@class wxGenericDirCtrl
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.
@beginStyleTable
@style{wxDIRCTRL_DIR_ONLY}
Only show directories, and not files.
@style{wxDIRCTRL_3D_INTERNAL}
Use 3D borders for internal controls. This is the default.
@style{wxDIRCTRL_SELECT_FIRST}
When setting the default path, select the first file in the
directory.
@style{wxDIRCTRL_SHOW_FILTERS}
Show the drop-down filter list.
@style{wxDIRCTRL_EDIT_LABELS}
Allow the folder and file labels to be editable.
@style{wxDIRCTRL_MULTIPLE}
Allows multiple files and folders to be selected.

@beginEventEmissionTable
@event{EVT_DIRCTRL_SELECTIONCHANGED(id, func)}
Selected directory has changed.
Processes a @c wxEVT_DIRCTRL_SELECTIONCHANGED event type.
Notice that this event is generated even for the changes done by the
program itself and not only those done by the user.
Available since wxWidgets 2.9.5.
@event{EVT_DIRCTRL_FILEACTIVATED(id, func)}
The user activated a file by double-clicking or pressing Enter.
Available since wxWidgets 2.9.5.
