-    wx.DD_NEW_DIR_BUTTON  Add 'Create new directory' button and allow
-                          directory names to be editable. On Windows
-                          the new directory button is only available
-                          with recent versions of the common dialogs.
+    wx.DD_DIR_MUST_EXIST  The dialog will allow the user to choose only an
+                          existing folder. When this style is not given, a
+                          'Create new directory' button is added to the dialog
+                          (on Windows) or some other way is provided to the

+                          Use this instead of deprecated wx.DD_NEW_DIR_BUTTON.
 
     wx.DD_CHANGE_DIR      Change the current working directory to the
                           directory chosen by the user.
