I have a code that generates a UI using SWT.

In this UI, there is a toolbar and and one of the icons in the toolbar should open a folder when you click on it.

How can I set this icon to open a folder when you click on it?

I am sending the code below:

import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.CTabFolder;
import org.eclipse.swt.custom.CTabItem;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;

import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
