Java/SWT GUI Access from Thread

A thread in Java cannot directly access the GUI. With the following snippet the access is possible:

Call from the thread:

@Override
public void run() {
    html = "<h1>Huhu</h1>";
    dlg.setSomeStuffToGui(html);    
}

Method in the GUI:

public void setSomeStuffToGui(final String html) {
    Display display = getDisplay();

    display.asyncExec(new Runnable() {
        public void run() {
            //your stuff goes here:
            textField.setText(html);
        }
      });           
}
