NSTextField eating Escape
by Ricky Sharp 30 Sep '05

30 Sep '05

site_archiver(a)lists.apple.com Delivered-To: cocoa-dev(a)lists.apple.com For a particular "screen", here's my UI hierarchy: IIContentWindow (custom NSWindow) IIBackground (custom NSView; window background) IIGraphic (custom NSView; dialog background) NSTextField IIButton (custom NSControl/NSActionCell; Cancel) IIButton (ditto; OK) ___________________________________________________________ Ricky A. Sharp mailto:rsharp@instantinteractive.com Instant Interactive(tm) http://www.instantinteractive.com _______________________________________________ Do not post admin requests to the list. They will be ignored. Cocoa-dev mailing list (Cocoa-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/cocoa-dev/site_archiver%40lists.appl… In my kiosk-type app, I use a completely custom UI (subclasses of NSControl, NSCell, etc.) However, one particular item I could not subclass and get working was NSTextField. But, I was able to use the standard NSTextField for my needs. To process key events, I've implemented keyDown: in IIContentWindow. This simply dispatches the event. One of my handlers knows how to deal with Escape and Return/Enter (to simulate clicks on Cancel and Default buttons). In the above hierarchy, IIBackground and IIGraphic cannot become key, and cannot be made the first responder. My button classes are just the opposite. Now then, whenever the text field has the keyboard focus, Escape does nothing. I've set breakpoints in my window's keyDown:, but that is never hit. It was only reached by some keys (e.g. many of the function keys). Escape, along with many navigational keys such as Home and End did nothing. And, as expected, you could enter text a- ok into the field with all the other keys or input methods. Since the text field's parent was an IIGraphic, I implemented keyDown: in there; thinking that the key event would be propagated to its parent. It too was never reached when I hit Escape. I tried allowing IIGraphic to become key and become the first responder, but that didn't change the outcome. Whenever the text field _did not_ have the keyboard focus (possible when full keyboard access is enabled), pressing Escape did the right thing. I know that a "normal" Cocoa window/dialog does not exhibit this behavior. For example, Safari's "Add Bookmark..." sheet allows Escape to toggle the Cancel button even when the bookmark text field has the keyboard focus. Is this just a limitation of the framework I have? Why is NSTextField not passing on the key event to my window? If there's no easy solution, I may just punt on this one; my app has only a single NSTextField in it.

Of course, that is a private method that I shouldn't use :-). How can I fetch the object value for a row and column if the table view is using bindings? There is no easy way to do this.

That is wrong..you don't need to recompile for a new version of the OS. You _may_ need to recompile to get certain AppKit features "turned on". We have some runtime link checks that only will do certain things if you compile on certain versions. This is to maintain as much compatability as possible.

how to implement equivalent of -[NSTableView _getFullyFormedCellAtColumn:row:]?

Note that return code is an entirely different animal - that's the integer value that's returned from main(). It has nothing to do with what's printed to stdout or stderr. You can access it with NSTask's - terminationStatus. But somehow App2 is always getting the same return code because maybe App1 is swallowing up App3's ouput since he is the overall parent of all of them. App2 needs to capture App3's stdout but for some reason it seems to be not returning correctly. Am I making any sense here??? Sorry, but "it seems to be not returning correct" is far too vague to answer with more than a guess. By default, if you don't override it, App2 will inherit stdout from App1, and App3 will inherit stdout from App2. But, it's trivial to override that default; if you want to capture App3's output, you simply create an NSPipe in App2 and pass that to NSTask's - setStandardOutput: before launching App3.
