enjoy! :) 2011/11/27 François Boone <francois.bo...@usherbrooke.ca>: > Hi, > In the same way that this tutorial > (http://developer.apple.com/library/mac/#featuredarticles/UsingMacRuby/_index.html), > I try to implement a NSOutlineView controller in ruby to make a simple tree > in the left part of a window. > I read the documentation of NSOutlineView, tasks and I understand I have to > write at least four methods in my controller class: > • – outlineView:child:ofItem: > • – outlineView:isItemExpandable: > • – outlineView:numberOfChildrenOfItem: > • – outlineView:objectValueForTableColumn:byItem: > My questions are: > 1) what kind of object I have to use in ruby to fit with outlineView > structure? > If I understand I need a structure like: > Parent_1 : child 1, child 2 > Parent_2 : no child > Parent_3 : child 1, child 2, child 3 > 2) Is a Hash like this: > Hash[ "Parent_1" => ["child 1", child 2"], "Parent_2", Parent_3 => ["child > 1", "child 2", "child_3"]] > can be the solution? > 3) where I can find this kind of information: the mapping between ruby data > structure and NSObject data structure (for future use)? > 4) and the last one: I think I do not understand what is item in the last > method: > – outlineView:objectValueForTableColumn:byItem: > item: An item in the data source in the specified tableColumn of the view. > So, if I want to make a simple tree, I should have just one column, and then > item should be Parent_x or child_x: Is it right? > > Thank you for reply > François > _______________________________________________ > MacRuby-devel mailing list > MacRuby-devel@lists.macosforge.org > http://lists.macosforge.org/mailman/listinfo.cgi/macruby-devel > _______________________________________________ MacRuby-devel mailing list MacRuby-devel@lists.macosforge.org http://lists.macosforge.org/mailman/listinfo.cgi/macruby-devel
