As I relearn/learn how to use Pharo, Iâm struck by some of the excellent changes and confounded by some of the simple things that boggle me. So, I wanted to follow a path through some message sends - the use of #alert:title: in UIManager specifically. So I browser UIManager, find the method (its subclassResponsiblity) - so I find other implementers (cmd+b, cmd+m) - (Iâm really liking that there are more keystrokes in newer Pharoâs but not liking that the same operations donât have the same bindings in different windows - e.g. in the debugger - its not this!!) Anyway - this gives me an implementors window on TEasilyThemed - great! In the source, there is another msg send - ^self alert:title:configure: So I want to follow its implementers - I hi light the source and cmd+b,cmd+m does nothing? hmmm - right click there and the context menu doesnât have an obvious way - until I spot (Extended Searchâ¦) [which by the way should be shown as a submenu - like it does in the SystemBrowser). In this menu there is âimplementers of itâ - however this does nothing? (this is in both Pharo 3.0 and Pharo 4.0) So how do you trace through method calls? Am I doing something wrong - or has this been broken for a long time? Tim
