QML Elements

These are the functionally grouped lists of QML elements as part of Qt Quick.

Elements are declared with the their name and two curly braces. Elements may be nested in elements, thereby creating a parent-child relationship between the two elements.

To see the QML elements listed by functional area, see the Groups Of Related QML Elements page.

Basic QML Elements

Item - Basic item element inherited by QML elements
Component - Encapsulates QML elements during importing
QtObject - Basic element containing only the objectName property

Graphics

Rectangle - A rectangle element
Image - For incorporating bitmaps into a scene
BorderImage - Allows the use of images as borders
AnimatedImage - For playing animations stored in a series of frames
Gradient - For defining a color gradient
GradientStop - Used to define a color within a Gradient
SystemPalette - Provides access to the Qt palettes

Text Handling

Text - For inserting formatted text into a scene
TextInput - Captures user key input
TextEdit - Displays multiple lines of editable formatted text
IntValidator - Validates values as integers
DoubleValidator - Validates real values
RegExpValidator - Validator for string regular expressions
FontLoader - Loads fonts by name or URL

Mouse and Interaction Area

MouseArea - Sets up an area for mouse interaction
Keys - Provides components with attached properties to handle key input.
FocusScope - Element that mediate keyboard focus changes
Flickable - Provides a surface that can be "flicked"
Flipable - Provides a surface that produces "flipping" effects
PinchArea - Enables simple pinch gesture handling

Positioners and Repeater

Column - Arranges its children vertically
Row - Arranges its children horizontally
Grid - Positions its children in a grid
Flow - Positions its children with wrapping support
Repeater - Uses a model to create multiple components

Transformations

Scale - Assigns item scaling behaviors
Rotation - Assigns item rotation behaviors
Translate - Assigns item translation behaviors

States

State - Defines sets of configurations of objects and properties
PropertyChanges - Describes property changes within a state
StateGroup - Contains a set of states and state transitions
StateChangeScript - Allows script binding in a state
ParentChange - Re-parent an Item in a state change
AnchorChanges - Change the anchors of an item in a state

Animation and Transitions

Transition - Animates transitions during state changes
SequentialAnimation - Runs animations sequentially
ParallelAnimation - Runs animations in parallel
Behavior - Specifies a default animation for property changes
PropertyAction - Sets immediate property changes during animation
PauseAnimation - Introduces a pause in an animation
SmoothedAnimation - Allows a property to smoothly track a value
SpringAnimation - Allows a property to track a value in a spring-like motion
ScriptAction - Runs scripts during an animation

Elements that animate properties based on data types

PropertyAnimation - Animates property changes
NumberAnimation - Animates properties of type qreal
Vector3dAnimation - Animates properties of type QVector3d
ColorAnimation - Animates color changes
RotationAnimation - Animates rotations
ParentAnimation - Animates parent changes
AnchorAnimation - Animates anchor changes

Models and Data Handling

ListModel - Defines a list of data
ListElement - Defines a data item in a ListModel
VisualItemModel - Contains items that already defines its own visual delegate
VisualDataModel - Encapsulates a model and a delegate
XmlListModel - Specifies a model using XPath expressions
XmlRole - Specifies a role for an XmlListModel
Binding - Binds any value to any property
Package - Collection that enables sharing of items within different views

Views

ListView - Provides a list visualization of a model
GridView - Provides a grid visualization of a model
PathView - Visualizes a model's contents along a path. See Path Elements for more information.

Path Definition

Path - Defines a path used by PathView
PathLine - Defines a line in Path
PathQuad - Defines a quadratic Bezier curve in a Path
PathCubic - Defines a cubic Bezier curve in a Path
PathAttribute - Allows the setting of attributes along a Path
PathPercent - Modifies the item distribution along a Path

Utility

Connections - Explicitly connects signals and signal handlers
Timer - Provides timed triggers
Qt - The QML global Qt object provides useful enums and functions from Qt.
WorkerScript - Enables the use of threads in QML
Loader - Controls the loading of items or components
LayoutItem - Allows declarative UI elements inside Qt's Graphics View layouts

Graphical Effects

Particles - Generates and animates particles
ParticleMotionLinear - Adds linear motion behavior to Particles
ParticleMotionGravity - Adds gravitational motion to Particles
ParticleMotionWander - Adds varied motions to Particles
ShaderEffectItem - Enables the use of OpenGL Shading Language together with QML
ShaderEffectSource - Encapsulates QML item tree as a source item for ShaderEffectItem

Add-On Elements

These elements are not included in the QtQuick 1.0 module. Their respective QML bindings should first be obtained and installed.

QtWebKit QML Module - WebView Element - For displaying Web contents
Mobility QML Plugins
Qt Quick Components
