I think we should warn the user with a dialog that the resulting layout will definitely be invalid in CEGUI's eyes. We should just write an empty file if user chooses to proceed (not using compatibility layers at all).

Setting this to general category since it probably applies to all editors, not just layout. New file is always <= 2 bytes long and using compat layers on that is likely to fail.

14:48 < CrazyEddie> how about "You can not save a layout without a root
                    element, a DefaultWindow root will now be created": "OK" /

Probably more pragmatic, I am inclined to do this instead of just a warning. A good rule would be to never allow invalid data to be created with the editor.

I haven't looked at this part of the code but shouldn't an empty layout file have the following (at least)?

<?xml version="1.0" ?>
<GUILayout version="4">

This doesn't solve the issue but I think it's related.

Last, the prompt dialog should have a Cancel button and a "Create DefaultWindow" (or "Create root" or "Create") button, not just "OK". See mainwindow.py, slot_newFileDialog()

pav: You are right but CEED doesn't recognize that as "empty" layout. So in the end I will have to go with "". Trying to load your layout results in CEGUI bitching about it ;-) It's an invalid layout still...

In the end I just pop a dialog saying that CEED won't save and user should add a root widget. Adding the option to add a root widget automatically is IMO not worth it (time investment vs benefit).

Fixed with b316106b50b0
