RE: Avoiding multiple child-windows

["Dugas, Alan" <alan dugas analog com>]

You could try something like this;

/* Declaring local variables */
static GtkWidget *window = NULL;
...

/* Return if window already exists */
if ( window )
{
	gdk_window_raise(GTK_WIDGET(window)->window);
	return;
}

/* Creating window */
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
...

[Note: make sure you set window == NULL in your destroy callback for the window,
otherwise you will not be able to create the window again if the user destroys
it!]

Hope this helps.
