(14) SelFgColor is 0 (use Windows default).

(15) SelNoFocusBgColor is 0 (use Windows default).

If the user changes the style to TVF_CLASSIC, all of the above settings will be applied.

Specifies that this TreeviewField exhibits different behavior from TreeviewFields with the TVF_CLASSIC style. It has no attributes that are automatically set; they are all user-settable. It is the default style for newly created treeviewfields. Newly created treeviewfields also take on different defaults for:

(1)  RightClickBehavior (see RightClickBehavior Attribute)—RB_SELECT
(2)  HasHorizontalScrollbar (see HasHorizontalScrollBar Attribute)—FALSE

If the user changes any of the 16 listed attributes of style TVF_CLASSIC in the Property Inspector, then the style is automatically converted to TVF_EXTENDED, although no other values are modified unless explicitly done so by the user.

Is identical to TVF_EXTENDED in the current release of OpenROAD. The difference between the styles is that if future releases create a new style, TVF_CURRENT will automatically be updated to the latest style, whereas TVF_EXTENDED will not.
