Páginas desplazables y vistas de lista
Kirigami.ScrollablePage
A Kirigami.ScrollablePage is a page that holds scrollable content, such as a ListView . Scrolling, as well as scrolling indicators, are automatically managed.
Kirigami.ScrollablePage {
id: root
// El rectángulo se podrá desplazar automáticamente
Rectangle {
width: root.width
height: 99999
}
}
En casi todos los demás aspectos, una página desplazable es lo mismo que una página normal.
Advertencia
Do not put a ScrollView inside of a Kirigami.ScrollablePage ; children of aKirigami.ScrollablePage
are already inside a ScrollView
.ListView en una ScrollablePage
When the direct children of a Kirigami.ScrollablePage extend vertically beyond the size of the page itself, a scrollbar appears at the right edge of the page and the page will be scrollable.

Often you have more than one child in your Kirigami.ScrollablePage , and positioning items can be tricky—especially in combination with a ListView .
- For non-visual components, having them inside the ListView component won't change the visuals of the page, so we can move them inside the scope of the list view. Same for elements anchored to the center of the page, such as placeholder messages for empty list views.
- For other items, it might make sense to move them to the header or footer of the Kirigami.ScrollablePage . This is often the case for search bars.
PlaceholderMessage
It is possible to add a Kirigami.PlaceholderMessage with some instructions in case the list view is empty.
Kirigami.ScrollablePage {
ListView {
id: listView
Kirigami.PlaceholderMessage {
anchors.centerIn: parent
width: parent.width - (Kirigami.Units.largeSpacing * 4)
visible: listView.count === 0
text: i18n("No data found")
helpfulAction: Kirigami.Action {
text: i18n("Load data")
...
}
}
model: ...
}
}
Buscar en la ListView
A search field is often added to a Kirigami.ScrollablePage to filter the ListView . This can be done by changing the default titleDelegate to use a Kirigami.SearchField instead.
Kirigami.ScrollablePage {
titleDelegate: Kirigami.SearchField {
Layout.topMargin: Kirigami.Units.smallSpacing
Layout.bottomMargin: Kirigami.Units.smallSpacing
Layout.fillHeight: true
Layout.fillWidth: true
onTextChanged: mySortFilterModel.filterText = text
KeyNavigation.tab: listView
}
ListView {
id: listView
...
}
}
Sugerencia
You can use KSortFilterProxyModel from KItemModel to easily add filtering capability directly in QML without any need for C++ code.Tirar para actualizar
Another function provided by this component is a "pull-to-refresh" action. To use this, activate it as follows:
Kirigami.ScrollablePage {
id: view
supportsRefreshing: true
onRefreshingChanged: {
if (refreshing) {
myModel.refresh();
}
}
ListView {
// NOTE: MyModel doesn't come from the components, it's purely an example on how it can be
// used together with some application logic that can update the list model and signals when
// it's done.
model: MyModel {
onRefreshDone: view.refreshing = false;
}
delegate: BasicListItem {}
}
}
Al tirar hacia abajo, también puede activar un modo especial con un margen superior más grande que facilita el uso de la aplicación con una sola mano.
