The Intent IPC framework has a stable API now and is fully documented, shipping with examples. It’s the QT culture, and it’s what attracts everyone who works with us. Be aware that any non-QML application, such as a native C++ compiled executable, will break this setup for developers on machines without Wayland support. this application will be active for 30 days. In contrast, non-Qt applications need to provide support for the required, open Wayland text input protocol. Writing an application to run as a client within the application manager is similar to writing a stand-alone QML application, except for these three additional tasks: If you write a QML application, make your QML scene's root element an ApplicationManagerWindow; or derive your own custom root item from it.

Qt Application Manager (or appman) is a Qt module targeted for embedded devices. For example, in low-memory situations, you want to gracefully terminate applications that the user hasn't interacted with in a while. If you do not specify an install-prefix when you run qmake, then the application manager will behave like a standard Qt module: in developer builds, the binaries will be compiled directly to ${qtbase}/bin; in prefix builds, the binaries will be compiled to ${builddir}/bin; If you specify an install-prefix, this means: Qt and respective logos are trademarks of The Qt Company Ltd. in Finland and/or other countries worldwide.

Through the Wayland protocol, this virtual keyboard component can then be transparently used from any Qt/QML application for full internationalized text input, without any special provisions on the application side. Dynamically installed applications are described by a single manifest file in their root directory, called info.yaml. Since UI applications typically have to be stopped and restarted multiple times during the up-time of an embedded system, and given the fact that most customers have tight constraints on the startup times of UI applications, the application manager implements some tricks to improve the startup performance: any application type that relies on a runtime component, such as QML or HTML, can be quick-launched.
