00223 * A Tree List Widget organizes items in a hierarchical, tree-like fashion.
00224 * Subtrees can be collapsed or expanded by double-clicking on an item
00225 * or by clicking on the optional plus button in front of the item.
00226 * Each item may have a text and optional open-icon as well as a closed-icon.
00227 * The items may be connected by optional lines to show the hierarchical
00228 * relationship.
00229 * When an item's selected state changes, the treelist emits a SEL_SELECTED
00230 * or SEL_DESELECTED message.  If an item is opened or closed, a message
00231 * of type SEL_OPENED or SEL_CLOSED is sent.  When the subtree under an
00232 * item is expanded, a SEL_EXPANDED or SEL_COLLAPSED message is issued.
00233 * A change of the current item is signified by the SEL_CHANGED message.
00234 * In addition, the tree list sends SEL_COMMAND messages when the user
00235 * clicks on an item, and SEL_CLICKED, SEL_DOUBLECLICKED, and SEL_TRIPLECLICKED
00236 * when the user clicks once, twice, or thrice, respectively.
00237 * When items are added or removed, the tree list sends messages of the
00238 * type SEL_INSERTED or SEL_DELETED.
00239 * In each of these cases, a pointer to the item, if any, is passed in the
00240 * 3rd argument of the message.
