## Detailed Description

This control allows the user to select a file.

The generic implementation is a button which brings up a wxFileDialog when clicked. Native implementation may differ but this is usually a (small) widget which give access to the file-chooser dialog. It is only available if `wxUSE_FILEPICKERCTRL` is set to 1 (the default).

## Styles

This class supports the following styles:

- wxFLP_DEFAULT_STYLE:
  The default style: includes wxFLP_OPEN | wxFLP_FILE_MUST_EXIST and, under wxMSW only, wxFLP_USE_TEXTCTRL.
- wxFLP_USE_TEXTCTRL:
  Creates a text control to the left of the picker button which is completely managed by the wxFilePickerCtrl and which can be used by the user to specify a path (see SetPath). The text control is automatically synchronized with button's value. Use functions defined in wxPickerBase to modify the text control.
- wxFLP_OPEN:
  Creates a picker which allows the user to select a file to open.
- wxFLP_SAVE:
  Creates a picker which allows the user to select a file to save.
- wxFLP_OVERWRITE_PROMPT:
  Can be combined with wxFLP_SAVE only: ask confirmation to the user before selecting a file.
- wxFLP_FILE_MUST_EXIST:
  Can be combined with wxFLP_OPEN only: the selected file must be an existing file.
- wxFLP_CHANGE_DIR:
  Change current working directory on each user file selection change.

## Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxFileDirPickerEvent& event)

Event macros for events emitted by this class:

- EVT_FILEPICKER_CHANGED(id, func):
  The user changed the file selected in the control either using the button or using text control (see wxFLP_USE_TEXTCTRL; note that in this case the event is fired only if the user's input is valid, e.g. an existing file path if wxFLP_FILE_MUST_EXIST was given).

  | pos | Initial position.
  | size | Initial size.
  | style | The window style, see wxFLP_* flags.
  | validator | Validator which can be used for additional data checks.
  | name | Control name.

Returns:
  true if the control was successfully created or false if creation failed.

wxFileName wxFilePickerCtrl::GetFileName | ( |  | ) | const

Similar to GetPath() but returns the path of the currently selected file as a wxFileName object.

wxString wxFilePickerCtrl::GetPath | ( |  | ) | const

Returns the absolute path of the currently selected file.

void wxFilePickerCtrl::SetFileName | ( | const wxFileName & | filename | ) |

This method does the same thing as SetPath() but takes a wxFileName object instead of a string.

void wxFilePickerCtrl::SetPath | ( | const wxString & | filename | ) |

Sets the absolute path of the currently selected file.
