how do i set the tooltip color?

[David Benson <daveb idealab com>]

I cannot seem to set the tooltip color, and I don't know why...

Here is my test program, which doesn't print any errors,
but also has a tooltip w/ default colors...


===== CUT
#include <gtk/gtkbutton.h>
#include <gtk/gtkmain.h>
#include <gtk/gtkwindow.h>
#include <gtk/gtktooltips.h>

int main(int argc, char** argv)
{
	GtkWidget* widget;
	GtkWidget* window;
	GtkTooltips* tooltips;
	gboolean succeeded;
	GdkColor colors[2];

	gtk_init(&argc, &argv);

	colors[0].red    = 65535;		/* red and green */
	colors[0].green  = 0;
	colors[0].blue   = 0;
	colors[1].red    = 0;
	colors[1].green  = 65535;
	colors[1].blue   = 0;
	gdk_colormap_alloc_colors(gdk_colormap_get_system(),
	                          colors,
				  2,
				  FALSE,
				  TRUE,
				  &succeeded);
	g_return_val_if_fail(succeeded, 1);

	widget = gtk_button_new_with_label("hello");
	tooltips = gtk_tooltips_new();
	gtk_tooltips_set_colors(tooltips, colors + 0, colors + 1);
	gtk_tooltips_set_tip(tooltips, widget, "what?", "huh?");

	gtk_widget_show(widget);

	window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
	gtk_container_add(GTK_CONTAINER(window), widget);
	gtk_widget_show(window);
	
	gtk_main();

	return 0;
