problem setting the background color of a widget

[Ronald Bultje <rbultje tux bitfreak net>]

Hey people,

here's a Really Stupid Question (tm).

If I make something like a event-box, how do I set the backgroundcolor
to, for example, black?
I tried the following code:

GdkColor *color;
GdkGC *gc;
GtkWidget *widget;

widget = gtk_event_box_new();
gtk_widget_set_usize(GTK_WIDGET(widget), width, height);
/* the vbox2 is already there */
gtk_box_pack_start (GTK_BOX (vbox2), widget, FALSE, FALSE, 0);
gtk_widget_show(widget);
gc = gdk_gc_new(window->window);
color = (GdkColor *)malloc(sizeof(GdkColor));
color->red = 0;
color->green = 0;
color->blue = 0;
color->pixel = (gulong)(0);
gdk_color_alloc(gtk_widget_get_colormap(window), color);
gdk_gc_set_foreground(gc, color); (I also tried gdk_gc_set_background)
/*gdk_draw_rectangle(lavedit_tv->window, gc, 1, 0, 0, tv_width_edit,
tv_height_edit);*/
gdk_gc_destroy(gc);


If I uncomment the gdk_draw_rectangle, it will segfault (probably
because one of the parents has not been realized yet).
But gtk_widget_realize() was a really bad idea, If I remember correctly.
So..... what am I doing wrong, not understanding correctly or is there a
much better way to do this?

Thanks in advance,

Ronald
