addCalloutType()

bool QgsCalloutRegistry::addCalloutType

(

QgsCalloutAbstractMetadata *

metadata

)

Registers a new callout type.

Ownership of metadata is transferred to the registry.

Definition at line 63 of file qgscalloutsregistry.cpp.

calloutMetadata()

QgsCalloutAbstractMetadata * QgsCalloutRegistry::calloutMetadata

(

const QString &

type

)

const

Returns the metadata for specified the specified callout type.

Returns nullptr if no matching callout style was found.

Definition at line 83 of file qgscalloutsregistry.cpp.

calloutTypes()

QStringList QgsCalloutRegistry::calloutTypes

(

)

const

Returns a list of all available callout types.

Definition at line 78 of file qgscalloutsregistry.cpp.

createCallout() [1/2]

QgsCallout * QgsCalloutRegistry::createCallout	(	const QString &	type,
		const QDomElement &	element,
		const QgsReadWriteContext &	context
	)		const

Creates a new instance of a callout of the specified type, using the properties from a DOM element.

The caller takes ownership of the callout.

Definition at line 72 of file qgscalloutsregistry.cpp.

createCallout() [2/2]

QgsCallout * QgsCalloutRegistry::createCallout	(	const QString &	type,
		const QVariantMap &	properties = QVariantMap(),
		const QgsReadWriteContext &	context = QgsReadWriteContext()
	)		const

Creates a new instance of a callout, given the callout type and properties.

The caller takes ownership of the callout.

Definition at line 93 of file qgscalloutsregistry.cpp.

defaultCallout()

QgsCallout * QgsCalloutRegistry::defaultCallout ( )

static

Create a new instance of a callout with default settings.

The caller takes ownership of the callout.

Definition at line 88 of file qgscalloutsregistry.cpp.
