Public Member Functions | |
QgsLayoutManager (QgsProject *project=nullptr) | |
Constructor for QgsLayoutManager. | |
~QgsLayoutManager () override | |
bool | accept (QgsStyleEntityVisitorInterface *visitor) const |
Accepts the specified style entity visitor, causing it to visit all style entities associated within the contained layouts. | |
bool | addLayout (QgsMasterLayoutInterface *layout) |
Adds a layout to the manager. | |
void | clear () |
Removes and deletes all layouts from the manager. | |
QgsMasterLayoutInterface * | duplicateLayout (const QgsMasterLayoutInterface *layout, const QString &newName) |
Duplicates an existing layout from the manager. | |
QString | generateUniqueTitle (QgsMasterLayoutInterface::Type type=QgsMasterLayoutInterface::PrintLayout) const |
Generates a unique title for a new layout of the specified type, which does not clash with any already contained by the manager. | |
QgsMasterLayoutInterface * | layoutByName (const QString &name) const |
Returns the layout with a matching name, or nullptr if no matching layouts were found. | |
QList< QgsMasterLayoutInterface * > | layouts () const |
Returns a list of all layouts contained in the manager. | |
QList< QgsPrintLayout * > | printLayouts () const |
Returns a list of all print layouts contained in the manager. | |

Removes a layout from the manager. | |
QDomElement | writeXml (QDomDocument &doc) const |
Returns a DOM element representing the state of the manager. | |
Manages storage of a set of layouts.
QgsLayoutManager handles the storage, serializing and deserializing of print layouts and reports. Usually this class is not constructed directly, but rather accessed through a QgsProject via QgsProject::layoutManager().
QgsLayoutManager retains ownership of all the layouts contained in the manager.

explicit |
Constructor for QgsLayoutManager.
The project will become the parent object for this manager.

|
override |
Definition at line 37 of file qgslayoutmanager.cpp.
bool QgsLayoutManager::accept | ( | QgsStyleEntityVisitorInterface * | visitor | ) | const |
Accepts the specified style entity visitor, causing it to visit all style entities associated within the contained layouts.
Returns true
if the visitor should continue visiting other objects, or false
if visiting should be canceled.
Definition at line 312 of file qgslayoutmanager.cpp.
bool QgsLayoutManager::addLayout | ( | QgsMasterLayoutInterface * | layout | ) |
Adds a layout to the manager.
Ownership of the layout is transferred to the manager. Returns true
if the addition was successful, or false
if the layout could not be added (eg as a result of a duplicate layout name).
Definition at line 42 of file qgslayoutmanager.cpp.
void QgsLayoutManager::clear | ( | ) |
Removes and deletes all layouts from the manager.
Definition at line 97 of file qgslayoutmanager.cpp.
QgsMasterLayoutInterface * QgsLayoutManager::duplicateLayout | ( | const QgsMasterLayoutInterface * | layout, |
const QString & | newName | ||
) |
Duplicates an existing layout from the manager.
The new layout will automatically be stored in the manager. Returns the new layout if duplication was successful.
Definition at line 262 of file qgslayoutmanager.cpp.
QString QgsLayoutManager::generateUniqueTitle | ( | QgsMasterLayoutInterface::Type | type = QgsMasterLayoutInterface::PrintLayout | ) | const |
Generates a unique title for a new layout of the specified type, which does not clash with any already contained by the manager.

QgsMasterLayoutInterface * QgsLayoutManager::layoutByName | ( | const QString & | name | ) | const |
Returns the layout with a matching name, or nullptr
if no matching layouts were found.
Definition at line 125 of file qgslayoutmanager.cpp.
|
signal |

Returns a list of all print layouts contained in the manager.
Definition at line 111 of file qgslayoutmanager.cpp.
bool QgsLayoutManager::readXml | ( | const QDomElement & | element, |
const QDomDocument & | doc | ||
) |

Definition at line 135 of file qgslayoutmanager.cpp.
bool QgsLayoutManager::removeLayout | ( | QgsMasterLayoutInterface * | layout | ) |
Removes a layout from the manager.
The layout is deleted. Returns true
if the removal was successful, or false
if the removal failed (eg as a result of removing a layout which is not contained in the manager).
