HotCocoa table_view and the doubleAction
by Dave Baldwin 01 Apr '09

01 Apr '09

I am having some difficulty on getting the double click action to work with a table view. I have code along the lines of: @tableView = table_view( :columns => [column(:id => :item, :title => '')], :data => @filteredData ) @tableView.doubleAction = 'doubleClickInRow:' def @tableView.doubleClickInRow (sender) NSLog "in double click" end When I run and double click on a row in the table I get: *** -[RBAnonymous132 doubleClickInRow:]: unrecognized selector sent to instance 0x8005d1c40 Does anyone know how to get this to work? Thanks, Dave.

macruby and sqlite3 gem
by Tim Rand 01 Apr '09

Hi Jordon, Thanks for the idea. I tried it (arch -arch i386 macirb), but get the same error. Tim Jordon suggested: "does not contain a version for the current architecture" sounds like a 32-bit vs. 64-bit problem to me. MacRuby 0.4 has both i386 and x86_64 archs for macruby and macirb, on a capable system it will pick the x86_64 arch first, which means any frameworks you load while running that arch need to have x86_64 in their Framework/library/bundle as well. What happens if you try running with something like `arch -arch i386 macruby` or `arch -arch i386 macirb` instead?

Accessing bytes within NSData
by Pete Yandell 01 Apr '09

01 Apr '09

I'd like to use something like Ruby's String#unpack to pull some info out of an NSData, but I'm stumped as to how to do it. NSData.bytes returns a Pointer object, but trying to use [] to dereference it gives me: ArgumentError: can't convert C/Objective-C value `0x800059800' of type `?_?' to Ruby object I've done a lot of digging around, reading of forum posts, playing (unsuccessfully) with BridgeSupport, etc., but it hasn't got me any closer. Any hints? The broader context is that I'm trying to extract the TCP port number from an NSSocketPort. NSSocketPort's address method returns an NSData, which should contain a sockaddr_in, out of which I should be able to pull the port. Thanks, Pete Yandell http://notahat.com/
