Kirigami

QtQuick plugins to build user interfaces based on the KDE UX guidelines

Introduction

Kirigami is a set of QtQuick components at the moment targeted for mobile use (in the future desktop as well) targeting both Plasma Mobile and Android. It’s not a whole set of components, all the “Primitive” ones like buttons and textboxes are a job for QtQuickControls (soon QtQuickControls2) but it’s a set of high level components to make the creation of applications that look and feel great on mobile as well as desktop devices and follow the Kirigami Human Interface Guidelines.

Build examples to desktop

Build all examples available

mkdir build
cd build
cmake .. -DBUILD_EXAMPLES=ON
make

Than, you can run:

./examples/applicationitemapp/applicationitemapp
# or
./examples/galleryapp/kirigami2gallery

Build the gallery example app on Android

Make sure to install android-sdk, android-ndk and android-qt5-arch, where arch should be the same architecture that you aim to deploy.

mkdir build
cd build
cmake .. \
    -DQTANDROID_EXPORTED_TARGET=kirigami2gallery \
    -DBUILD_EXAMPLES=on \
    -DANDROID_APK_DIR=../examples/galleryapp \
    -DECM_DIR=/path/to/share/ECM/cmake \
    -DCMAKE_TOOLCHAIN_FILE=/usr/share/ECM/toolchain/Android.cmake \
    -DECM_ADDITIONAL_FIND_ROOT_PATH=/path/to/Qt5.7.0/5.7/{arch} \
    -DCMAKE_PREFIX_PATH=/path/to/Qt5.7.0/5.7/{arch}/path/to/Qt5Core \
    -DANDROID_NDK=/path/to/Android/Sdk/ndk-bundle \
    -DANDROID_SDK_ROOT=/path/to/Android/Sdk/ \
    -DANDROID_SDK_BUILD_TOOLS_REVISION=26.0.2 \
    -DCMAKE_INSTALL_PREFIX=/path/to/dummy/install/prefix

You need a -DCMAKE_INSTALL_PREFIX to somewhere in your home, but using an absolute path.

If you have a local checkout of the breeze-icons repo, you can avoid the cloning of the build dir by passing also -DBREEZEICONS_DIR=/path/to/existing/sources/of/breeze-icons

make create-apk-kirigami2gallery

Apk will be generated at ./kirigami2gallery_build_apk/build/outputs/apk/kirigami2gallery_build_apk-debug.apk.

To directly install on a phone:

adb install -r ./kirigami2gallery_build_apk/build/outputs/apk/kirigami2gallery_build_apk-debug.apk

To perform this, your device need to be configureted with USB debugging and install via USB in Developer options.

Some ambient variables must be set before the process: ANDROID_NDK, ANDROID_SDK_ROOT, Qt5_android and JAVA_HOME

export ANDROID_NDK=/path/to/android-ndk
export ANDROID_SDK_ROOT=/path/to/android-sdk
export Qt5_android=/path/to/android-qt5/5.7.0/{arch}
export PATH=$ANDROID_SDK_ROOT/platform-tools/:$PATH
# adapt the following path to your ant installation
export ANT=/usr/bin/ant
export JAVA_HOME=/path/to/lib/jvm/java-8-openjdk/

Build on your application Android, ship it together Kirigami

Build kirigami

Use the same procedure mentioned above (but without BUILD_EXAMPLES switch):

cd into kirigami sources directory;

Execute build script:

mkdir build
cd build

cmake ..  \
    -DCMAKE_TOOLCHAIN_FILE=/path/to/share/ECM/toolchain/Android.cmake\
    -DCMAKE_PREFIX_PATH=/path/to/Qt5.7.0/5.7/android_armv7/\
    -DCMAKE_INSTALL_PREFIX=/path/to/dummy/install/prefix\
    -DECM_DIR=/path/to/share/ECM/cmake

make
make install

Note: omit the make create-apk-kirigami2gallery step.

Build your application

This guide assumes that you build your application with CMake and use Extra CMake Modules (ECM) from KDE frameworks.
- cd into your application sources directory;
- Replace $yourapp with the actual name of your application;
- Execute build script:
```
mkdir build
cd build

cmake .. \
    -DCMAKE_TOOLCHAIN_FILE=/path/to/share/ECM/toolchain/Android.cmake \
    -DQTANDROID_EXPORTED_TARGET=$yourapp \
    -DANDROID_APK_DIR=../examples/galleryapp/ \
    -DCMAKE_PREFIX_PATH=/path/to/Qt5.7.0/5.7/android_armv7/ \
    -DCMAKE_INSTALL_PREFIX=/path/to/dummy/install/prefix
    
make
make install
make create-apk-$yourapp
```
- Note: -DCMAKE_INSTALL_PREFIX directory will be the same as where Kirigami was installed, since you need to create an apk package that contains both the kirigami build and the build of your application.

Build an application with qmake
