Re: NewEra 2.2 - Accelerators on child windows

This is a multi-part message in MIME format. --------------73F27B1BA26 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit This is expected behavior, and if you reference "accelerator" in the NewEra Help you'll see it's published. I doubt if it will change; if it does a bunch of my code breaks. Attached is a white paper I wrote up on how to make window-aware accelerators. If anyone wants it in non-MS Word form, let me know. I have a windows class "wnStandard", and a menu class "mnHotKey" that help implement the procedure outlined in the paper. I'll share on request (no warranty, natch), but please read the doc first to see if you really want/need it. Be also aware of a bug in NewEra 3.10TC1: Function-key accelerators of any combination (F#, Alt+F#, Ctrl+F#, etc) simply don't work. I have a patch request in place, but no dates as yet (discovered at the start of the week; ref bug #82644) Windy in here today, isn't it?
