Cocoa: setting the key equivalent
Example for Swift 2.0:
let key = String(utf16CodeUnits: [unichar(NSBackspaceCharacter)], count: 1) as String
item.keyEquivalentModifierMask = Int(NSEventModifierFlags.CommandKeyMask.rawValue | NSEventModifierFlags.ControlKeyMask.rawValue)
item.keyEquivalent = key
The setKeyEquivalent:
method is used to specify the character which triggers the command, but not the modifiers. It will set default modifiers by examining the character you pass. If you pass a lowercase character, it will use just command. If you pass an uppercase character, it will use shift+command. Because of this, you simply need to do this for shift+command+x:
[menuItem setKeyEquivalent:@"X"];
If you want to use other modifiers, you then call setKeyEquivalentModifierMask:
with the proper constants, chosen from NSShiftKeyMask
, NSAlternateKeyMask
(option), NSCommandKeyMask
, and NSControlKeyMask
.
The modifier key masks are just that: masks, not characters. You can't insert them into the key equivalent string. To apply them, use setKeyEquivalentModifierMask:
[menuItem setKeyEquivalentModifierMask: NSShiftKeyMask | NSCommandKeyMask];
[menuItem setKeyEquivalent:@"x"];
As with any other mask, use the bitwise OR operator |
to form combinations. See "Setting a Menu Item's Key Equivalent" for more details.
