Detailed Description

FileUndoManager: makes it possible to undo kio jobs.

This class is a singleton, use self() to access its only instance.

Definition at line 37 of file fileundomanager.h.

Member Enumeration Documentation

CommandType

enum KIO::FileUndoManager::CommandType

The type of job.

Enumerator
Put	Represents the creation of a file from data in memory. Used when pasting data from clipboard or drag-n-drop. Since 4.7
Mkpath	Represents a KIO::mkpath() job. Since 5.4
BatchRename	Represents a KIO::batchRename() job. Used when renaming multiple files. Since 5.42

Definition at line 121 of file fileundomanager.h.

Member Function Documentation

currentCommandSerialNumber()

quint64 FileUndoManager::currentCommandSerialNumber

(

)

const

Definition at line 333 of file fileundomanager.cpp.

isUndoAvailable()

bool FileUndoManager::isUndoAvailable

(

)

const

Returns

true if undo is possible. Usually used for enabling/disabling the undo action.

Since

5.79

Definition at line 292 of file fileundomanager.cpp.

jobRecordingFinished

void KIO::FileUndoManager::jobRecordingFinished ( FileUndoManager::CommandType op )

signal

Emitted when a job that has been recorded by FileUndoManager::recordJob() or FileUndoManager::recordCopyJob has been finished.

The command is now available for an undo-operation.

jobRecordingStarted

void KIO::FileUndoManager::jobRecordingStarted ( CommandType op )

signal

Emitted when a job recording has been started by FileUndoManager::recordJob() or FileUndoManager::recordCopyJob().

After the job recording has been finished, the signal jobRecordingFinished() will be emitted.

newCommandSerialNumber()

quint64 FileUndoManager::newCommandSerialNumber

(

)

These two functions are useful when wrapping FileUndoManager and adding custom commands.

Each command has a unique ID. You can get a new serial number for a custom command with newCommandSerialNumber(), and then when you want to undo, check if the command FileUndoManager would undo is newer or older than your custom command.

Definition at line 328 of file fileundomanager.cpp.

recordCopyJob()

void FileUndoManager::recordCopyJob

(

KIO::CopyJob *

copyJob

)

Record this CopyJob while it's happening and add a command for it so that the user can undo it.

The signal jobRecordingStarted() is emitted.

Definition at line 267 of file fileundomanager.cpp.

recordJob()

void FileUndoManager::recordJob	(	CommandType	op,
		const QList< QUrl > &	src,
		const QUrl &	dst,
		KIO::Job *	job )

Record this job while it's happening and add a command for it so that the user can undo it.

The signal jobRecordingStarted() is emitted.

Parameters

op	the type of job - which is also the type of command that will be created for it
src	list of source urls. This is empty for Mkdir, Mkpath, Put operations.
dst	destination url
job	the job to record

Definition at line 260 of file fileundomanager.cpp.

self()

FileUndoManager * FileUndoManager::self ( )

static

Returns

the FileUndoManager instance

Definition at line 225 of file fileundomanager.cpp.

setUiInterface()

void FileUndoManager::setUiInterface

(

UiInterface *

ui

)

Set a new UiInterface implementation.

This deletes the previous one.

Parameters

ui	the UiInterface instance, which becomes owned by the undo manager.

Definition at line 684 of file fileundomanager.cpp.

uiInterface()

FileUndoManager::UiInterface * FileUndoManager::uiInterface

(

)

const

Returns

the UiInterface instance passed to setUiInterface. This is useful for calling setParentWidget on it. Never delete it!

Definition at line 689 of file fileundomanager.cpp.

undo

void FileUndoManager::undo ( )

slot

Undoes the last command Remember to call uiInterface()->setParentWidget(parentWidget) first, if you have multiple mainwindows.

This operation is asynchronous. undoJobFinished will be emitted once the undo is complete.

Definition at line 344 of file fileundomanager.cpp.

undoAvailable

void KIO::FileUndoManager::undoAvailable ( bool avail )

signal

Emitted when the value of isUndoAvailable() changes.

undoJobFinished

void KIO::FileUndoManager::undoJobFinished ( )

signal

Emitted when an undo job finishes. Used for unit testing.

undoText()

QString FileUndoManager::undoText

(

)

const

Returns

the current text for the undo action.

Definition at line 297 of file fileundomanager.cpp.

undoTextChanged

void KIO::FileUndoManager::undoTextChanged ( const QString & text )

signal

Emitted when the value of undoText() changes.
