How to use GdkColor?

[erwin verhulst philips com]

Hi

I've attached a simple program that draws a rectangle when you click with the mouse in the window. It worked fine until I wanted to chance the color of the rectangle. The program compiles OK, but when I try to run it the following message appears.

* ERROR * sigsegv caught

What is wrong with the program?

Can somebody get me on track?

Thanks,

P.S. I've got this program from the GTK-list. I've lost the GOOD man's name, but who ever it was, THANKS A MILLION.

#include <glib.h>

GtkWidget *drawingarea = NULL;

	gtk_main_quit ();
	}

	GdkColor *color1;
	color1->red = 65;
	color1->green = 0;
	color1->blue = 0;
	gdk_gc_set_foreground (widget->style->fg_gc[1], color1);

	 /* Check if we've received a button pressed event */
	if (event->type == GDK_BUTTON_PRESS )
