Detailed Description

A Tree List Widget organizes items in a hierarchical, tree-like fashion.

Subtrees can be collapsed or expanded by double-clicking on an item or by clicking on the optional plus button in front of the item. Each item may have a text and optional open-icon as well as a closed-icon. The items may be connected by optional lines to show the hierarchical relationship. When an item's selected state changes, the treelist emits a SEL_SELECTED or SEL_DESELECTED message. If an item is opened or closed, a message of type SEL_OPENED or SEL_CLOSED is sent. When the subtree under an item is expanded, a SEL_EXPANDED or SEL_COLLAPSED message is issued. A change of the current item is signified by the SEL_CHANGED message. In addition, the tree list sends SEL_COMMAND messages when the user clicks on an item, and SEL_CLICKED, SEL_DOUBLECLICKED, and SEL_TRIPLECLICKED when the user clicks once, twice, or thrice, respectively. When items are added or removed, the tree list sends messages of the type SEL_INSERTED or SEL_DELETED. In each of these cases, a pointer to the item, if any, is passed in the 3rd argument of the message.
