  10     @class wxDirDialog
  11
  12     This class represents the directory chooser dialog.
  13
  14     @beginStyleTable
  15     @style{wxDD_DEFAULT_STYLE}
  16            Equivalent to a combination of wxDEFAULT_DIALOG_STYLE and
  17            wxRESIZE_BORDER (the last one is not used under wxWinCE).
  18     @style{wxDD_DIR_MUST_EXIST}
  19            The dialog will allow the user to choose only an existing folder.
  20            When this style is not given, a "Create new directory" button is
  21            added to the dialog (on Windows) or some other way is provided to
  22            the user to type the name of a new folder.
  23     @style{wxDD_CHANGE_DIR}
  24            Change the current working directory to the directory chosen by the
  25            user.
  26     @endStyleTable
  27
  28     Notice that @c wxRESIZE_BORDER has special side effect under recent (i.e.
  29     later than Win9x) Windows where two different directory selection dialogs
  30     are available and this style also implicitly selects the new version as the
  31     old one always has fixed size. As the new version is almost always
  32     preferable, it is recommended that @c wxRESIZE_BORDER style be always used.
  33     This is the case if the dialog is created with the default style value but
  34     if you need to use any additional styles you should still specify @c
  35     wxDD_DEFAULT_STYLE unless you explicitly need to use the old dialog version
  36     under Windows. E.g. do
  37     @code
  38         wxDirDialog dlg(NULL, "Choose input directory", "",
  39                         wxDD_DEFAULT_STYLE | wxDD_DIR_MUST_EXIST);
  40     @endcode
  41     instead of just using @c wxDD_DIR_MUST_EXIST style alone.
