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