- \qmltype Container
- \inherits Control
-//! \instantiates QQuickContainer
- \inqmlmodule QtQuick.Controls
- \since 5.7
- \ingroup qtquickcontrols2-containers
- \brief Abstract base type providing functionality common to containers.
-
- Container is the base type of container-like user interface controls that
- allow dynamic insertion and removal of items.
-
- \section2 Using Containers
-
- Typically, items are statically declared as children of Container, but it
- is also possible to \l {addItem}{add}, \l {insertItem}{insert},
- \l {moveItem}{move} and \l {removeItem}{remove} items dynamically. The
- items in a container can be accessed using \l itemAt() or
- \l contentChildren.
-
- Most containers have the concept of a "current" item. The current item is
- specified via the \l currentIndex property, and can be accessed using the
- read-only \l currentItem property.
-
- The following example illustrates dynamic insertion of items to a \l TabBar,
- which is one of the concrete implementations of Container.
-
- \code
- Row {
- TabBar {
- id: tabBar
-
- currentIndex: 0
- width: parent.width - addButton.width
-
- TabButton { text: "TabButton" }
- }
-
- Component {
- id: tabButton
- TabButton { text: "TabButton" }
- }
-
- Button {
- id: addButton
- text: "+"
- flat: true
- onClicked: {
- tabBar.addItem(tabButton.createObject(tabBar))
- console.log("added:", tabBar.itemAt(tabBar.count - 1))
- }
- }
- }
- \endcode
-
- \section2 Managing the Current Index
-
- When using multiple containers, such as \l TabBar and \l SwipeView, together,
- their \l currentIndex properties can be bound to each other to keep them in
- sync. When the user interacts with either container, its current index changes
- automatically propagate to the other container.
-
- Notice, however, that assigning a \c currentIndex value in JavaScript removes
- the respective binding. In order to retain the bindings, use the following
- methods to alter the current index:
-
- \list
- \li \l incrementCurrentIndex()
- \li \l decrementCurrentIndex()
- \li \l setCurrentIndex()
- \endlist
-
- \code
- TabBar {
- id: tabBar
- currentIndex: swipeView.currentIndex
- }
-
- SwipeView {
- id: swipeView
- currentIndex: tabBar.currentIndex
- }
-
- Button {
- text: qsTr("Home")
- onClicked: swipeView.setCurrentIndex(0)
- enabled: swipeView.currentIndex != 0
- }
-
- Button {
- text: qsTr("Previous")
- onClicked: swipeView.decrementCurrentIndex()
- enabled: swipeView.currentIndex > 0
- }
-
- Button {
- text: qsTr("Next")
- onClicked: swipeView.incrementCurrentIndex()
- enabled: swipeView.currentIndex < swipeView.count - 1
- }
- \endcode
-
-
- \section2 Implementing Containers
-
- Container does not provide any default visualization. It is used to implement
- such containers as \l SwipeView and \l TabBar. When implementing a custom
- container, the most important part of the API is \l contentModel, which provides
- the contained items in a way that it can be used as a delegate model for item
- views and repeaters.
-
- \code
- Container {
- id: container
-
- contentItem: ListView {
- model: container.contentModel
- snapMode: ListView.SnapOneItem
- orientation: ListView.Horizontal
- }
-
- Text {
- text: "Page 1"
- width: container.width
- height: container.height
- }
-
- Text {
- text: "Page 2"
- width: container.width
- height: container.height
- }
- }
- \endcode
-
- Notice how the sizes of the page items are set by hand. This is because the
- example uses a plain Container, which does not make any assumptions on the
- visual layout. It is typically not necessary to specify sizes for items in
- concrete Container implementations, such as \l SwipeView and \l TabBar.
