  10     @class wxFilePickerCtrl
  11
  12     This control allows the user to select a file. The generic implementation is
  13     a button which brings up a wxFileDialog when clicked. Native implementation
  14     may differ but this is usually a (small) widget which give access to the
  15     file-chooser dialog.
  16     It is only available if @c wxUSE_FILEPICKERCTRL is set to 1 (the default).
  17
  18     @beginStyleTable
  19     @style{wxFLP_DEFAULT_STYLE}
  20            The default style: includes wxFLP_OPEN | wxFLP_FILE_MUST_EXIST and,
  21            under wxMSW only, wxFLP_USE_TEXTCTRL.
  22     @style{wxFLP_USE_TEXTCTRL}
  23            Creates a text control to the left of the picker button which is
  24            completely managed by the wxFilePickerCtrl and which can be used by
  25            the user to specify a path (see SetPath). The text control is
  26            automatically synchronized with button's value. Use functions
  27            defined in wxPickerBase to modify the text control.
  28     @style{wxFLP_OPEN}
  29            Creates a picker which allows the user to select a file to open.
  30     @style{wxFLP_SAVE}
  31            Creates a picker which allows the user to select a file to save.
  32     @style{wxFLP_OVERWRITE_PROMPT}
  33            Can be combined with wxFLP_SAVE only: ask confirmation to the user
  34            before selecting a file.
  35     @style{wxFLP_FILE_MUST_EXIST}
  36            Can be combined with wxFLP_OPEN only: the selected file must be an
  37            existing file.
  38     @style{wxFLP_CHANGE_DIR}
  39            Change current working directory on each user file selection change.
  40     @endStyleTable
  41
  42
  43     @beginEventTable{wxFileDirPickerEvent}
  44     @event{EVT_FILEPICKER_CHANGED(id, func)}
  45         The user changed the file selected in the control either using the
  46         button or using text control (see wxFLP_USE_TEXTCTRL; note that in
  47         this case the event is fired only if the user's input is valid,
  48         e.g. an existing file path if wxFLP_FILE_MUST_EXIST was given).
