The StackLayout class provides a stack of items where only one item is visible at a time. More...
| Import Statement: | import QtQuick.Layouts 1.11 |
| Inherits: |
The current visible item can be modified by setting the currentIndex property. The index corresponds to the order of the StackLayout's children.
In contrast to most other layouts, child Items' Layout.fillWidth and Layout.fillHeight properties default to true. As a consequence, child items are by default filled to match the size of the StackLayout as long as their Layout.maximumWidth or Layout.maximumHeight does not prevent it.
Items are added to the layout by reparenting the item to the layout. Similarly, removal is done by reparenting the item from the layout. Both of these operations will affect the layout's count property.
The following code will create a StackLayout where only the 'plum' rectangle is visible.
StackLayout {
id: layout
anchors.fill: parent
currentIndex: 1
Rectangle {
color: 'teal'
implicitWidth: 200
implicitHeight: 200
}
Rectangle {
color: 'plum'
implicitWidth: 300
implicitHeight: 200
}
}
Items in a StackLayout support these attached properties:

See also ColumnLayout, GridLayout, RowLayout, and StackView.
|
count : int |
This property holds the number of items that belong to the layout.
Only items that are children of the StackLayout will be candidates for layouting.
|
currentIndex : int |
This property holds the index of the child item that is currently visible in the StackLayout. By default it will be -1 for an empty layout, otherwise the
default is 0 (referring to the first item).
