Creates a new GtkDialog with title @title (or %NULL for the default title; see gtk_window_set_title()) and transient parent @parent (or %NULL for none; see gtk_window_set_transient_for()). The @flags argument can be used to make the dialog modal (GTK_DIALOG_MODAL) and/or to have it destroyed along with its transient parent (GTK_DIALOG_DESTROY_WITH_PARENT). After @flags, button text/response ID pairs should be listed, with a %NULL pointer ending the list. Button text can be either a stock ID such as GTK_STOCK_OK, or some arbitrary text. A response ID can be any positive number, or one of the values in the GtkResponseType enumeration. If the user clicks one of these dialog buttons, GtkDialog will emit the GtkDialog::response signal with the corresponding response ID. If a GtkDialog receives the GtkWidget::delete-event signal, it will emit ::response with a response ID of GTK_RESPONSE_DELETE_EVENT. However, destroying a dialog does not emit the ::response signal; so be careful relying on ::response when using the GTK_DIALOG_DESTROY_WITH_PARENT flag. Buttons are from left to right, so the first button in the list will be the leftmost button in the dialog. Here's a simple example: |[ GtkWidget *dialog = gtk_dialog_new_with_buttons ("My dialog", main_app_window, GTK_DIALOG_MODAL | GTK_DIALOG_DESTROY_WITH_PARENT, GTK_STOCK_OK, GTK_RESPONSE_ACCEPT, GTK_STOCK_CANCEL, GTK_RESPONSE_REJECT, NULL); ]|
