title: Delete icon from MDI container form
body: <p><img src="https://i.stack.imgur.com/pCJSW.jpg" alt="enter image description here"></p>
  
  <p>I have a parent form and some child forms. Each of the child form has an icon at the top and left of the form. I would like to discard those icons but when I click on the icon property, I can only browse another icon and not delete the existing one. For that reason I set the showIcon property in each child form to false and the icons are not visible any more on the forms. So far so good.</p>
  
  <p>My problem is that when a child form is open and maximized, the icon is shown. I want to make it go away and unfortunately I didn't find a way to do this. Any suggestions?</p>
  
  <p>Thanks!</p>
  
  <p>EDIT: I added a screenshot of the form, the unwanted icon is shown above menu strip. I want it to go away. When child form is NOT maximized, the icon disappears.</p>
