Re: Why does menu item with shift-delete not work?
I think the key event is getting stolen by the first responder of whatever your
key window is at the time. I did a quick test and found the menu item did not
get invoked when a text view was selected but *did* get invoked when I removed
the text view.
I suspect a more precise technical answer lies in the docs on keyboard event
handling. See Cocoa Event Handling Guide = The Path of Key Events, in
particular the part about key equivalents:
https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/EventOverview/EventArchitecture/EventArchitecture.html#//apple_ref/doc/uid/1060i-CH3-SW10
A workaround would be to subclass NSApplication and override keyDown: to detect
Shift-Delete. Offhand, I'd think you could do something like
- (void)keyDown:(NSEvent *)theEvent
{
if ([self isShiftDeleteEvent:theEvent]
[[NSApp mainMenu performKeyEquivalent:theEvent])
{
return;
}
[super keyDown:theEvent];
}
But maybe someone has a better idea?

We have a menu item whose key equiv is shift-delete (backspace, not forward
delete). Typing that key does not even call the menu's performKeyEquivalent
method. How can we get this to work like it should?
BTW, I've already noticed that when you set the key equiv in IB, it sets it
to 8 (Unicode backspace), but when you type that key, the character in the
event is 127 (Unicode delete). Is that the problem? The OS just doesn't know
how to map it correctly? I had to remap 127 to 8 in our NSMenu subclass'
performKeyEquivalent method in order to get command-delete to work.
I've also tried programmatically changing the item's key equiv from 0x08 to
0x7f after installing the menu and that didn't help.

Offhand, I'd think you could do something like We already have a keyDown handler for the focused view, so it would be easy to catch it here and do the right thing. However, the menu is only alive when a certain tool is active, and I'd rather not muddy up all key event handling for this one case. We also already have install a local monitor in the app with addLocalMonitorForEventsMatchingMask, which handles other bugs in the Cocoa menu key handling, so our key events are already muddied up. Luckily, our non-menu-key handling code was written long before we added this key equiv to the menu item, so it falls back to that code. It's still wrong that Apple menus can't handle 100% of the keys that can be set in the menu items. They need to seriously work on Cocoa menu item key equivs and glyph handling and get it back on par with the features and Carbon menus offered. -- Steve Mills office: 952-818-3871 home: 952-401-6255 ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
