## Detailed Description

This control can be used to place a directory listing (with optional files) on an arbitrary window.

The control contains a wxTreeCtrl window representing the directory hierarchy, and optionally, a wxChoice window containing a list of filters.

## Styles

- wxDIRCTRL_DIR_ONLY:
  Only show directories, and not files.
- wxDIRCTRL_3D_INTERNAL:
  Use 3D borders for internal controls.
- wxDIRCTRL_SELECT_FIRST:
  When setting the default path, select the first file in the directory.
- wxDIRCTRL_EDIT_LABELS:

- wxDIRCTRL_MULTIPLE:
  Allows multiple files and folders to be selected.
