Detailed Description

Layout graphical items for displaying a map.

Since: QGIS 3.0

Definition at line 36 of file qgslayoutitemmap.h.

Member Enumeration Documentation

◆ AtlasScalingMode

enum QgsLayoutItemMap::AtlasScalingMode

Scaling modes used for the serial rendering (atlas)

Enumerator

Fixed

The current scale of the map is used for each feature of the atlas.

Predefined

A scale is chosen from the predefined scales.

The smallest scale from the list of scales where the atlas feature is fully visible is chosen.

See also: QgsAtlasComposition::setPredefinedScales.

Note: This mode is only valid for polygon or line atlas coverage layers

Auto

The extent is adjusted so that each feature is fully visible.

A margin is applied around the center

See also: setAtlasMargin

Note: This mode is only valid for polygon or line atlas coverage layers

Definition at line 46 of file qgslayoutitemmap.h.

Constructor & Destructor Documentation

◆ QgsLayoutItemMap()

QgsLayoutItemMap::QgsLayoutItemMap ( QgsLayout * layout )

Definition at line 75 of file qgslayoutitemmap.cpp.

◆ atlasDriven()

bool QgsLayoutItemMap::atlasDriven ( ) const

inline

Returns whether the map extent is set to follow the current atlas feature.

Returns: true if map will follow the current atlas feature.

See also: setAtlasDriven; atlasScalingMode

Definition at line 319 of file qgslayoutitemmap.h.

◆ atlasMargin()

double QgsLayoutItemMap::atlasMargin ( QgsLayoutObject::PropertyValueType valueType = QgsLayoutObject::EvaluatedValue )

Returns the margin size (percentage) used when the map is in atlas mode.

Parameters

valueType controls whether the returned value is the user specified atlas margin, or the current evaluated atlas margin (which may be affected by data driven atlas margin settings).

Returns: margin size in percentage to leave around the atlas feature's extent

Note: this is only used if atlasScalingMode() is Auto.

See also: atlasScalingMode; setAtlasMargin

Definition at line 455 of file qgslayoutitemmap.cpp.

◆ atlasScalingMode()

AtlasScalingMode QgsLayoutItemMap::atlasScalingMode ( ) const

inline

Returns the current atlas scaling mode.

This controls how the map's extents are calculated for the current atlas feature when an atlas composition is enabled.

Returns: the current scaling mode

Note: this parameter is only used if atlasDriven() is true

See also: setAtlasScalingMode; atlasDriven

Definition at line 338 of file qgslayoutitemmap.h.

◆ boundingRect()

QRectF QgsLayoutItemMap::boundingRect ( ) const

overrideprotected

Definition at line 1128 of file qgslayoutitemmap.cpp.

◆ containsAdvancedEffects()

bool QgsLayoutItemMap::containsAdvancedEffects ( ) const

overridevirtual

Returns true if the item contains contents with blend modes or transparency effects which can only be reproduced by rastering the item.

Subclasses should ensure that implemented overrides of this method also check the base class result.

static

Returns a new map item for the specified layout.

The caller takes responsibility for deleting the returned object.

Definition at line 113 of file qgslayoutitemmap.cpp.

◆ createExpressionContext()

QgsExpressionContext QgsLayoutItemMap::createExpressionContext ( ) const

overridevirtual

This method needs to be reimplemented in all classes which implement this interface and return an expression context.

Since: QGIS 3.0

Reimplemented from QgsLayoutItem.

Definition at line 1133 of file qgslayoutitemmap.cpp.

◆ crs()

QgsCoordinateReferenceSystem QgsLayoutItemMap::crs ( ) const

Returns coordinate reference system used for rendering the map.

This will match the presetCrs() if that is set, or if a preset CRS is not set then the map's CRS will follow the composition's project's CRS.

See also: presetCrs(); setCrs()

Definition at line 247 of file qgslayoutitemmap.cpp.

◆ displayName()

QString QgsLayoutItemMap::displayName ( ) const

overridevirtual

Gets item display name.

This is the item's id if set, and if not, a user-friendly string identifying item type.

See also: id(); setId()

Reimplemented from QgsLayoutItem.

Definition at line 103 of file qgslayoutitemmap.cpp.

◆ draw()

void QgsLayoutItemMap::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 500 of file qgslayoutitemmap.cpp.

◆ drawAnnotations()

bool QgsLayoutItemMap::drawAnnotations ( ) const

inline

See also: setExtent(); extent()

◆ finalizeRestoreFromXml()

void QgsLayoutItemMap::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.

◆ followVisibilityPreset()

bool QgsLayoutItemMap::followVisibilityPreset ( ) const

inline

Returns whether the map should follow a map theme.

If true, the layers and layer styles will be used from given preset name (configured with setFollowVisibilityPresetName() method). This means when preset's settings are changed, the new settings are automatically picked up next time when rendering, without having to explicitly update them. At most one of the flags keepLayerSet() and followVisibilityPreset() should be enabled at any time since they are alternative approaches - if both are enabled, following map theme has higher priority. If neither is enabled (or if preset name is not set), map will use the same configuration as the map canvas uses.

Definition at line 250 of file qgslayoutitemmap.h.

◆ followVisibilityPresetName()

QString QgsLayoutItemMap::followVisibilityPresetName ( ) const

inline

Preset name that decides which layers and layer styles are used for map rendering.

inline

Returns whether a stored layer set should be used or the current layer set from the project associated with the layout.

If includeLayerSettings is true, than settings specifically relating to map layers and map layer styles will be calculated.

◆ readPropertiesFromElement()

bool QgsLayoutItemMap::readPropertiesFromElement	(	const QDomElement &	element,

		const QgsReadWriteContext &	context
	)

overrideprotectedvirtual

Sets item state from a DOM element.

Parameters

element	is the DOM element for the item
