Detailed Description

An object that instantiates an entire QML context, with its own declarative engine.

Author: Marco Martin [email protected][email protected]kde.[email protected]org

KDeclarative::QmlObject provides a class to conveniently use QML based declarative user interfaces inside Plasma widgets. A QmlObject corresponds to one QML file (which can include others). It will have its own QQmlEngine with a single root object, described in the QML file.

Constructor & Destructor Documentation

◆ QmlObject() [1/5]

KDeclarative::QmlObject::QmlObject ( QObject * parent = nullptr )

explicit

Constructs a new QmlObject.

Parameters

parent the parent of this object

Definition at line 134 of file qmlobject.cpp.

◆ QmlObject() [2/5]

KDeclarative::QmlObject::QmlObject	(	QQmlEngine *	engine,
		QObject *	parent = `nullptr`
	)

explicit

Constructs a new QmlObject.

Parameters

engine	a QQmlEngine we want to use
parent	the parent of this object

Deprecated:: Since 5.95, Use QmlObject(std::shared_ptr<QmlEngine>, QObject*) instead.

Definition at line 140 of file qmlobject.cpp.

◆ QmlObject() [3/5]

KDeclarative::QmlObject::QmlObject	(	QQmlEngine *	engine,
		QQmlContext *	rootContext,
		QObject *	parent = `nullptr`
	)

explicit

Constructs a new QmlObject.

Parameters

engine	the QQmlEngine to use
rootContext	the root context to use for object creation
parent	the parent of this object

Deprecated:: Since 5.95, Use QmlObject(std::shared_ptr<QmlEngine>, QmlContext*, QObject*) instead.

Definition at line 145 of file qmlobject.cpp.

◆ QmlObject() [4/5]

KDeclarative::QmlObject::QmlObject	(	std::shared_ptr< QQmlEngine >	engine,
		QQmlContext *	rootContext = `nullptr`,
		QObject *	parent = `nullptr`
	)

explicit

Construct a new QmlObject.

Parameters

engine	The QQmlEngine to use. If this object is the first user of the engine (e.g. use_count() is 1), KDeclarative::setupEngine() will be called. If this is nullptr, a new engine will be created for this object to use.
rootContext	The QML context to use for object creation. If this is nullptr, the engine's root context will be used.
parent	The QObject parent for this object.

Definition at line 157 of file qmlobject.cpp.

◆ QmlObject() [5/5]

KDeclarative::QmlObject::QmlObject	(	QQmlEngine *	engine,
		QQmlContext *	rootContext,
		QmlObject *	obj,
		QObject *	parent = `nullptr`
	)

explicitprotected

Constructs a new QmlObject.

Parameters

engine	a QQmlEngine we want to use
rootContext	the root context we want to use for objects creation
obj	setupEngine is called when this is set to nullptr. This way the creator can influence if the engine should be initialized or not in case it is shared between multiple objects (such as QmlObjectSharedEngine)
parent	the parent of this object

Since: 5.45

Deprecated:: Since 5.95, Use QmlObject(std::shared_ptr<QmlEngine>, QmlContext*, QObject*) instead. The "obj" parameter has been dropped, instead setupEngine will be called if this QmlObject is the first user of the engine.

Member Function Documentation

◆ completeInitialization

void KDeclarative::QmlObject::completeInitialization ( const QVariantHash & initialProperties = QVariantHash() )

slot

Finishes the process of initialization.

If isInitializationDelayed() is false, calling this will have no effect.

Parameters

initialProperties optional properties that will be set on the object when created (and before Component.onCompleted gets emitted

Definition at line 296 of file qmlobject.cpp.

◆ createObjectFromComponent()

QObject * KDeclarative::QmlObject::createObjectFromComponent	(	QQmlComponent *	component,
		QQmlContext *	context = `nullptr`,
		const QVariantHash &	initialProperties = `QVariantHash()`
	)

Creates and returns an object based on the provided QQmlComponent with the same QQmlEngine and the same root context as the admin object, that will be the parent of the newly created object.

Parameters

component	the component we want to instantiate
context	The QQmlContext in which we will create the object, if 0 it will use the engine's root context
initialProperties	optional properties that will be set on the object when created (and before Component.onCompleted gets emitted

Definition at line 336 of file qmlobject.cpp.

◆ createObjectFromSource()

QObject * KDeclarative::QmlObject::createObjectFromSource	(	const QUrl &	source,
		QQmlContext *	context = `nullptr`,
		const QVariantHash &	initialProperties = `QVariantHash()`
	)

Creates and returns an object based on the provided url to a Qml file with the same QQmlEngine and the same root context as the main object, that will be the parent of the newly created object.

Parameters

source	url where the QML file is located
context	The QQmlContext in which we will create the object, if 0 it will use the engine's root context
initialProperties	optional properties that will be set on the object when created (and before Component.onCompleted gets emitted

Definition at line 328 of file qmlobject.cpp.

◆ engine()

QQmlEngine * KDeclarative::QmlObject::engine ( )

Returns: the declarative engine that runs the qml file assigned to this widget.

Definition at line 245 of file qmlobject.cpp.

◆ finished

void KDeclarative::QmlObject::finished ( )

signal

Emitted when the parsing and execution of the QML file is terminated.

◆ isInitializationDelayed()

bool KDeclarative::QmlObject::isInitializationDelayed ( ) const

Returns: true if the initialization of the QML file will be delayed at the end of the event loop

Definition at line 240 of file qmlobject.cpp.

◆ loadPackage()

void KDeclarative::QmlObject::loadPackage ( const QString & packageName )

Load the package called packageName, then loads the mainscript file for that package.

Parameters

packageName the plugin name of the package

Definition at line 217 of file qmlobject.cpp.

◆ mainComponent()

QQmlComponent * KDeclarative::QmlObject::mainComponent ( ) const

Returns: the main QQmlComponent of the engine

Definition at line 259 of file qmlobject.cpp.

◆ package()

KPackage::Package KDeclarative::QmlObject::package ( ) const

Returns: the optional package, if any

Definition at line 230 of file qmlobject.cpp.

◆ rootContext()

QQmlContext * KDeclarative::QmlObject::rootContext ( ) const

The components's creation context.

Since: 5.11

Definition at line 264 of file qmlobject.cpp.

◆ rootObject()

QObject* KDeclarative::QmlObject::rootObject ( ) const

Returns: the root object of the declarative object tree

◆ setInitializationDelayed()

void KDeclarative::QmlObject::setInitializationDelayed ( const bool delay )

Sets whether the execution of the QML file has to be delayed later in the event loop.

It has to be called before setQmlPath(). In this case it will be possible to assign new objects in the main engine context before the main component gets initialized. In that case it will be possible to access it immediately from the QML code. The initialization will either be completed automatically asynchronously or explicitly by calling completeInitialization()

Parameters

delay if true the initialization of the QML file will be delayed at the end of the event loop

Definition at line 235 of file qmlobject.cpp.

◆ setPackage()

void KDeclarative::QmlObject::setPackage ( const KPackage::Package & package )

Sets a package, then loads the mainscript file for that package.

Parameters

package the package we want to use to provide QML files to this QML object

Definition at line 224 of file qmlobject.cpp.

◆ setSource()

void KDeclarative::QmlObject::setSource ( const QUrl & source )

Sets the path of the QML file to parse and execute.

Parameters

path	the absolute path of a QML file

Definition at line 206 of file qmlobject.cpp.

◆ setTranslationDomain()

void KDeclarative::QmlObject::setTranslationDomain ( const QString & translationDomain )

Call this method before calling setupBindings to install a translation domain for all i18n global functions.

If a translation domain is set all i18n calls delegate to the matching i18nd calls with the provided translation domain.

The translationDomain affects all i18n calls including those from imports. Because of that modules intended to be used as imports should prefer the i18nd variants and set the translation domain explicitly in each call.

This method is only required if your declarative usage is inside a library. If it's in an application there is no need to set the translation domain as the application's domain can be used.

Parameters

translationDomain The translation domain to be used for i18n calls.

Since: 5.0

Definition at line 196 of file qmlobject.cpp.

◆ source()

QUrl KDeclarative::QmlObject::source ( ) const

Returns: the absolute path of the current QML file

◆ status()

QQmlComponent::Status KDeclarative::QmlObject::status ( ) const

The component's current status.

Since: 5.11

◆ translationDomain()

QString KDeclarative::QmlObject::translationDomain ( ) const

Returns: the translation domain for the i18n calls done in this QML engine

Since: 5.0
