Subject: Handle successive key presses better in wxGenericTreeCtrl search code.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/4d1cf9f3d3d6fc1dc8b29fe16a08b4c9b0545368

Handle successive key presses better in wxGenericTreeCtrl search code.

Go to the next item starting with the given character if the same one is
pressed multiple times. This is more useful than searching for an item
starting with multiple occurrences of this character (which usually won't
exist) and is more consistent with how Windows handles this.
