     Auto-remove is on by default.

+    responsibility on to another process. Always use the fileName() function to
+    obtain the name and never try to guess the name that QTemporaryFile has

+    On some systems, if fileName() is not called before closing the file, the
+    temporary file may be removed regardless of the state of this property.
+    This behavior should not be relied upon, so application code should either
+    call fileName() or leave the auto removal functionality enabled.
