GdkGC Question

[Ajit Krishnan <akrishna julian uwo ca>]

hi,

I'm having a couple of problems with gdk and i wonder if one of you
could help me :-)

I'm double buffering my screen output onto a pixmap first which i've
defined as a GdkDrawable *pixmap and then i have two functions exposeEvent
and configureEvent (just like in the tutorials). the configureEvent draws
onto the pixmap and the exposeEvent draws the pixmap onto the screen.

i'm having a problem with the graphics contexts (i.e. don't really understand
them) i have the pixmap, and would like the background to be grey and the
foreground writing to be black.....so this is what i tried...

here is the important excerpt from 

w_configureEvent (GtkWidget *widget, GtkEventConfigure *event) {

GdkColormap *cmap = gdk_colormap_get_system ();
Gdkcolor cblack, cgrey;
GdkGC *gc;

cblack.red = 0; 
cblack.green = 0;
cblack.blue = 0;

cgrey.red = 0x9000;
cgrey.green = 0x9000;
cgrey.blue = 0x9000;

if (!gdk_color_alloc (cmap, &cgrey)) g_warning ("problem with red");
if (!gdk_color_alloc (cmap, &cblack)) g_warning ("problem with black");

if (pixmap) gdk_pixmap_unref (pixmap);

pixmap = gdk_pixmap_new (widget->window, widget->allocation.width, widget->allocation.height, -1);

gc = gdk_gc_new (pixmap);
gdk_gc_set_background (gc, &grey);
gdk_gc_set_foreground (gc, &black);
gdk_draw_rectangle (info->amsa_pixmap, gc, TRUE, 0, 0, 300, 300);


.
.
.

Now, i'd expect that i should get a rectangle with a black border and a grey fill colour.
instead i get a solid black rectangle....the funny thing is i get a solid black rectangle
even if i change the background and foreground colours of gc to white...

can someone please tell me what i'm doing wrong?

thanks,
ajit
