this class implements file selection boxes. Instances show a list of
|
|
0
|
34 |
files, and perform an action block with the selected pathname as
|
|
|
35 |
argument when ok is clicked.

There is an optional PatternField, which shows itself when a pattern
|
|
|
38 |
is defined. If there is such a pattern, only files matching the pattern
|
|
|
39 |
will be shown in the list (and directories).
