Tarjetas
Los tipos de Kirigami AbstractCard y Card se usan para implementar el popular componente de tarjeta que se usa en muchas plataformas móviles y web. Las tarjetas se pueden usar para mostrar una recopilación de información o acciones de una forma atractiva y distintiva.
Kirigami también ofrece tres tipos de vistas y posicionadores para ayudarle a presentar tarjetas con diseños agradables y receptivos.
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
}
]
}
}
