 Notice that everything between [exBegin] and [exEnd] is extracted by the html-doc generator

 to create nicely formatted and clickable executable examples in the generated html-doc.

 (see the browsers class-documentation menu items for more)

 trying the widget as standAlone view:

                                                        [exBegin]

    HGChangesetLabelsView new open

                                                        [exEnd]

 embedded in another view:

                                                        [exBegin]

    |top v|

    top := StandardSystemView new.

    top extent:300@300.

    v := HGChangesetLabelsView new.

    v origin:10@10 corner:150@150.

    top add:v.

    top open

                                                        [exEnd]
