CList scrollbar setting solution!

["D. Emilio Grimaldo Tunon" <emilio_tunon nl compuware com>]

Please disregard my previous message (didn't get any responses
anyway...) I found out how to do it in 1.0.5 if anybody is
interested I will post it here. It looks ugly (and is ugly
and heavily relies upon knowledge of the internal structures!)
but it works:


typedef struct {
    GtkAdjustment *adjustment;
    gfloat	   value;
} ClistScrollStruct;

ClistScrollStruct cscroll;

gfloat getClistScrollbarValue(gint vertical, GtkAdjustment **adj)
{
    GtkWidget *vsw;
    GtkScrollbar vs;
    GtkRange   vsr;
    GtkAdjustment *adjPtr;
    gfloat  	   value;

    if (vertical) {
	vsw = GTK_CLIST(clist)->vscrollbar;
    } else {
	vsw = GTK_CLIST(clist)->hscrollbar;
    }

    vs = GTK_VSCROLLBAR(vsw)->scrollbar;
    vsr = vs.range;
    adjPtr = gtk_range_get_adjustment(&vsr);
    value = adjPtr->value;
    *adj = adjPtr;
    return(value);
}

/* Some point just before using clist_clear() save the
 * current position of the scrollbar
 */
 cscroll.value = getClistScrollbarValue(1, &cscroll.adjustment);
 gtk_clist_clear();

/* Then the clist is populated again. And for the sake of the
 * hack let's assume the previous setting is still within
 * bounds.
 */
 <populate clist>
 
 /*
  * At this point the vscrollbar is at the top, lets position
  * it to our last known setting that we saved.
  */
 gtk_adjustment_set_value(cscroll.adjustment, cscroll.value);


I will clean this up and use it in my 1.0.5 application (this
was just an experiment so coding is not perfect!. But I would
definitely like to know:

   1. Is there a simpler way to do it in 1.0.5?
   2. What about less internals-dependent way? (1.0.5)
   3. How to do it in 1.1.x (I don't have that)

		Thanks,
