Add items in front of any existing items
int PtGenTreeAddFirst( PtWidget_t *tree,
PtGenTreeItem_t *item,
PtGenTreeItem_t *parent );
This function adds the list of PtGenTreeItem_t structures
pointed to by item to the given PtGenTree widget.
The list of items are linked with their brother fields.
The item argument can be NULL.
The parent argument identifies the parent item for
the added items (if any).
The new items are added in front of any existing
children of the parent item.
If parent is NULL, the items are added at the root
level of the tree, before any existing items there.
The tree argument can be NULL,
provided that parent points to an item that isn't attached to
any tree widget.
PtGenTreeAddFirst() sets the
Pt_TREE_ITEM_EXPANDABLE flag in the parent
item, whether or not the item argument is NULL.
- 0
- Success.
- -1
- The item is already in a widget.
