title: How to disable almost all components in a JFrame?
body: <p>When I start some processing, I want to disable the JButtons, JText, Lists, etc. in the GUI, only having one button to stop the processing.</p>
  
  <p>What is a clean way to do this? I was setting component by component with setEnabled(false), but the code was too big.</p>
  
  <p>Can I get all the components in an array and set all inside a for loop? How I do this? There is another way?</p>
