title: Java RCP - Not able to dynamically set text to SWT label control
body: <p>In one of our rcp application's window, I need to set label text dynamically after the creation of the window.</p>
  
  <p>When the window is created I would have created the label control but I would not set the text by then. After user selects a button on the window, I want to set the text of the label inside the button's selection listener method. After setting text to label inside button's selection listener method I am not able to see the text on the window.</p>
  
  <p>Why is that I am not able to see the label text on the window when I set it inside the listener method? Is it because the window is already created?</p>
  
  <p>how do I solve this? </p>
