Re: Clist

[Brad House <brad mainstreetsoftworks com>]

Well, I finally figured out how to get a selection from a CLIST...but
VERY undocumented!!!  Pulled this info directly out of the source...
It works fantasically...so for anyone else that may need this looking
through the archives, I post this.

int CList_get_selected(GtkCList *clist, int **listings)
{
  GList *list;
  int cnt=0;

  if (clist==NULL) return(0);

  list=clist->selection;
  listings[0]=NULL;
  while(list)
  {
    listings[0]=(int *)realloc(listings[0], (cnt+1)*sizeof(int));
    listings[0][cnt]=GPOINTER_TO_INT(list->data);
    list=list->next;
    cnt++;
  }
  return(cnt);
}

anyhow, it returns the number of rows selected.  Obviously
for a single CList it will return 1 assuming a row is selected.
you should call it like this:

int cnt, i, *listings=NULL;
GtkWidget *w;  /* direct to widget of your clist */
cnt=CList_get_selected(GTK_CLIST(w), &listings);
for (i=0; i<cnt; i++) {
   /* do something with listings[i] */
}
free(listings);

I really wish this function which I just defined existed
in GTK...it's a hell of a lot easier than grabbing
clicking events and storing what selection was clicked,
etc....

Oh well, apparently you shouldn't even use CLists in v2.0

hmm...
