Namespace sh::detailcolumns¶

namespace sh::detailcolumns

Implementations of detail columns.

Subclasses of sh::filesystem::DetailColumn (and possibly some auxiliary stuff). They are shown in the fileviews and can be queried in code.

class DetailColumnCustomAttributes : public sh::filesystem::DetailColumn, public sh::base::Singleton

#include <detailcolumncustomattributes.h>

Detail column which determines the custom attributes.

Custom attributes are filesystem handler specific values about files (like permissions).

Public Functions

void applyValueByEurl(std::shared_ptr<const sh::filesystem::Eurl> eurl, sh::filesystem::Operation *op, QVariant value) override

QString name(): The internal unique name.

QString displayName(): The display name.

bool isValueAvailable(std::shared_ptr<FilesystemNode> node): Checks if a value for this detail is available for one given node.

QVariant value(std::shared_ptr<FilesystemNode> node, bool ignoreAged = false)

Returns the value for this detail for one given node.

Parameters

ignoreAged: If no value should be returned which is older than the last request (not useful for nearly all cases).

QString displayValue(std::shared_ptr<FilesystemNode> node, const sh::filesystem::FilesystemModelFileviewProxy *viewmodel): Returns the stringified value for this details for one given node considering the configuration of a view.

QVariant requestValue(std::shared_ptr<FilesystemNode> node, sh::filesystem::Operation *op = 0, bool withNodeValues = false, bool withOperationsCache = true): Requests to determine the value for this detail for one given node. Blocks until the value is available. Get it with the value method afterwards.

bool sort_doTypediff(): If sorting should separate files and directories.

int sort_order(std::shared_ptr<FilesystemNode> n1, std::shared_ptr<FilesystemNode> n2): The sorting order.

uint displayIndex(): Controls which place this column should get in the user interface.

QVariant computeValue(std::shared_ptr<FilesystemNode> node, sh::filesystem::Operation *op): Returns a freshly determined value for this column and the given node. It neither asks nor populates any caches or storages.

int defaultWidth()

bool isRightAligned()

void applyValueByEurl(std::shared_ptr<const sh::filesystem::Eurl> eurl, sh::filesystem::Operation *op, QVariant value)

Applies the detail value to a given eurl (without using any caches).

Used for transferring some details when a file transfer occurs.

Optionally implement the one of the applyValueBy… methods and register the instance with sh::filesystem::FilesystemOperation::addTransferrableDetailColumn. For performance reasons, you should decide to implement applyValueByEurl.

void applyValueByNode(std::shared_ptr<FilesystemNode> node, sh::filesystem::Operation *op, QVariant value)

Applies the detail value to a given node (without using any caches).

Used for transferring some details when a file transfer occurs.

Optionally implement the one of the applyValueBy… methods and register the instance with sh::filesystem::FilesystemOperation::addTransferrableDetailColumn. For performance reasons, you should decide to implement applyValueByEurl.

void doShutdown(): Executes singleton shutdown.

void shutdown(): Shutdown down this singleton.

bool isAlive(): Returns if this singleton is alive (true until its shutdown begins).

Public Static Functions

QMap<QString, QString> getMapByValue(QVariant val): Converts the QVariant(QString) from native detail column representation to a QString/QString map.

QVariant VALUE_UNAVAILABLE(): A special value expressing that the value is not yet available.

void registerKnownDetailColumn(QString name, std::shared_ptr<DetailColumn> column)

std::shared_ptr<DetailColumn> findKnownDetailColumn(QString name)

Public Static Attributes

const uint DISPLAYINDEX_CORE = 10000

const uint DISPLAYINDEX_INTERESTING = 20000

const uint DISPLAYINDEX_EXOTIC = 30000

Private Functions

DetailColumnCustomAttributes()

class DetailColumnDirectSymlinkTarget : public sh::filesystem::DetailColumn, public sh::base::Singleton

#include <detailcolumndirectsymlinktarget.h>

Detail column which determines the direct symlink target (by resolving a link once).

Public Functions

QString name(): The internal unique name.

QString displayName(): The display name.

bool isValueAvailable(std::shared_ptr<FilesystemNode> node): Checks if a value for this detail is available for one given node.

QVariant value(std::shared_ptr<FilesystemNode> node, bool ignoreAged = false)

Returns the value for this detail for one given node.

Parameters

ignoreAged: If no value should be returned which is older than the last request (not useful for nearly all cases).

QString displayValue(std::shared_ptr<FilesystemNode> node, const sh::filesystem::FilesystemModelFileviewProxy *viewmodel): Returns the stringified value for this details for one given node considering the configuration of a view.

QVariant requestValue(std::shared_ptr<FilesystemNode> node, sh::filesystem::Operation *op = 0, bool withNodeValues = false, bool withOperationsCache = true): Requests to determine the value for this detail for one given node. Blocks until the value is available. Get it with the value method afterwards.

bool sort_doTypediff(): If sorting should separate files and directories.

int sort_order(std::shared_ptr<FilesystemNode> n1, std::shared_ptr<FilesystemNode> n2): The sorting order.

uint displayIndex(): Controls which place this column should get in the user interface.

QVariant computeValue(std::shared_ptr<FilesystemNode> node, sh::filesystem::Operation *op): Returns a freshly determined value for this column and the given node. It neither asks nor populates any caches or storages.
