kirigami

Introduction

Kirigami is a set of QtQuick components for building adaptable UIs based on Qt Quick Controls 2. Its goal is to enable creation of applications that look and feel great on mobile as well as desktop devices and follow the KDE Human Interface Guidelines. The target of those components is anybody that wants to do an application using QtQuick as its main UI, especially if targeting a mobile platform, without adding many dependencies. They work on a variety of platforms, such as Plasma Mobile, Desktop Linux, Android, iOS and Windows. It is a Tier-1 KDE Framework starting with KDE Frameworks 5.37.

            }
        ]
    }
    contextDrawer: Kirigami.ContextDrawer {
        id: contextDrawer
    }
    pageStack.initialPage: mainPageComponent
    Component {
        id: mainPageComponent
        Kirigami.ScrollablePage {
            title: "Hello"
            actions {
                main: Kirigami.Action {
                    icon.name: sheet.sheetOpen ? "dialog-cancel" : "document-edit"
                    onTriggered: {
                        print("Action button in buttons page clicked");
                        sheet.sheetOpen = !sheet.sheetOpen
                    }
                }
                left: Kirigami.Action {
                    icon.name: "go-previous"
                    onTriggered: {
                        print("Left action triggered")
                    }
                }
                right: Kirigami.Action {
                    icon.name: "go-next"
                    onTriggered: {
                        print("Right action triggered")
                    }
                }
                contextualActions: [
                    Kirigami.Action {
                        text:"Action for buttons"
                        icon.name: "bookmarks"
                        onTriggered: print("Action 1 clicked")
                    },
                    Kirigami.Action {
                        text:"Action 2"
                        icon.name: "folder"
                        enabled: false
                    },
                    Kirigami.Action {
                        text: "Action for Sheet"
                        visible: sheet.sheetOpen
                    }
                ]
            }
            Kirigami.OverlaySheet {
                id: sheet
                onSheetOpenChanged: page.actions.main.checked = sheetOpen
                QQC2.Label {
                    wrapMode: Text.WordWrap
                    text: "Lorem ipsum dolor sit amet"
                }
            }
            //Page contents...
        }
    }
}

Deployment

CMake is recomended for both building Kirigami and the project using it, qmake is supported as well, so we can have several configurations, depending what is the host build system and how the deployment needs to be done. Kirigami can be built in two ways: both as a module or statically linked in the application, leading to four combinations:

• Kirigami built as a module with CMake
• Kirigami statically built with CMake (needed to link statically from applications built with CMake)
• Kirigami built as a module with qmake
• Kirigami statically built with qmake (needed to link statically from applications built with qmake)

The simplest and recomended way to use Kirigami is to just use the module provided by the Linux distribution, or build it as a module and deploy it together the main application. For example when building an application on Android with CMake, if Kirigami for Android is built and installed in the same temporary directory before the application, the create-apk- step of the application will include the Kirigami files as well in the APK.

If qmake needs to be used, it's recomended to follow the schema of the example app present in the folder examples/minimalqmake of the Kirigami source code.

It will use Kirigami statically linked only on Android, while on desktop systems it will use the version provided by the distribution. What platforms use the static version and what the dynamic one can be freely adjusted. The application needs to have a folder called "3rdparty" containing clones of two KDE repositories: kirigami and breeze-icons (available at git://anongit.kde.org/kirigami.git and git://anongit.kde.org/breeze-icons.git). The relevant part in the .pro file is:

android: {
    include(3rdparty/kirigami/kirigami.pri)
}

While the main.cpp file will have something like:

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#ifdef Q_OS_ANDROID
#include "./3rdparty/kirigami/src/kirigamiplugin.h"
#endif

int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;

#ifdef Q_OS_ANDROID
    KirigamiPlugin::getInstance().registerTypes();
#endif
....
}
