The dialog is not necessarily modal, if you want modal behaviour add
"GTK_DIALOG_MODAL" to the dialog flags.

When using gtk_dialog_run () a recursive mainloop gets started and
(some) event processing for the parent windows widgets get blocked.
Unless you want some custom behaviour it then usually is not necessary
to connect to the respond-signal (which *is* probably needed if you want
multiple dialogs simultaneously).

You also can force the dialog to respond by calling
gtk_dialog_response(). This is useful if you e.g. want to cancel a
dialog because of external conditions.

Bye,
