Non-blocking dialog




Hello there!

I'm writing a GTK+ application in C. In my application I'm running two commands that take a bit of time; in order to not make it appear that the program has just frozen, I am wanting to do the following:

1) run the dialog, which has a spinner widget
2) add to the dialog area a message that says what the first command does
3) run the first command
4) add a message saying that the second command is running
5) run the second command
6) add a done message
7) allow the user to click "Ok" to close (or maybe delay for a second and close)

Additionally, I am creating this dialog within a callback (as it is supposed to appear when the user clicks the "Next" button in the main application).
 
However, my problem is that the dialog only appears after everything has been executed and the callback finishes execution. Here's what I'm running:

{
...
    diag = create_progress_spinner_dialog(window, &box); 
    /*gtk_widget_set_can_focus(diag, TRUE);*/
    /*gtk_window_set_modal(GTK_WINDOW(diag), TRUE);*/
    /*gtk_window_set_transient_for(GTK_WINDOW(diag), GTK_WINDOW(window));*/
    /*gtk_widget_show_all(diag);*/

    gtk_box_pack_start(GTK_BOX(box), gtk_label_new("Formatting..."), TRUE, TRUE, 10);
    gtk_widget_show_all(diag);
    format_target_device(info->target_device, fs_choice);

    gtk_box_pack_start(GTK_BOX(box), gtk_label_new("Mounting..."), TRUE, TRUE, 10);
    gtk_widget_show_all(diag);
    mount_target_device(info->target_device);

    gtk_box_pack_start(GTK_BOX(box), gtk_label_new("Done!"), TRUE, TRUE, 20);
    gtk_widget_show_all(diag);

    gtk_notebook_next_page(GTK_NOTEBOOK(globals->notebook));

    push_stack(globals->pages, 1);
    set_next_hb_title(globals);
}

As you can see by the comments, I tried quite a few things with no success. However, if I put the gtk_dialog_run in there and it will appear but it obviously blocks execution which isn't helpful to me. I'm really not sure where to go from here; any help would be greatly appreciated.

Thanks!
