Subject: linking commands on the individual window level, otherwise built-in handlers override... 
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/e3aeade0d6f73101bc8ea9951737e1aa1f35c582?hp=35d9ac0686a4af87a25fc342880d2af5ac33d17e

linking commands on the individual window level, otherwise built-in handlers override our own (eg Paste is handled internally in a textcontrol without going through our own, resulting in changing 'read-only' unicode textcontrol)
