTabItems) which requires me to re-load the content of a tab when its content is shown. (How) Is it possible to do that?

Answer 1

You can attach a SelectionListener to the CTabFolder and exchange the control of your CTabItem there.

Let’s assume you want to exchange the content of the second tab when the user selects it:

        folder.addSelectionListener(new SelectionAdapter() {

        @Override
        public void widgetSelected(final SelectionEvent arg0) {
            if (folder.getSelectionIndex() == 1) {
                Text text = new Text(folder, SWT.MULTI);
                text.setText("foobar");
                folder.getItem(1).setControl(text);
            }
        }
    });
