Subject: Fix wxALWAYS_SHOW_SB behaviour in wxGTK.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/d8ba3099e1b077a34aedbf8efaeb4cf9d85924a6

Fix wxALWAYS_SHOW_SB behaviour in wxGTK.

Don't show the scrollbar always if it's not enabled at all, i.e. if the
corresponding wxHSCROLL or wxVSCROLL style is not specified.
