TreeViewSearchEqualFunc    
    typealias TreeViewSearchEqualFunc = (model: TreeModel, <Error class: unknown class>, key: String, iter: TreeIter) -> Boolean(source)
A function used for checking whether a row in @model matches a search key string entered by the user. Note the return value is reversed from what you would normally expect, though it has some similarity to strcmp() returning 0 for equal strings.
