RE: RV: Avoiding multiple child-windows

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

Is there any reason why you couldn't do something slightly different by
retrieving the gdkwindow of the widget after it's been created like this;

> void create_param_window(GtkWidget *widget)
{
	/* Declaring local variables */
	static GdkWindow *window = (GdkWindow *) NULL;

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

	/* Creating new window */
	ParamWindow *NewParamWindow = new_ParamWindow(widget);
	window = GTK_WIDGET(widget)->window;
	gtk_widget_show(NewParamWindow->GetWidget());
}
