BBjFileChooser::setView
Description
In BBj 20.30 and higher, this method attempts to set the BBjFileChooser view. This functionality is dependent on the BBjFileChooser configuration and the client look and feel; some environments will ignore this method.
Syntax

|---|---|
| void | setView(boolean detail, int column, int order, ...) |
Parameters
| Parameter | Description | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| detail | true (1) for detail view, false (0) for grid view. | ||||||||
| column | Zero-based column number in the detail view. | ||||||||
| order |
|
||||||||
| ... |
Multiple column, order pairs may be specified, although the look and feel may only honor the first pair. |

This functionality can only make a best-effort attempt to honor the specified view settings. This method may be ignored in some BBjFileChooser configurations and some look and feel environments.
