Recap
So far, we have managed to build a simple app that can display cards. However, we don't yet have a way of adding new cards to our card view.
In this tutorial, we'll be looking at Kirigami actions. These will help us add interactivity to our app in a consistent, fast, and accessible way.
Aktionen
A Kirigami.Action encapsulates a user interface action. We can use these to provide our applications with easy-to-reach actions that are essential to their functionality.

Page actions on the desktop

Page actions on mobile
If you have used Kirigami apps before, you have certainly interacted with Kirigami Actions. In this image, we can see actions to the right of the page title with various icons. Kirigami Actions can be displayed in several ways and can do a wide variety of things.
Adding countdowns
A countdown app is pretty useless without the ability to add countdowns. Let's create an action that'll let us do this.
pageStack.initialPage: Kirigami.ScrollablePage {
...
actions.main: Kirigami.Action {
id: addAction
icon.name: "list-add"
text: i18nc("@action:button", "Add kountdown")
onTriggered: kountdownModel.append({
name: "Kirigami Action added card!",
description: "Congratulations, your Kirigami Action works!",
date: 1000
})
}
...
}
We are placing our Kirigami Action within our main page from our previous tutorials. If we wanted to, we could add more actions to our page (and even nest actions within actions!).
Kirigami.Action
components are used as contextual actions within Kirigami pages. We are setting it specifically to the
actions.main
property of our
Kirigami.Page
: the actions
object has properties that let us set different actions in different positions, but since our "Add kountdown" action is central to our UI we are setting it as the main action of this page.
The id
and text
properties should be familiar from previous tutorials. However, the inherited Action.icon property should be interesting: it is an object with several properties letting you display certain icons for your actions. Fortunately, to use KDE icons all we need to do is provide the name property for the icon property, icon.name
.
Note
Cuttlefish is a KDE application that lets you view all the icons that you can use for your application. It offers a number of useful features such as previews of their appearance across different installed themes, previews at different sizes, and more. You might find it a useful tool when deciding on which icons to use in your application.
Many of KDE's icons follow the FreeDesktop Icon Naming specification. Therefore, you might also find it useful to consult The FreeDesktop project's website, which lists all cross-desktop compatible icon names.
The
onTriggered
signal handler is the most important. This is what our action will do when it is used. You'll notice that in our example we're using the method kountdownModel.append of the kountdownModel
we created in our previous tutorial. This method lets us append a new element to our list model. We are providing it with an object (indicated by curly braces {}
) that has the relevant properties for our countdowns (name
, description
, and a placeholder date
).

Each time we click our "Add kountdown" button on the top right, our custom countdown is added

Mobile version
Global drawer
Did you notice those three lines next to the page title on the previous screenshot? That's a hamburger menu that opens a Kirigami.GlobalDrawer . Global drawers are useful for global navigation and actions: in other words, those things you might need to use throughout your application. We are going to create a simple global drawer that includes a "quit" button.
Kirigami.ApplicationWindow {
id: root
...
globalDrawer: Kirigami.GlobalDrawer {
isMenu: true
actions: [
Kirigami.Action {
text: i18n("Quit")
icon.name: "gtk-quit"
shortcut: StandardKey.Quit
onTriggered: Qt.quit()
}
]
}
...
}
Here, we put our global drawer inside our application window. The main property we need to pay attention to is GlobalDrawer.actions , which takes the form of an array of Kirigami.Action components. This action has an appropriate icon and executes the Qt.quit() function when triggered, closing the application.
Since we are keeping our global drawer simple for now, we are setting the
GlobalDrawer.isMenu
property to true
. This displays our global drawer as a normal application menu, taking up less space than the default global drawer pane.
