Detailed Description

Implements support of 3D map views in print layouts

Since
QGIS 3.4

Definition at line 37 of file qgslayoutitem3dmap.h.

Constructor & Destructor Documentation

◆ QgsLayoutItem3DMap()

QgsLayoutItem3DMap::QgsLayoutItem3DMap ( QgsLayout layout)

Constructor for QgsLayoutItem3DMap, with the specified parent layout.

Ownership is transferred to the layout.

Definition at line 27 of file qgslayoutitem3dmap.cpp.

◆ ~QgsLayoutItem3DMap()

Member Function Documentation

◆ assignFreeId()

void QgsLayoutItem3DMap::assignFreeId ( )

Sets the map id() to a number not yet used in the layout.

The existing id() is kept if it is not in use.

Definition at line 53 of file qgslayoutitem3dmap.cpp.

◆ cameraPose()

QgsCameraPose QgsLayoutItem3DMap::cameraPose ( ) const
inline

Returns camera view.

Definition at line 82 of file qgslayoutitem3dmap.h.

◆ create()

QgsLayoutItem3DMap * QgsLayoutItem3DMap::create ( QgsLayout layout)
static

Returns a new 3D map item for the specified layout.

The caller takes responsibility for deleting the returned object.

Definition at line 38 of file qgslayoutitem3dmap.cpp.

◆ displayName()

QString QgsLayoutItem3DMap::displayName ( ) const
overridevirtual

overridden to show "3D Map 1" type names

Reimplemented from QgsLayoutItem.

Definition at line 81 of file qgslayoutitem3dmap.cpp.

◆ draw()

void QgsLayoutItem3DMap::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 96 of file qgslayoutitem3dmap.cpp.

◆ finalizeRestoreFromXml()

void QgsLayoutItem3DMap::finalizeRestoreFromXml ( )
overridevirtual

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.

readXml()

Reimplemented from QgsLayoutItem.

Definition at line 230 of file qgslayoutitem3dmap.cpp.

◆ icon()

QIcon QgsLayoutItem3DMap::icon ( ) const
overridevirtual

Returns the item's icon.

Reimplemented from QgsLayoutItem.

Definition at line 48 of file qgslayoutitem3dmap.cpp.

◆ mapSettings()

Qgs3DMapSettings* QgsLayoutItem3DMap::mapSettings ( ) const
inline

Returns map scene. May be a null pointer if not yet configured.

Definition at line 91 of file qgslayoutitem3dmap.h.

◆ readPropertiesFromElement()

bool QgsLayoutItem3DMap::readPropertiesFromElement ( const QDomElement &  element,
const QDomDocument &  document,
const QgsReadWriteContext context 
)
overrideprotectedvirtual

Sets item state from a DOM element.

Parameters
elementis the DOM element for the item
documentDOM document
contextread 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().
