# wxGenericDirCtrl (wx v2.6)

Copy Markdown View Source

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

This class supports the following styles:

- wxDIRCTRL_DIR_ONLY: Only show directories, and not files.

- wxDIRCTRL_3D_INTERNAL: Use 3D borders for internal controls. This is the default.

- wxDIRCTRL_SELECT_FIRST: When setting the default path, select the first file in the directory.

- wxDIRCTRL_SHOW_FILTERS: Show the drop-down filter list.

- wxDIRCTRL_EDIT_LABELS: Allow the folder and file labels to be editable.

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

This class is derived, and can use functions, from:

- `wxControl`

- `wxWindow`

- `wxEvtHandler`

# wxGenericDirCtrl()

    -type wxGenericDirCtrl() :: wx:wx_object().

## Functions

# collapseTree(This)

    -spec collapseTree(This) -> ok when This :: wxGenericDirCtrl().

# create(This, Parent)

    -spec create(This, Parent) -> boolean() when This :: wxGenericDirCtrl(), Parent :: wxWindow:wxWindow().

Equivalent to `create(This, Parent, [])`.

# create/3

    -spec create(This, Parent, [Option]) -> boolean()
                    when
                        This :: wxGenericDirCtrl(),
                        Parent :: wxWindow:wxWindow(),
                        Option ::
                            {id, integer()} |
                            {dir, unicode:chardata()} |
                            {pos, {X :: integer(), Y :: integer()}} |
                            {size, {W :: integer(), H :: integer()}} |
                            {style, integer()} |

                            {defaultFilter, integer()}.

Create function for two-step construction.

See `new/2` for details.

# destroy(This)
