Question

I have been trying to implement Win32\'s MessageBox using GTK. The app uses SDL/OpenGL, so this isn\'t a GTK app.

To manage a dialog box with GTK+, use a GtkDialog and gtk_dialog_run() instead of managing a window and a main loop by yourself.

EDIT / ADDENDUM :

What I mean is "just use" : I don't understand why you create a windows you never use and a main loop which seems useless (at least from the piece of code you posted). You can write something as short as :

int MessageBox(HWND hwnd, const char* text, const char* caption, UINT type)
{
    GtkWidget *dialog ;

    /* Instead of 0, use GTK_DIALOG_MODAL to get a modal dialog box */

    if (type & MB_YESNO)
        dialog = gtk_message_dialog_new(NULL, 0, GTK_MESSAGE_QUESTION, GTK_BUTTONS_YES_NO, text );
    else
        dialog = gtk_message_dialog_new(NULL, 0, GTK_MESSAGE_INFO, GTK_BUTTONS_OK, text );


    gtk_window_set_title(GTK_WINDOW(dialog), caption);
    gint result = gtk_dialog_run(GTK_DIALOG(dialog));
    gtk_widget_destroy( GTK_WIDGET(dialog) );

    if (type & MB_YESNO)
    {
        switch (result)
        {
        default:
        case GTK_RESPONSE_DELETE_EVENT:
        case GTK_RESPONSE_NO:
            return IDNO;
        case GTK_RESPONSE_YES:
            return IDYES;
        }
        return IDOK;
    } 
}
