Hi. Is there any straightforward way to tell pointer position (x, y) upon keypress? In original wxWidgets, wxKeyEvent supports GetX() and GetY() methods, but wxRuby''s KeyEvent object does not have one. I also checked with event.methods and event.instance_variables. Do I need to keep track of pointer position by evt_motion? -- Taisuke Yamada <tyamadajp@spam.rakugaki.org>, http://rakugaki.org/ 2268 E9A2 D4F9 014E F11D 1DF7 DCA3 83BC 78E5 CD3A Message to my public address may not be handled in a timely manner.

...@klass.new end def evaluate(&blk) @klass.instance_eval(&blk) end attr_reader :klass alias_method :class, :klass end One of the behaviours of the AnonymousClass is that new can take a block, and eval the block in the anonymous class, represented by the @klass instance_variable: ac = AnonymousClass.new do include Enumerable end So is there a way to stub AnonymousClass.new such that it yield an AnonymousClass mock, as well as yielding to the block given? What are the technical challenges involved in implementing this in the mocking framework? Or is it a ma...

How can I find all the methods on an object from withing irb? Thanks, Joe

This is probably more of a Ruby question than a Rails question. I''ve always wondered exactly how controller instance variables are being made accessible to the ERb code in the views. In the Agile Rails book on pages 38, there''s a sidebar at the top that hints at what''s going on: "Rails does some Ruby magic so that the instance variables of the controller

I am trying to create an input form where subsets of the input data goes into separate rows of the table (events). I have created a proxy object (CompoundEvent) to hold all of the data, and overridden its "save" method to create the several tuples. This was almost working late last night when I did something that stopped the params[] hash from getting any information from the post

I''m having a problem converting a date retrieved from my MySQL database and I''m hoping someone can help. MySQL stores the date/time as this: 2005-03-08 17:00:34.0 and according to my Pickaxe book Ruby stores times as "the number of seconds and microseconds since [...] January 1, 1970". All well and good. Unfortunately, RoR is converting my date to this:
