     int mode)
  
  

Creates a new native file dialog. You should only have one such dialog opened at a time.

Parameters:

\[bu]

initial_path: The initial search path and filename. Can be NULL. To start with a blank file name the string should end with a directory separator (this should be the common case).

\[bu]

title: Title of the dialog.

\[bu]

patterns: A list of semi-colon separated patterns to match. You should always include the pattern "*.*" as usually the MIME type and not the file pattern is relevant. If no file patterns are supported by the native dialog, this parameter is ignored.

\[bu]

mode: 0, or a combination of the flags below.

Possible flags for the \[aq]flags\[aq] parameter are:

ALLEGRO_FILECHOOSER_FILE_MUST_EXIST

If supported by the native dialog, it will not allow entering new names, but just allow existing files to be selected. Else it is ignored.

ALLEGRO_FILECHOOSER_SAVE

If the native dialog system has a different dialog for saving (for example one which allows creating new directories), it is used. Else ignored.

ALLEGRO_FILECHOOSER_FOLDER

If there is support for a separate dialog to select a folder instead of a file, it will be used.

ALLEGRO_FILECHOOSER_PICTURES

If a different dialog is available for selecting pictures, it is used. Else ignored.

ALLEGRO_FILECHOOSER_SHOW_HIDDEN

If the platform supports it, also hidden files will be shown.

ALLEGRO_FILECHOOSER_MULTIPLE

If supported, allow selecting multiple files.

Returns:

A handle to the dialog which you can pass to al_show_native_file_dialog(3alleg5) to display it, and from which you then can query the results. When you are done, call al_destroy_native_file_dialog(3alleg5) on it.

If a dialog window could not be created then this function returns NULL.
