Method

GtkDialogrun

Declaration [src]

gint
gtk_dialog_run (
  GtkDialog* dialog
)

Description [src]

Blocks in a recursive main loop until the dialog either emits the GtkDialog::response signal, or is destroyed. If the dialog is destroyed during the call to gtk_dialog_run(), gtk_dialog_run() returns

GTK_RESPONSE_NONE. Otherwise, it returns the response ID from the

::response signal emission.

Before entering the recursive main loop, gtk_dialog_run() calls gtk_widget_show() on the dialog for you. Note that you still need to show any children of the dialog yourself.

During gtk_dialog_run(), the default behavior of GtkWidget::delete-event is disabled; if the dialog receives ::delete_event, it will not be destroyed as windows usually are, and gtk_dialog_run() will return

GTK_RESPONSE_DELETE_EVENT. Also, during gtk_dialog_run() the dialog

will be modal. You can force gtk_dialog_run() to return at any time by calling gtk_dialog_response() to emit the ::response signal. Destroying the dialog during gtk_dialog_run() is a very bad idea, because your post-run code won’t know whether the dialog was destroyed or not.

After gtk_dialog_run() returns, you are responsible for hiding or destroying the dialog if you wish to do so.

Typical usage of this function might be:

  GtkWidget *dialog = gtk_dialog_new ();
  // Set up dialog...

  int result = gtk_dialog_run (GTK_DIALOG (dialog));
  switch (result)
    {
      case GTK_RESPONSE_ACCEPT:
         // do_application_specific_something ();
         break;
      default:
         // do_nothing_since_dialog_was_cancelled ();
         break;
    }
  gtk_widget_destroy (dialog);

Note that even though the recursive main loop gives the effect of a modal dialog (it prevents the user from interacting with other windows in the same window group while the dialog is run), callbacks such as timeouts, IO channel watches, DND drops, etc, will be triggered during a gtk_dialog_run() call.

Return value

Returns: int
 

Response ID.
