+ @style{wxHSCROLL}
+ If this style is specified and ::wxVSCROLL isn't, the window will be
+ scrollable only in horizontal direction (by default, i.e. if neither
+ this style nor ::wxVSCROLL is specified, it scrolls in both
+ directions).
+ @style{wxVSCROLL}
+ If this style is specified and ::wxHSCROLL isn't, the window will be
+ scrollable only in vertical direction (by default, i.e. if neither
+ this style nor ::wxHSCROLL is specified, it scrolls in both
+ directions).
+ @style{wxALWAYS_SHOW_SB}
+ Since wxWidgets 2.9.5, specifying this style makes the window always
+ show its scrollbars, even if they are not used. See ShowScrollbars().
