| The Fl_File_Chooser::sort member specifies the sort function that is |
| used when loading the contents of a directory and can be customized |
| at run-time. |
| |
| The Fl_File_Chooser class also exports the Fl_File_Chooser::newButton |
| and Fl_File_Chooser::previewButton widgets so that application developers |
| can control their appearance and use. For more complex customization, |
| consider copying the FLTK file chooser code and changing it accordingly. |

| /** @} */ |
| |
| /** \fn Fl_File_Chooser::Fl_File_Chooser(const char *pathname, const char *pattern, int type, const char *title) |
| The constructor creates the Fl_File_Chooser dialog shown. |
| The pathname argument can be a directory name or a |
| complete file name (in which case the corresponding file is highlighted |
| in the list and in the filename input field.) |
| |
| The pattern argument can be a NULL |
| string or "*" to list all files, or it can be a |
| series of descriptions and filter strings separated by tab |
| characters (\\t). The format of filters is either |
| "Description text (patterns)" or just "patterns". A file chooser |
| that provides filters for HTML and image files might look like: |
| |
| \code |
| "HTML Files (*.html)\tImage Files (*.{bmp,gif,jpg,png})" |
| \endcode |
| |
| The file chooser will automatically add the "All Files (*)" |
| pattern to the end of the string you pass if you do not provide |
| one. The first filter in the string is the default filter. |
| |
| See the FLTK documentation on fl_filename_match() |
| for the kinds of pattern strings that are supported. |
| |
| The type argument can be one of the following: |
| |
| \li \c SINGLE - allows the user to select a single, existing file. |
| \li \c MULTI - allows the user to select one or more existing files. |
| \li \c CREATE - allows the user to select a single, existing file or |
| specify a new filename. |
| \li \c DIRECTORY - allows the user to select a single, existing directory. |
| |
| The title argument is used to set the title bar text for the |
| Fl_File_Chooser window. |
