Method: JSON::Editor.data2model

Defined in:
lib/vendor/json_pure/lib/json/editor.rb

.data2model(data, model = nil, parent = nil) ⇒ Object

Convert the Ruby data structure data into tree model data for Gtk and returns the whole model. If the parameter model wasn’t given a new Gtk::TreeStore is created as the model. The parent parameter specifies the parent node (iter, Gtk:TreeIter instance) to which the data is appended, alternativeley the result of the yielded block is used as iter.
