Hi all!

    I've built a very simple C program to draw some things in a window
using GDK. The question is that, although the window is displayed OK,
the rectangle I try to draw inside does not appear. What I'm doing
wrong? I send you the program. Please, enlightment me some!! The only
I want is to draw a red rectangle somewhere in the window, but I don't
know how...

    Regards and thanks in advance.
    diego.

#include <gdk/gdk.h>

int
main (int argc, char *argv[])
{
        GdkWindow* win;
        GdkWindowAttr attr;
        GdkEvent* e;
        GdkGCValues dcval;
        GdkGC* gc;
        GdkColormap* colormap;

        int i;

        /* Initialize GDK. */
        gdk_init (&argc, &argv);

        /* Initialize window attributes */
        attr.x = attr.y = 0;
        attr.height = attr.width = 200;
        attr.wclass = GDK_INPUT_OUTPUT;
        attr.window_type = GDK_WINDOW_TOPLEVEL;
        win = gdk_window_new(NULL,&attr,0);

        /* Initialize GdkGCAttributes */
        dcval.foreground.red = 65535;
        dcval.foreground.green = 0;
        dcval.foreground.blue = 0;
        dcval.background = dcval.foreground;

        colormap = gdk_window_get_colormap ( win );
        if (gdk_colormap_alloc_color(colormap, &dcval.foreground,
FALSE,TRUE))
                printf( " OK color \n");

        gc = gdk_gc_new_with_values ( win, &dcval,
                                      GDK_GC_BACKGROUND |
GDK_GC_FOREGROUND);

        /* Draw a rectangle */
        gdk_draw_rectangle ( win , gc,  1, 10,10,100,100);

        /* Show window */
        gdk_window_show(win);

        while (1)
        {
                if (gdk_events_pending() && (e = gdk_event_get())) {
                        printf("[Event: %d]\n", e->type);
                }
        }

        scanf("%d",&i);

        /* Exit from GDK...this call will never return. */
        gdk_exit (0);

        /* Keep compiler from issuing a warning */
        return 0;
}
