pz_widget_set_timer

I finally got podzilla building, and now I've ran into yet another problem.
I'm probably missing something but pz_widget_set_timer() doesn't seem to work..

Here's some of my functions:

Code:

//Init window function
PzWindow *new_ifsg_window()
{
    g_moving_y = 25;

    window = pz_new_window ("FSG", PZ_WINDOW_FULLSCREEN);
    pz_widget_set_timer(pz_add_widget (window, draw_ifsg, event_ifsg), 100);
    return pz_finish_window (window);
}

//Draw window function
void draw_ifsg (PzWidget *wid, ttk_surface srf)
{
    ttk_fillrect (srf, 0, 20, ttk_screen->w, ttk_screen->h, ttk_makecol(BLACK));

    /*
    #define MSG "Press a button to quit."
    ttk_text (srf, ttk_menufont, wid->x + (wid->w - ttk_text_width (ttk_menufont, MSG)) / 2,
         wid->y + wid->h - ttk_text_height (ttk_menufont) - 5, ttk_makecol (WHITE), MSG);
    */

    ttk_line (srf, wid->x + 5, g_moving_y, wid->x + 5, g_moving_y, ttk_makecol (0, 255, 0));
    
    g_moving_y ++;
}

Is this supposed to make draw_ifsg loop once a second?

All events aside from the draw event are delegated to the event function you specify in pz_add_widget. To request a redraw, simply set the PzWidget's dirty member to some non-zero value. For example:

Code:

static int g_moving_y;

int event_ifsg (PzEvent *ev)
{
    int ret = 0;
    switch(ev->type) {
        case PZ_EVENT_TIMER:
            g_moving_y++;
            /* mark widget as dirty to instigate a redraw */
            ev->wid->dirty = 1;
            break;

        /* other handlers go here */
        default:
            ret |= TTK_EV_UNUSED;
    }
    return ret;
}

void draw_ifsg (PzWidget *wid, ttk_surface srf)
{
    ttk_fillrect (srf, 0, 20, ttk_screen->w, ttk_screen->h, ttk_makecol(BLACK));

    /*
    #define MSG "Press a button to quit."
    ttk_text (srf, ttk_menufont, wid->x + (wid->w - ttk_text_width (ttk_menufont, MSG)) / 2,
         wid->y + wid->h - ttk_text_height (ttk_menufont) - 5, ttk_makecol (WHITE), MSG);
    */

    ttk_line (srf, wid->x + 5, g_moving_y, wid->x + 5, g_moving_y, ttk_makecol (0, 255, 0));
}

PzWindow *new_ifsg_window()
{
    g_moving_y = 25;

    window = pz_new_window ("FSG", PZ_WINDOW_FULLSCREEN);
    pz_widget_set_timer(pz_add_widget (window, &draw_ifsg, &event_ifsg), 100);
    return pz_finish_window (window);
}

Oh ok, that makes sense.
