@class wxDirDialog
This class represents the directory chooser dialog.
@beginStyleTable
@style{wxDD_DEFAULT_STYLE}
Equivalent to a combination of wxDEFAULT_DIALOG_STYLE and
wxRESIZE_BORDER.
@style{wxDD_DIR_MUST_EXIST}
The dialog will allow the user to choose only an existing folder.
When this style is not given, a "Create new directory" button is
added to the dialog (on Windows) or some other way is provided to
the user to type the name of a new folder.
@style{wxDD_CHANGE_DIR}
Change the current working directory to the directory chosen by the
user.
This flag cannot be used with the @c wxDD_MULTIPLE style.
@style{wxDD_MULTIPLE}
Allow the user to select multiple directories.
This flag is only available since wxWidgets 3.1.4
@style{wxDD_SHOW_HIDDEN}
Show hidden and system folders.
This flag is only available since wxWidgets 3.1.4
@endStyleTable
Notice that @c wxRESIZE_BORDER has special side effect under Windows
where two different directory selection dialogs are available and this
style also implicitly selects the new version as the old one always has
fixed size. As the new version is almost always preferable, it is
recommended that @c wxRESIZE_BORDER style be always used.
This is the case if the dialog is created with the default style value but
if you need to use any additional styles you should still specify @c
wxDD_DEFAULT_STYLE unless you explicitly need to use the old dialog version
under Windows. E.g. do
@code
wxDirDialog dlg(NULL, "Choose input directory", "",
wxDD_DEFAULT_STYLE | wxDD_DIR_MUST_EXIST);
@endcode
instead of just using @c wxDD_DIR_MUST_EXIST style alone.
@remarks MacOS 10.11+ does not display a title bar on the dialog. Use SetMessage()
to change the string displayed to the user at the top of the dialog after creation.
The SetTitle() method is provided for compatibility with pre-10.11 MacOS versions
that do still support displaying the title bar.
