318 | ||
319 | The <b>wx.MimeTypesManager</b> class allows the application to retrieve the | |
320 | information about all known MIME types from a system-specific location and the | |
321 | filename extensions to the MIME types and vice versa. After initialization the | |
322 | methods <b>GetFileTypeFromMimeType()</b> and <b>GetFileTypeFromExtension()</b> | |
323 | may be called: they will return a <b>wx.FileType</b> object which may be further | |
324 | queried for file description, icon and other attributes. | |
325 | ||
326 | A global instance of <b>wx.MimeTypesManager</b> is always available as | |
327 | <b>wx.TheMimeTypesManager</b>. It is recommended to use this instance instead | |
328 | of creating your own because gathering MIME information may take quite a long | |
329 | on Unix systems. | |
330 | ||
331 | This demo shows how to use wx.TheMimeTypesManager to list all known MIME types | |
332 | and retrieve that information as a wx.FileType from either an extension or | |
333 | MIME type. | |
334 | ||
335 | For further information please consult the wxWindows documentation for | |
336 | <b>wx.MimeTypesManager</b> and <b>wx.FileType</b>. | |
