Detailed Description

The MimeType class provides MIME type information.

A MimeType object is a light-weight value which provides information about a MIME type.

Constructor & Destructor Documentation

MimeType::MimeType ( const QString & ext_or_id )

Constructs a MimeType. Normally, ext_or_id is a MIME type, but if ext_or_id starts with / or contains no /, it is interpretted as a filename and the extension (eg. .txt) is used as the MIME type.
Definition at line 148 of file mimetype.cpp.
References init().

MimeType::MimeType ( const DocLnk & lnk )

Constructs a MimeType from the type() of lnk.
Definition at line 156 of file mimetype.cpp.
References init(), and AppLnk::type().

Member Function Documentation

const AppLnk * MimeType::application ( ) const

Returns the AppLnk defining the application associated with this MIME type, or 0 if none is associated.
The caller must not retain the pointer, but of course you can dereference it to take a copy if needed.
