Right -- I didn't catch they were bit flags.
(I thought they were unique values, because of the 1,2,3..)
I rewrote it this way now; let me know if it's still unclear:
/** Anonymous enum bit flags for has_scrollbar().
- bit 0: horizontal
- bit 1: vertical
- bit 2: 'always' (to be combined with bits 0 and 1)
- bit 3-31: reserved for future use
*/
enum { // values for has_scrollbar()
HORIZONTAL = 1, ///< Only show horizontal scrollbar.
VERTICAL = 2, ///< Only show vertical scrollbar.
BOTH = 3, ///< Show both scrollbars. (default)
ALWAYS_ON = 4, ///< Specified scrollbar(s) should 'always' be
shown (to be used with HORIZONTAL/VERTICAL)
HORIZONTAL_ALWAYS = 5, ///< Horizontal scrollbar always on.
VERTICAL_ALWAYS = 6, ///< Vertical scrollbar always on.
BOTH_ALWAYS = 7 ///< Both scrollbars always on.
};
