## Constructor & Destructor Documentation

## ◆ BatchTool()

Digikam::BatchTool::BatchTool | ( | const QString & | name,
|  | BatchToolGroup | group,
|  | QObject *const | parent = `nullptr`
| ) |  |
| explicit

NOTE: these methods can be used safely in multi-threading part (ActionThread).

## Member Function Documentation

## ◆ apply()

bool Digikam::BatchTool::apply | ( |  | ) |

This method call customized toolOperations().

## ◆ applyFilter()

void Digikam::BatchTool::applyFilter | ( | DImgThreadedFilter *const | filter | ) |
| protected

Will call startFilterDirectly and apply the result to image().

## ◆ cancel()

void Digikam::BatchTool::cancel | ( |  | ) |
| virtual

to call a dedicated method to kill sub-threads parented to this tool instance. Unforget to call parent BatchTool::cancel() method in your customized implementation.

## ◆ clone()

virtual BatchTool * Digikam::BatchTool::clone | ( | QObject *const | parent = `nullptr` | ) | const
| pure virtual

It's a safe construction of tools instance used in multithreading (ActionThread) to process items in parallel.

## ◆ isCancelled()

bool Digikam::BatchTool::isCancelled | ( |  | ) | const
| protected

Use this method to stop loop in your toolOperations() implementation.

## ◆ outputSuffix()

QString Digikam::BatchTool::outputSuffix | ( |  | ) | const
| virtual

Typically, this is used with tool which convert to new file format. This method return and empty string by default.

## ◆ registerSettingsWidget()

void Digikam::BatchTool::registerSettingsWidget | ( |  | ) |
| virtual

Default implementation assign no settings view (a message label is just displayed). You need to call default implementation in your child class to init default signals and slots connections, after to have instanced your dedicated settings widget.

## ◆ savefromDImg()

bool Digikam::BatchTool::savefromDImg | ( |  | ) | const

- output Url set by setOutputUrl() or setOutputUrlFromInputUrl()
- output file format set by outputSuffix(). If this one is empty, format of original image is used instead.

## ◆ setOutputUrlFromInputUrl()

void Digikam::BatchTool::setOutputUrlFromInputUrl | ( |  | ) |

if outputSuffix() return null, file extension is the same than original.

## ◆ setSettings()

void Digikam::BatchTool::setSettings | ( | const BatchToolSettings & | settings | ) |

See BatchToolSettings container for details.

## ◆ settingsWidget()

QWidget * Digikam::BatchTool::settingsWidget | ( |  | ) | const

Return dedicated settings widget registered with registerSettingsWidget().

## ◆ signalAssignSettings2Widget

void Digikam::BatchTool::signalAssignSettings2Widget | ( |  | ) |
| signal

See registerSettingsWidget() implementation.

## ◆ slotAssignSettings2Widget

virtual void Digikam::BatchTool::slotAssignSettings2Widget | ( |  | ) |
| protected pure virtual slot

This method is called by setSettings() through signalAssignSettings2Widget().

## ◆ toolGroup()

BatchTool::BatchToolGroup Digikam::BatchTool::toolGroup | ( |  | ) | const

See BatchToolGroup enum for details.

## ◆ toolOperations()

virtual bool Digikam::BatchTool::toolOperations | ( |  | ) |
| protected pure virtual

This method is called by apply().

## ◆ toolVersion()

virtual int Digikam::BatchTool::toolVersion | ( |  | ) | const
| inline virtual

By default, ID is 1. Re-implement this method and increase this ID when tool settings change.
