W poprzednim samouczku, udało nam się utworzyć oraz zbudować naszą pierwszą aplikację Kirigami. Posiadając podstawy, możemy rozpocząć naszą przygodę z tworzeniem pełnowartościowych aplikacji.
These tutorials will focus on creating an application that lets the user see how many days are left until an event of their choice. That doesn't mean you shouldn't deviate and try to create your own thing! Just make sure you pay close attention to how things work first, so that you can adjust when things are different in your own code. We also recommend you check out the Kirigami Gallery, which provides a number of useful UI examples and easy access to all the code.
W tym obszarze skupimy się na stronach, jednej z głównych rzeczy aplikacji Kirigami.
Kirigami apps are typically organized in Pages . Those 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, one 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.
KDE has Human Interface Guidelines (HIG) that go into detail about how to best design your application. The guidelines help ensure your application remains usable, consistent, and aesthetic.
A Kirigami.Page inherits from a Controls.Page , and as such you can use the latter's properties as well.

main.qml, który stworzyliśmy w naszym poprzednim samouczku:
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, but don't worry: Kirigami also supports scrollable pages. Kirigami.ScrollablePage is going to be our main page now.
OstrzeżenieIf you've gone ahead of the tutorial, you might have noticed that there is also such a thing as a ScrollView that you can use to contain your components. However, do NOT put a
ScrollablePageas this can cause problems. Children of a
ScrollablePageare functionally already in a
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
. In this case, we used one of the
i18nc() functions we explored in our previous tutorial to this end.
You could also choose to define your page within its own QML document. To do so, you'd create the new QML file, for example "StartPage.qml", add it to your
resources.qrc file, and set the window's first page to load it, like so:
pageStack.initialPage sets the initial Page of the application's page stack, and
converts the relative URL of the QML file into an absolute one.
There is further information about alternative page structures within our Kirigami documentation.
