Tarjetas

Una tarjeta sirve como resumen, es un punto de entrada para obtener información más detallada y puede ofrecer acceso directo a las acciones más importantes de un elemento.

The Kirigami types AbstractCard and Card are used to implement the popular card component used on many mobile and web platforms. Cards can be used to display a collection of information or actions in an attractive and distinctive way.

Kirigami also offers 3 kinds of views and positioners to aid you in presenting your cards with beautiful and responsive layouts.

AbstractCard

A Kirigami.AbstractCard is the simplest type of card. It's just a rectangle with a shadow, which can contain any Item in it. It can also have Items assigned to its header or footer properties. In this case a Kirigami.Heading is its header and a Controls.Label is the card's contentItem .

Kirigami.AbstractCard {
    Layout.fillHeight: true
    header: Kirigami.Heading {
        text: qsTr("AbstractCard")
        level: 2
    }
    contentItem: Controls.Label {
        wrapMode: Text.WordWrap
        text: "..."
    }
}

Card

A Kirigami.Card inherits from AbstractCard and provides more features out of the box. Cards inherit the same header and footer from an Abstract Card, but you are encouraged to use a banner and a set of Kirigami.Action in the actions group instead.

Kirigami.Card {
    actions: [
        Kirigami.Action {
            text: qsTr("Action1")
            icon.name: "add-placemark"
        },
        Kirigami.Action {
            text: qsTr("Action2")
            icon.name: "address-book-new-symbolic"
        },
        // ...
    ]
    banner {
        source: "../banner.jpg"
        title: "Title Alignment"
        // El título se puede situar en el *banner*
        titleAlignment: Qt.AlignLeft | Qt.AlignBottom
    }
    contentItem: Controls.Label {
        wrapMode: Text.WordWrap
        text: "My Text"
    }
}

CardsLayout

A Kirigami.CardsLayout is most useful when the cards being presented are either not instantiated by a model or are instantiated by a model that always has very few items. They are presented as a grid of two columns which will remain centered if the application is really wide, or become a single column if there is not enough space for two columns, such as a mobile phone screen.

A card can optionally be oriented horizontally. In this case it will be wider than tall, and is better suited to being placed in a ColumnLayout. If you must put it in a CardsLayout , it will have a maximumColumns of 2 by default.

ColumnLayout {
    Kirigami.CardsLayout {
        Kirigami.Card {
            contentItem: Controls.Label {
                wrapMode: Text.WordWrap
                text: "My Text2"
            }
        }
        Kirigami.AbstractCard { 
            contentItem: Controls.Label {
                wrapMode: Text.WordWrap
                text: "My Text"
            }
        }
        Kirigami.Card {
            headerOrientation: Qt.Horizontal
            contentItem: Controls.Label {
                wrapMode: Text.WordWrap
                text: "My Text2"
            }
        }
    }
}

CardsListView

Una Kirigami.CardsListView es una vista de lista que se puede usar con componentes AbstractCard .

A CardsListView will stretch child cards to its own width. This component should therefore only be used with cards which will look good at any horizontal size. Use of a Card component inside it is discouraged, unless it has Qt.Horizontal as its headerOrientation property.

The choice between using this view with AbstractCard components or a conventional ListView with AbstractListItem / BasicListItem components is purely an aesthetic one.

Kirigami.CardsListView {
    id: view
    model: 100

    delegate: Kirigami.AbstractCard {
        // NOTA: no usar nunca un Layout como contentItem, ya que puede provocar bucles de enlace.
        contentItem: Item {
            implicitWidth: delegateLayout.implicitWidth
            implicitHeight: delegateLayout.implicitHeight
            GridLayout {
                id: delegateLayout
                anchors {
                    left: parent.left
                    top: parent.top
                    right: parent.right
                    // IMPORTANTE: no colocar nunca el margen inferior
                }
                rowSpacing: Kirigami.Units.largeSpacing
                columnSpacing: Kirigami.Units.largeSpacing
                columns: width > Kirigami.Units.gridUnit * 20 ? 4 : 2
                Kirigami.Icon {
                    source: "applications-graphics"
                    Layout.fillHeight: true
                    Layout.maximumHeight: Kirigami.Units.iconSizes.huge
                    Layout.preferredWidth: height
                }
                Kirigami.Heading {
                    level: 2
                    text: qsTr("Product ")+ modelData
                }
                Controls.Button {
                    Layout.alignment: Qt.AlignRight
                    Layout.columnSpan: 2 
                    text: qsTr("Install")
                }
            }
        }
    }
}

CardsGridView

Use un Kirigami.CardsGridView para mostrar tarjetas en una cuadrícula.

Its behavior is the same as a CardsLayout , and it allows cards to be put in one or two columns depending on the available width.

CardsGridView has the limitation that every card must have the same exact height, so cellHeight must be manually set to a value for which the content must fit for every child card.

If possible use CardsGridView only when you need to instantiate many cards. If you are only going to instantiate a few cards, opt for a CardsLayout with a Repeater instead.

Kirigami.CardsGridView {
    id: view
    model: ListModel {
        id: mainModel
        // Modelo con los siguientes roles: texto, acciones e imagen
    }
    delegate:Kirigami.Card {
        id: card
        banner {
            title: model.title
            source: model.image
        }
        contentItem: Controls.Label {
            wrapMode: Text.WordWrap
            text: model.text
        }
        actions: [
            Kirigami.Action {
                text: model.actions.get(0).text
                icon.name: model.actions.get(0).icon
            },
            Kirigami.Action {
                text: model.actions.get(1).text
                icon.name: model.actions.get(1).icon
            }
        ]
    }
}
