title: How can I make sure the content of a tkinter entry is saved on FocusOut?
body: <p>I have an app that uses <code>&lt;FocusOut&gt;</code> binding to automatically save the edits in an <code>Entry</code> to a list.</p>
  
  <p>There is no problem saving the <code>Entry</code> text when using <code>TAB</code> to navigate through the Entries or when I click on another Entry, but If I change the text on one Entry and then if I mouse-click on a <code>ListBox</code> in another frame, <code>&lt;FocusOut&gt;</code> doesn't work on the last selected Entry and the information in it is not registered. </p>
  
  <p>How can I avoid this without resorting to a <code>Save</code> button on the GUI? For every selection in the <code>ListBox</code> there are different <code>Entry</code> boxes, so the user would have to press the <code>Save</code> button numerous times. I would like to avoid that.</p>
