Verifying input data before gtk_dialog_run returns
Hi, Is there a recommended way to check if the data in a dialog is valid when the user presses the OK button? If the data is not OK I want to present a modal dialog saying there is an error. If the user closes that dialog the user can correct the error and press OK again. The concrete case I'm looking at is in a file save dialog where I want to check if a user entered a valid file extension when he/she presses the save button.

You can read the values, otherwise you would not be able to
use the dialog at all.
The dialog does not close itself on OK, you always
explicitly destroy it.
So you can read the values and *not* destroy the dialog if
you don't like them (and display another dialog, etc.),
right? See also the recusrive dialogs in my last post
(http://mail.gnome.org/archives/gtk-app-devel-list/2007-March/msg00154.html).
So the recommended way to do it is just do the following (in pseudo code)
do {
response = gtk_dialog_run ()
} while (response == OK !validated )
I thought of using this but it did not really seem like an elegant way
to do it. I was thinking that there might be some signal handler which
could do the checking and that gtk_dialog_run would only return if OK
was pressed and the data was valid
