Explaining pages
Pages allow you to organize your application content
In the previous tutorial, we managed to set up, build, and compile our first Kirigami application. With the basics in place, we can begin our journey towards creating a fully-featured application.
These tutorials will focus on creating an application that lets the user see how many days are left until an event of their choice.
We also recommend you check out the Kirigami Gallery, which provides a number of useful UI examples.
In this section we'll be focusing on pages, one of the key structural elements of any Kirigami application.
Pages
Kirigami apps are typically organized in pages by using Kirigami.Page. Pages are the different "screens" of an app. You will want to have a page dedicated to specific aspects of your app's interaction, and to make things easier you can create different QML files for each page.
Pages are organized in a page stack where they can be pushed and popped. On a phone only the top-most page is shown, whereas on a larger screen (desktop or tablet), if desired, multiple pages can be shown next to each other.


Let's go back to the Main.qml
file we created in our previous tutorial:
// Includes relevant modules used by the QML
import QtQuick
import QtQuick.Layouts
import QtQuick.Controls as Controls
import org.kde.kirigami as Kirigami
// Provides basic features needed for all kirigami applications
Kirigami.ApplicationWindow {
// Unique identifier to reference this object
id: root
width: 400
height: 300
// Window title
// i18nc() makes a string translatable
// and provides additional context for the translators
title: i18nc("@title:window", "Hello World")
// Set the first page that will be loaded when the app opens
// This can also be set to an id of a Kirigami.Page
pageStack.initialPage: Kirigami.Page {
Controls.Label {
// Center label horizontally and vertically within parent object
anchors.centerIn: parent
text: i18n("Hello World!")
}
}
}
We make our application start to our Kirigami.Page. All we have included in it is a label containing "Hello World", but we're going to spruce things up a little.
The idea behind our app is that we're going to be able to display a bunch of countdowns to the user. The problem with a normal Kirigami.Page is that it has a fixed vertical size, so instead we can use a Kirigami.ScrollablePage, which already comes with its own built-in scrollbar.
import QtQuick
import QtQuick.Layouts
import QtQuick.Controls as Controls
import org.kde.kirigami as Kirigami
Kirigami.ApplicationWindow {
id: root
width: 400
height: 300
title: i18nc("@title:window", "Day Kountdown")
pageStack.initialPage: Kirigami.ScrollablePage {
title: i18nc("@title", "Kountdown")
}
}
Kirigami pages also feature neat titles placed within the toolbar, quickly indicating to the user which page they are on. All we need to do is to set a page title using the title
property of Kirigami.ScrollablePage. In this case, we used one of the i18nc()
functions we explored in our previous tutorial to this end.
