Trying to put the finishing touched on a cross-platform app written using j602 JWD. Mostly developed on the Mac, which means that some unexpected behavior under Win2000 has gone unnoticed until now.
JVERSION Installer: j602a_win.exe Engine: j602/2008-03-03/16:45 Library: 6.02.056 Windows 2000 Version 5.0 (Build 2195: Service Pack 4) If my "wd" form definition contains the lines: menupop "File"; menu newtt "&New" "Ctrl+N" "Start a new ttable" "new"; menu opens "Open Sample" "Ctrl+Shift+O" "Open a sample ttable" "sample"; ... then I'd expect keying Ctrl+N would post sysevent: tab_newtt_button, and Ctrl+Shift+O would post sysevent: tab_opens_button . This is what happens on the Mac (keying ⌘ for Ctrl, which is a long-standing Mac convention for cross-platform products). However, under Win2000, Ctrl+N posts sysevent: tab_nctrl_fkey, and Ctrl+Shift+O posts sysevent: tab_octrlshift_fkey. All other hotkeys post sysevents named in the same vein. (Except for Ctrl+Z, Alt+G, Alt+H -- which seem to follow rules of their own.) These extra handlers are not difficult to provide, eg like this: tab_nctrl_fkey=: tab_newtt_button etc... whereupon the hotkeys works fine (apart of course from Ctrl+Z, Alt+G, Alt+H). I'd like to know: is this a bug or a feature? Where is it documented? Has it been there from the start, or is it a recent change to '~system/extras/util'? Can it be relied upon with all post-2000 Windows versions? What happens under Linux? Although I mostly use the Mac, I have written J apps to run under Win XP and I've never noticed this behavior before. Of course I may never actually have tried a hotkey. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
