Klarigante paĝojn

Nia apo

En la antaŭa lernilo, ni sukcesis agordi, konstrui kaj kompili nian unuan Kirigami-aplikaĵon. Kun la bazaĵoj en la loko, ni povas komenci nian vojaĝon al kreado de plene prezentita aplikaĵo.

Ĉi tiuj lerniloj koncentriĝos pri kreado de aplikaĵo, kiu ebligas al la uzanto vidi kiom da tagoj restas ĝis evento de ilia elekto.

Ni ankaŭ rekomendas vin kontroli la Kirigami Gallery, kiu provizas kelkajn utilajn UI-ekzemplojn.

En ĉi tiu sekcio ni koncentriĝos pri paĝoj, unu el la ŝlosilaj strukturaj elementoj de iu ajn Kirigami-apliko.

Paĝoj

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.

Ni reiru al la dosiero Main.qml, kiun ni kreis en nia antaŭa lernilo:

// 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.

pageStack.initialPage: Qt.resolvedUrl("StartPage.qml")
