Detailed Description
Provides information about I/O (Internet, etc.) settings chosen/set by the end user.
KProtocolManager has a heap of static functions that allows only read access to KDE's IO related settings. These include proxy, cache, file transfer resumption, timeout and user-agent related settings.
The information provided by this class is generic enough to be applicable to any application that makes use of KDE's IO sub-system. Note that this mean the proxy, timeout etc. settings are saved in a separate user-specific config file and not in the config file of the application.

KProtocolInfo::FileNameUsedForCopying KProtocolManager::fileNameUsedForCopying | ( | const KUrl & | url | ) | [static] |
This setting defines the strategy to use for generating a filename, when copying a file or directory to another directory.
By default the destination filename is made out of the filename in the source URL. However if the ioslave displays names that are different from the filename of the URL (e.g. kio_fonts shows Arial for arial.ttf, or kio_trash shows foo.txt and uses some internal URL), using Name means that the display name (UDS_NAME) will be used to as the filename in the destination directory.
