Class sh::detailcolumns::DetailColumnFilesize

class sh::detailcolumns::DetailColumnFilesize : public sh::filesystem::DetailColumn, public sh::base::Singleton

Detail column which determines the file size.

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).

bool isVisible()

If this detail shall be a visible column in the 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

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)
