3-D Adds 3-D decoration around the border of the control. Effective only on boxed Tree-Views. (create, modify)
BOXED Indicates that a box should be placed around a tree-view. This is the default. (create)
BUTTONS Places small buttons to the left of each item that the user can click to expand or collapse the item in addition to double-clicking the item. The buttons show a "+" if the item can be expanded, or a "-" if it can be collapsed. Items with no subsidiary items do not get a button. Also, buttons are placed on the top level items only if you also specify the SHOW-LINES and LINES-AT-ROOT styles. (Note: some versions of Windows are known to have a bug that prevents the buttons from displaying correctly if you do not also specify the SHOW-LINES style.) (create, modify)
LINES-AT-ROOT Allows the SHOW-LINES and BUTTONS styles to apply to top level items. (create, modify)
NO-BOX This style removes the box that normally displays around the control. (create)
SHOW-LINES Causes faint lines to be drawn between the items to help clarify their nesting relationship. Lines are not drawn between top level items unless you also specify the LINES-AT-ROOT style. (create, modify)
SHOW-SEL-ALWAYS When this style is applied, the control always shows the current selection, even when it does not have the focus. The default is to hide the selection when the control does not have the focus. (create, modify)
