BAppFileInfo: Add method versions that don't touch the MIME DB
Add SetSupportedTypes() and SetIcon[ForType]() versions with an additional bool updateMimeDB parameter. If false, the method doesn't update the MIME DB entries for the type.

\fn status_t BAppFileInfo::SetSupportedTypes(const BMessage* types,

|
||||
\brief Sets the MIME types that are supported by the application and allows
|
||||
you to specify whether or not the supported types in the MIME DB shall
|
||||
be updated as well.
|
||||
|
||||
If \a types is \c NULL then the application's supported types are unset.
|
||||
|
||||
The supported MIME types must be stored in a field "types" of type
|
||||
\c B_STRING_TYPE in \a types.
|
||||
|
||||
If \a updateMimeDB is \c true, the method will inform the registrar about
|
||||
this news. In this case for each supported type the result of
|
||||
BMimeType::GetSupportingApps() will afterward include the signature of this
|
||||
application. That is, the application file needs to have a signature set.
|
||||
|
||||
\a syncAll specifies whether the no longer supported types shall be
|
||||
updated as well, i.e. whether or not this application shall be removed
|
||||
from the list of supporting applications. Only relevant when \a updateMimeDB
|
||||
is \c true.
|
||||
|
||||
\param types The supported types to be assigned to the file.
|
||||
May be \c NULL.
|
||||
\param updateMimeDB \c true to update the supported types in the MIME DB,
|
||||
\c false otherwise.
|
||||
\param syncAll \c true to also synchronize the no-longer supported
|
||||
types, \c false otherwise.
|
||||
|
||||
\returns A status code.
|
||||
\retval B_OK Everything went fine.
