Change item resources
PtTreeItem_t *PtTreeModifyItem( PtWidget_t *tree, PtTreeItem_t *item, const char *string, short set_img, short unset_img );
This function changes item resources:
- The item's string is changed to be a copy of string. If string is NULL, the item's string isn't changed.
- The set_img argument is the index of the image that's displayed when the item is set, and unset_img is the image displayed when it isn't set. An item is considered set if its flags masked with the Pt_ARG_TREE_IMGMASK resource of the widget give a nonzero value.
The tree is a pointer to the PtTree that the item belongs to, or NULL. If the item is in a tree, it must be in the one pointed to by tree.
The new address of the item.
|This address may differ from the old one if the new string is longer.|
