13.3.3 Replacing Items

There are also a number of functions for replacing items in a List. To replace a contiguous sequence of items, use

either XmListReplaceItemsPos() or XmListReplaceItemsPosUnselected(). These functions take

the following form:

void

XmListReplaceItemsPos(list_w, new_items, item_count, position)

Widget list_w;

XmString *new_items;

int item_count;

int position;

void

XmListReplaceItemsPosUnselected(list_w, new_items, item_count,

position)

Widget list_w;

XmString *new_items;

int item_count;

int position;

These functions replace the specified number of items with the new items starting at position. The difference

between the two functions is the same as the difference between the List routines that add items selected and

unselected. XmListReplaceItemsPosUnselected() is a new routine in Motif 1.2.

You can also replace arbitrary elements in the list with new elements, using XmListReplaceItems() or

XmListReplaceItemsUnselected. These routines take the following form:

void

XmListReplaceItems(list_w, old_items, item_count, new_items)

Widget list_w;

XmString *old_items;

int item_count;

XmString *new_items;

void

XmListReplaceItemsUnselected(list_w, old_items, item_count, new_items)

Widget list_w;

XmString *old_items;

int item_count;

XmString *new_items;

These functions work by searching the entire list for each element in old_items ...
