About Kirigami API documentation: use https://api-staging.kde.org/kirigami-index.html for now

We are aware of issues involving broken links to Kirigami API documentation. We are currently working on a better website to address these issues, porting the API docs where possible.

In its current state, the staging API website under development for Kirigami can be used to access all relevant Kirigami API pages, and it should already work better than the previous API website. You can access the staging API website through https://api-staging.kde.org/kirigami-index.html.

If you'd like to assist us in our efforts to port the API documentation, take a look at our Port API documentation to QDoc metatask.

Se la tua applicazione fa qualcosa che impiega una notevole quantità di tempo, vorrai utilizzare un elemento visivo che dice all'utente che sta succedendo qualcosa dietro le quinte.

I controlli di QtQuick forniscono due utili componenti che puoi usare a questo scopo.

Barra di avanzamento

Controls.ProgressBar is a component that lets you easily include progress bars in your application. There are four main properties you will need to use:

from: the minimum value represented by the start of the progress bar
to: the maximum value represented by the end of the progress bar
value: the current value of the action that is in progress (e.g. 50% loaded)
indeterminate: if the action that is in process currently has no clear progress value, you can set this property to true to show the user that something is happening but its progress is not yet clear (but will be soon).

import QtQuick
import QtQuick.Layouts
import QtQuick.Controls as Controls
import org.kde.kirigami as Kirigami

Kirigami.ApplicationWindow {
    title: "Progressbar App"
    width: 400
    height: 400
    pageStack.initialPage: Kirigami.Page {
        ColumnLayout {
            anchors.left: parent.left
            anchors.right: parent.right
            Controls.ProgressBar {
                Layout.fillWidth: true
                from: 0
                to: 100
                value: 50
                indeterminate: false
            }
            Controls.ProgressBar {
                Layout.fillWidth: true
                from: 0
                to: 100
                // valore: 50
                indeterminate: true
            }
        }
    }
}

Indicatore di occupato

In cases where loading times are shorter or measuring progress is not feasible, you can instead use Controls.BusyIndicator. This component provides a simple spinning wheel that shows users that something is happening.

If you want the indicator to stop running, you can do so by setting the running property to false, in which case the .

import QtQuick
import QtQuick.Controls as Controls
import org.kde.kirigami as Kirigami

Kirigami.ApplicationWindow {
    title: "Progressbar App"
    width: 400
    height: 400
    pageStack.initialPage: Kirigami.Page {
        actions: [
            Kirigami.Action {
                text: "Toggle busy indicator"
                onTriggered: indicator.running ? indicator.running = false : indicator.running = true
            }
        ]
        Controls.BusyIndicator {
            id: indicator
            anchors.centerIn: parent
        }
    }
}
