Hi,

I have several text fields on a dialog that I have to ensure are all filled in. I would like to check them all in the 
Done callback (when they click on a Done button). I will display a message informing them of what needs correcting.

I don't see how you can keep the dialog from closing, though. I see an example of preventing someone from closing via 
the menu or 'x' button (and if they do want to close - it exits the application - not just the dialog).

So, can someone help with this?

Thanks,

Frank
