#259: [HotCocoa] add frame_color method and drawing to layout_view ---------------------------------+------------------------------------------ Reporter: dj2@… | Owner: lsansonetti@… Type: enhancement | Status: new Priority: minor | Milestone: Component: MacRuby | Keywords: ---------------------------------+------------------------------------------ The $DEBUG setting to change the frame colour of the layout views to red is handy. I've expanded it to allow setting arbitrary colours on the layout_views, which I found, makes it easier to position all of the layout views visually. -- Ticket URL: <http://www.macruby.org/trac/ticket/259> MacRuby <http://macruby.org/>

Problem with MacGem install
by Jonathan Waddilove 26 May '09

26 May '09

Matt, Thank you. It hadn't occured to me that the 'C' dependency would upset the MacGem process! I'll think about the issues of Ruby OpenGL v. Cocoa OpenGl. John, Thank you for sharing the examples... More reading to do :) Jonathan

Problem with MacGem install
by Jonathan Waddilove 26 May '09

26 May '09

Hi, I'm just starting to use MacRuby and I would like to be able to use OpenGL. So far I have been unable to install the GEM. I have just checked out the current MacRuby trunk (Mon 25 May) and after building it I get the following error: sudo macgem install ruby-opengl Password: macruby(37134,0x1037a5000) malloc: free_garbage: garbage ptr = 0x800031ca0, has non-zero refcount = 1 ERROR: While executing gem ... (RangeError) bignum too big to convert into `unsigned long long' Umm, is there a problem with the MacGem tool in the current drop or have I made a silly user error. Many thanks, Jonathan

A MacRuby-users group?
by Łukasz Adamczak 24 May '09

24 May '09

I'd like to propose the creation of macruby-users mailing list or an appropriate discussion board (the latter maybe even preferred). I'm thinking of a place for people using MacRuby for their apps, but not necessarily hacking on MacRuby itself. It feels a little intimidating to post to a "-devel" group, and I feel even I might be of some help to folks at a "-users" group. I don't mind starting something myself, but maybe an "official" discussion board is on the way. -- Regards, Łukasz Adamczak

Using AXObserverCreate with macruby
by Benjamin Mollenhauer 24 May '09

24 May '09

Hello, how can I use a ruby function as an parameter to AXObserverCreate? > extern AXError AXObserverCreate ( pid_t application, > AXObserverCallback callback, AXObserverRef *outObserver); It requires an AXObserverCallback, defined as > typedef void ( *AXObserverCallback)( > AXObserverRef observer, > AXUIElementRef element, > CFStringRef notification, > void *refcon); http://developer.apple.com/documentation/Accessibility/Reference/Accessibil… /apple%5Fref/c/tdef/AXObserverCallback I wrote a Obj.-C class (http://pastie.org/488213) to to access those functions, but how could I use ruby code as a callback? Any ideas? Ben

Crash with NSUInteger in delegate method
by Łukasz Adamczak 24 May '09

24 May '09

Don't know if it deserves a ticket, so I'm posting here first. I'm trying to use ObjectiveFlickr from my MacRuby project: http://github.com/czak/flickrtest One of the ObjectiveFlickr delegate methods receives NSUIntegers from the library: http://github.com/lukhnos/objectiveflickr/blob/b480aa39fa0e96f40a1b44523e0b… When I implement the delegate method in ruby (even an empty implementation): http://github.com/czak/flickrtest/blob/00ad51b155b65221770aa4ab1661fd99957a… ...I get a crash saying: Program received signal: “EXC_BAD_ACCESS”. warning: Could not find object file "/private/tmp/mrr/trunk/array.o" - no debug information available for "array.c". warning: Could not find object file "/private/tmp/mrr/trunk/bignum.o" - no debug information available for "bignum.c". warning: Could not find object file "/private/tmp/mrr/trunk/class.o" - no debug information available for "class.c". ... (a total of about 80 warnings for missing *.o files) Lukhnos (the author of ObjectiveFlickr) suggests it might be a case of primitive C types being passed to the delegate. Please advise - is it a bug in MacRuby that I should submit a ticket for or is there a way to avoid that? -- Regards, Łukasz Adamczak
