Disabled key equivalents passed throughPrior to Leopard, key
equivalents corresponding to disabled menu items would be ignored.
In Leopard, your application now has a chance to handle these. For
example, a key equivalent for control-K on a disabled menu item....
Thank you, Corbin. I understand the pass-through now, but I still
have an issue:
"cmd+upArrow" != "upArrow"
When I type cmd-upArrow, and myAction is disabled, the NSOutlineView
executes the action (moving the selection up) which I thought was
assigned to upArrow.
This seems to be incorrect, unless BOTH keyboard equivalents upArrow
^and^ cmd+upArrow are assigned to NSTable/OutlineView's
"moveSelectionUp" action. I'm not sure, because I cannot find any
documentation on precisely what are keyboard equivalents in NSTable/
OutlineView. I realize that upArrow is not really a keyboard
equivalent, more an over-ride of -keyDown, but the idea is the same.
That's true! Basically, NSTableView doesn't use the key equiv stuff
(in other words, -interpretKeyEvents: isn't called, for various
reasons), and overrides -keyDown: to do its logic. It doesn't stop
doing stuff if cmd is down; in fact, it never has. I've had requests
to make cmd-up/down move to the first/last rows, but there are various
compatibility reasons why we don't do that (ie: it conflicts with
Finder and open/save shortcuts).
It sounds like you think it is incorrect to have NSTableView handle
cmd-up/down like plain up/down. Please log a bug for this; I'll
consider changing it.
You can work around it by overriding -keyDown: in a nstableview
subclass and not calling super if it is cmd + (up/down).
