+        get_value_as_int() does not return the most up-to-date value if the user is
+        in the middle of editing the value in a spinbutton. Instead, it actually
+        returns the value previously "confirmed" for the spinbutton (for example,
+        by moving focus to another widget).
+        
+        Example: User starts with all spinboxes set to 0. He types 5 in 'Minutes' and
+        immediately uses the keyboard to activate the 'Save as Preset' button. Because
+        the user never moved focus out of the spinbutton, get_value_as_int() will report
+        the previous value of 0, and the saved preset will not have the expected duration
+        of 5 minutes.
+        
+        If a particular spinbutton is empty or contains a non-float value, then this method
+        will report its value as zero.
