Detailed Description

LayoutSaver allows to save or restore layouts.

You can save a layout to a file or to a byte array. JSON is used as the serialized format.

Example: LayoutSaver saver;

// Save to a file: saver.saveToFile(filename);

The counterpart of saveToFile() is restoreFromFile().

You can also save to a QByteArray instead, with serializeLayout(). The counterpart of serializeLayout() is restoreLayout();

Constructor & Destructor Documentation

◆ LayoutSaver()

LayoutSaver::LayoutSaver ( RestoreOptions options = RestoreOption_None )

explicit

Constructor. Construction on the stack is suggested.

Definition at line 99 of file LayoutSaver.cpp.

◆ ~LayoutSaver()

LayoutSaver::~LayoutSaver ( )

Destructor.

Definition at line 104 of file LayoutSaver.cpp.

Member Function Documentation

◆ dptr()

LayoutSaver::Private * LayoutSaver::dptr ( ) const

Definition at line 310 of file LayoutSaver.cpp.

◆ restoredDockWidgets()

DockWidgetBase::List LayoutSaver::restoredDockWidgets ( ) const

returns a list of dock widgets which were restored since the last restoreLayout() or restoreFromFile()

Useful since some dock widgets can be new, and hence not be included in the last saved layout.

Definition at line 315 of file LayoutSaver.cpp.

References QVector::push_back(), QVector::reserve(), and QVector::size().

◆ restoreFromFile()

bool LayoutSaver::restoreFromFile ( const QString & jsonFilename )

restores the layout from a JSON file

Parameters

jsonFilename the filename containing a saved layout

Returns: true on success

◆ restoreInProgress()

bool LayoutSaver::restoreInProgress ( )

static

returns whether a restore (restoreLayout) is in progress

Definition at line 419 of file LayoutSaver.cpp.

◆ restoreLayout()

bool LayoutSaver::restoreLayout ( const QByteArray & data )

restores the layout from a byte array All MainWindows and DockWidgets should have been created before calling this function.

If not all DockWidgets can be created beforehand then make sure to set a DockWidget factory via Config::setDockWidgetFactoryFunc()

See also: Config::setDockWidgetFactoryFunc()

Returns: true on success

◆ saveToFile()

bool LayoutSaver::saveToFile ( const QString & jsonFilename )

saves the layout to JSON file

Parameters

jsonFilename the filename where the layout will be saved to

Returns: true on success

Definition at line 109 of file LayoutSaver.cpp.

References QIODevice::errorString(), QFile::open(), serializeLayout(), QIODevice::write(), and QIODevice::WriteOnly.

◆ serializeLayout()

QByteArray LayoutSaver::serializeLayout ( ) const

saves the layout into a byte array

◆ setAffinityNames()

void LayoutSaver::setAffinityNames ( const QStringList & affinityNames )

Sets the list of affinity names for which restore and save will be applied on. Allows to save/restore only a subset of the windows. Empty by default, all windows are subject to save/restore. Any window with empty affinity will also be subject to save/restore, regardless of affinityNames.
