issues about modal dialogs

[Johnny Mnemonic <johnny themnemonic org>]

Greetings

I have some troubles with the modal dialogs. Well, to sum up the thing, i'll 
list the points:

- How can I make modal dialogs "always-on-top" between my application 
windows? Just like Win32's modals, that won't allow hiding the dialog 
under another window of the same application.
- I want the modal dialog to return in the same place where i called it from, 
calling a nested gtk_main(). In order to do this, I know that i have to 
handle several situations.. What should I handle other than window destroy, 
buttons clicks, and window delete?
- Is there anything else i need to know to get the nested gtk_main() working 
safely? Also if you know some applications example please let me know.

Thank you for your time
