Detailed Description
Information about I/O (Internet, etc.) protocols supported by KDE.
KProtocolInfo is useful if you want to know which protocols KDE supports. In addition you can find out lots of information about a certain protocol. All of the functionality is provided by the static methods. The implementation scans the *.protocol files of all installed KIO workers to get this information and stores the result into an internal cache.
*.protocol files are installed in the "services" resource.
The KProtocolInfo methods are reentrant (i.e. can be called from multiple threads simultaneously).

Member Enumeration Documentation
◆ FileNameUsedForCopying
enum KProtocolInfo::FileNameUsedForCopying |
Definition at line 330 of file kprotocolinfo.h.
◆ Type
enum KProtocolInfo::Type |
Describes the type of a protocol.
For instance ftp:// appears as a filesystem with folders and files, while bzip2:// appears as a single file (a stream of data), and telnet:// doesn't output anything.

Member Function Documentation
◆ archiveMimetypes()
|
static |
Returns the list of archive MIME types handled by the KIO worker implementing this protocol.
This corresponds to the "archiveMimetype=" field in the protocol description file.
- Parameters
-
protocol the protocol to check
- Returns
- the list of archive MIME types (e.g. application/x-zip) handled.
- Since
- 5.23
Definition at line 279 of file kprotocolinfo.cpp.
◆ capabilities()
|
static |
Returns the list of capabilities provided by the KIO worker implementing this protocol.
This corresponds to the "Capabilities=" field in the protocol description file.
The capability names are not defined globally, they are up to each worker implementation. For example when adding support for a new special command for mounting, one would add the string "Mount" to the capabilities list, and applications could check for that string before sending a special() command that would otherwise do nothing on older KIO worker implementations.
- Parameters
-
protocol the protocol to check
- Returns
- the list of capabilities.
Definition at line 269 of file kprotocolinfo.cpp.
◆ config()
Returns the name of the config file associated with the specified protocol.
This is useful if two similar protocols need to share a single config file, e.g. http and https.
This corresponds to the "config=" field in the protocol description file. The default is the protocol name, see name()
- Parameters
-
protocol the protocol to check
- Returns
- the config file, or an empty string if unknown
Definition at line 170 of file kprotocolinfo.cpp.
◆ defaultMimetype()
Returns the default MIME type for the specified protocol, if one exists.
This corresponds to the "defaultMimetype=" field in the protocol description file.
- Parameters
-
protocol the protocol to check
- Returns
- the default MIME type of the protocol, or an empty string if none set or protocol unknown
- Since
- 5.60
Definition at line 230 of file kprotocolinfo.cpp.
◆ determineMimetypeFromExtension()
|
static |
Returns whether MIME types can be determined based on extension for this protocol.
For some protocols, e.g. http, the filename extension in the URL can not be trusted to truly reflect the file type.
This corresponds to the "determineMimetypeFromExtension=" field in the protocol description file. Valid values for this field are "true" (default) or "false".
- Parameters
-
protocol the protocol to check
- Returns
- true if the MIME types can be determined by extension
Definition at line 201 of file kprotocolinfo.cpp.
◆ docPath()
Returns the documentation path for the specified protocol.
This corresponds to the "X-DocPath=" or "DocPath=" field in the protocol description file.
- Parameters
-
protocol the protocol to check
- Returns
- the docpath of the protocol, or an empty string if unknown
Definition at line 240 of file kprotocolinfo.cpp.
◆ exec()
Returns the library / executable to open for the protocol protocol
Example : "kio_ftp", meaning either the executable "kio_ftp" or the library "kio_ftp.la" (recommended), whichever is available.
This corresponds to the "exec=" field in the protocol description file.
- Parameters
-
protocol the protocol to check
- Returns
- the executable of library to open, or QString() for unsupported protocols
- See also
- KUrl::protocol()
Definition at line 211 of file kprotocolinfo.cpp.
◆ extraFields()
|
static |
Definition of extra fields in the UDS entries, returned by a listDir operation.
This corresponds to the "ExtraNames=" and "ExtraTypes=" fields in the protocol description file. Those two lists should be separated with ',' in the protocol description file. See ExtraField for details about names and types
Definition at line 220 of file kprotocolinfo.cpp.
◆ icon()
Returns the name of the icon, associated with the specified protocol.
This corresponds to the "Icon=" field in the protocol description file.
- Parameters
-
protocol the protocol to check
- Returns
- the icon of the protocol, or an empty string if unknown
Definition at line 155 of file kprotocolinfo.cpp.
◆ isFilterProtocol() [1/2]
|
static |
Same as above except you can supply just the protocol instead of the whole URL.
Definition at line 144 of file kprotocolinfo.cpp.
◆ isFilterProtocol() [2/2]
|
static |
Returns whether the protocol can act as a filter protocol.
A filter protocol can operate on data that is passed to it but does not retrieve/store data itself, like gzip. A filter protocol is the opposite of a source protocol.
The "source=" field in the protocol description file determines whether a protocol is a source protocol or a filter protocol. Valid values for this field are "true" (default) for source protocol or "false" for filter protocol.
- Parameters
-
url the url to check
- Returns
- true if the protocol is a filter (e.g. gzip), false if the protocol is a helper or source
Definition at line 301 of file kprotocolinfo.cpp.
◆ isHelperProtocol() [1/2]
|
static |
Same as above except you can supply just the protocol instead of the whole URL.
Definition at line 311 of file kprotocolinfo.cpp.
◆ isHelperProtocol() [2/2]
|
static |
Returns whether the protocol can act as a helper protocol.
A helper protocol invokes an external application and does not return a file or stream.
This corresponds to the "helper=" field in the protocol description file. Valid values for this field are "true" or "false" (default).
- Parameters
-
url the url to check
- Returns
- true if the protocol is a helper protocol (e.g. vnc), false if not (e.g. http)
Definition at line 306 of file kprotocolinfo.cpp.
◆ isKnownProtocol() [1/2]
|
static |
Same as above except you can supply just the protocol instead of the whole URL.
Definition at line 326 of file kprotocolinfo.cpp.
◆ isKnownProtocol() [2/2]
|
static |
Returns whether a protocol is installed that is able to handle url
.
- Parameters
-
url the url to check
- Returns
- true if the protocol is known
- See also
- name()
Definition at line 321 of file kprotocolinfo.cpp.
◆ maxWorkers()
|
static |
Returns the soft limit on the number of KIO workers for this protocol.
This limits the number of workers used for a single operation, note that multiple operations may result in a number of instances that exceeds this soft limit.
This corresponds to the "maxInstances=" field in the protocol's worker metadata. The default is 1.
- Parameters
-
protocol the protocol to check
- Returns
- the maximum number of workers, or 1 if unknown
- Since
- 5.101
Definition at line 181 of file kprotocolinfo.cpp.
◆ maxWorkersPerHost()
|
static |
Returns the limit on the number of KIO workers for this protocol per host.
This corresponds to the "maxInstancesPerHost=" field in the protocol's worker metadata. The default is 0 which means there is no per host limit.
- Parameters
-
protocol the protocol to check
- Returns
- the maximum number of workers, or 1 if unknown
- Since
- 5.101
Definition at line 191 of file kprotocolinfo.cpp.
◆ protocolClass()
Returns the protocol class for the specified protocol.
This corresponds to the "Class=" field in the protocol description file.
The following classes are defined:
- ":internet" for common internet protocols
- ":local" for protocols that access local resources
Protocol classes always start with a ':' so that they can not be confused with the protocols themselves.
- Parameters
-
protocol the protocol to check
- Returns
- the class of the protocol, or an empty string if unknown
Definition at line 250 of file kprotocolinfo.cpp.
◆ protocols()
|
static |
Returns list of all known protocols.
- Returns
- a list of all known protocols
Definition at line 139 of file kprotocolinfo.cpp.
◆ proxiedBy()
Returns the name of the protocol through which the request will be routed if proxy support is enabled.
A good example of this is the ftp protocol for which proxy support is commonly handled by the http protocol.
This corresponds to the "ProxiedBy=" in the protocol description file.
- Deprecated
- since 6.4, not used.
Definition at line 290 of file kprotocolinfo.cpp.
◆ showFilePreview()
|
static |
Returns whether file previews should be shown for the specified protocol.
This corresponds to the "ShowPreviews=" field in the protocol description file.
