Create a tree item with attributes
PtTreeItem_t *PtTreeChangeItem(
PtWidget_t *tree,
PtTreeItem_t *item,
const char *string,
PtTreeItemAttributes_t const *attr
);
- tree
- A pointer to the PtTree widget which contains
the item you want to change.
- item
- A pointer to the PtTreeItem_t you wish to
change.
- string
- The tree item text string. Set to NULL to
leave the item's text string unchanged.
- attr
- A pointer to the new PtTreeItemAttributes_t structure
you want to set for this item. Set to NULL to display
no images, and use the widget-defined font and colors. The Pt_TREE_ITEM_HAS_ATTRS flag
bit is still set for the item.
This function changes an existing tree item, created with PtTreeCreateItem() or
PtTreeAllocItem().
The string and attr parameters will override
the existing item text string and attributes.
- A pointer to a PtTreeItem_t
- Success.
- NULL
- Error
See “Allocating
items and building a tree” in the description of PtTree.
