Just about all windows in FGII are 'custom' (there are very few built in to the FG engine, even the d20 and Foundation rulesets use custom windows).
A relatively simple example is the code for showing 'story' entries. It comprises a windowclass for listing the story entries (encounterlist), a windowclass which shows a single entry in the list (encountersmall), and a windowclass which displays the full story details (encounter):
<windowclass name="encounter">
<datasource>encounter</datasource>

<size>
<width>400</width>
<height>650</height>
