Member Function Documentation

◆ accept()

bool QgsLayoutItemMarker::accept ( QgsStyleEntityVisitorInterface * visitor ) const

overridevirtual

Accepts the specified style entity visitor, causing it to visit all style entities associated with the layout item.

Returns true if the visitor should continue visiting other objects, or false if visiting should be canceled.

Since: QGIS 3.10

Reimplemented from QgsLayoutItem.

Definition at line 168 of file qgslayoutitemmarker.cpp.

◆ boundingRect()

QRectF QgsLayoutItemMarker::boundingRect ( ) const

override

Definition at line 158 of file qgslayoutitemmarker.cpp.

◆ create()

QgsLayoutItemMarker * QgsLayoutItemMarker::create ( QgsLayout * layout )

static

Returns a new marker item for the specified layout.

The caller takes responsibility for deleting the returned object.

Definition at line 51 of file qgslayoutitemmarker.cpp.

◆ draw()

void QgsLayoutItemMarker::draw ( QgsLayoutItemRenderContext & context )

overrideprotectedvirtual

Draws the item's contents using the specified item render context.

Note that the context's painter has been scaled so that painter units are pixels. Use the QgsRenderContext methods to convert from millimeters or other units to the painter's units.

Implements QgsLayoutItem.

Definition at line 180 of file qgslayoutitemmarker.cpp.

◆ finalizeRestoreFromXml()

void QgsLayoutItemMarker::finalizeRestoreFromXml ( )

overrideprotectedvirtual

Called after all pending items have been restored from XML.

Items can use this method to run steps which must take place after all items have been restored to the layout, such as connecting to signals emitted by other items, which may not have existed in the layout at the time readXml() was called. E.g. a scalebar can use this to connect to its linked map item after restoration from XML.

See also: readXml()

Reimplemented from QgsLayoutItem.

Definition at line 244 of file qgslayoutitemmarker.cpp.

◆ fixedSize()

QgsLayoutSize QgsLayoutItemMarker::fixedSize ( ) const

overridevirtual

Returns the fixed size of the item, if applicable, or an empty size if item can be freely resized.

See also: setFixedSize(); minimumSize()

Reimplemented from QgsLayoutItem.

Definition at line 163 of file qgslayoutitemmarker.cpp.

◆ icon()

QIcon QgsLayoutItemMarker::icon ( ) const

Reimplemented from QgsLayoutItem.

Definition at line 61 of file qgslayoutitemmarker.cpp.

◆ linkedMap()

QgsLayoutItemMap * QgsLayoutItemMarker::linkedMap ( ) const

Returns the linked rotation map, if set.

An nullptr means map rotation is disabled. If this is set then the marker is rotated by the same amount as the specified map object.

See also: setLinkedMap()

Definition at line 131 of file qgslayoutitemmarker.cpp.

◆ northArrowRotation()

double QgsLayoutItemMarker::northArrowRotation ( ) const

inline

When the marker is linked to a map in north arrow rotation mode, returns the current north arrow rotation for the marker.

See also: setLinkedMap()

Definition at line 93 of file qgslayoutitemmarker.h.

◆ northMode()

QgsLayoutNorthArrowHandler::NorthMode QgsLayoutItemMarker::northMode ( ) const

Returns the mode used to align the marker to a map's North.

See also: setNorthMode(); northOffset()

Definition at line 136 of file qgslayoutitemmarker.cpp.

◆ northOffset()

double QgsLayoutItemMarker::northOffset ( ) const

Returns the offset added to the marker's rotation from a map's North.

See also: setNorthOffset(); northMode()

Definition at line 148 of file qgslayoutitemmarker.cpp.

◆ readPropertiesFromElement()

bool QgsLayoutItemMarker::readPropertiesFromElement	(	const QDomElement &	element,

		const QgsReadWriteContext &	context
	)

overrideprotectedvirtual

Sets item state from a DOM element.

Parameters

element	is the DOM element for the item
document	DOM document
context	read write context

Note that item subclasses should not rely on all other items being present in the layout at the time this method is called. Instead, any connections and links to other items must be made in the finalizeRestoreFromXml() method. E.g. when restoring a scalebar, the connection to the linked map's signals should be implemented in finalizeRestoreFromXml(), not readPropertiesFromElement().

See also: writePropertiesToElement(); readXml()

Reimplemented from QgsLayoutItem.

Definition at line 218 of file qgslayoutitemmarker.cpp.

◆ setLinkedMap()

void QgsLayoutItemMarker::setLinkedMap ( QgsLayoutItemMap * map )

Sets the map object for rotation.

If this is set then the marker will be rotated by the same amount as the specified map object. This is useful especially for syncing north arrows with a map item.

See also: linkedMap()

Definition at line 126 of file qgslayoutitemmarker.cpp.

◆ setNorthMode()

void QgsLayoutItemMarker::setNorthMode ( QgsLayoutNorthArrowHandler::NorthMode mode )

Sets the mode used to align the marker to a map's North.
