A few days ago the release of the new version of the open
platform webOS Open Source Edition 2.15, which can be used in
various portable devices, dashboards, and car infotainment systems.
In this new version that is presented, the
developers mention that have strived to provide a better Qt
development experience, since the rendering performance and
animation quality of Qt applications have been improved, as well as keyboard
and mouse support, among other things.
For those who are unfamiliar with WebOS Open Source
Edition, you should know that can be used on a variety of portable devices, dashboards, and
infotainment systems for automobiles. Raspberry Pi 4
boards are considered the reference hardware platform.
WebOS was originally developed by Palm in 2008 and
was used in the Palm Pre and Pixie smartphones. The acquisition of Palm in 2010 passed the platform to
Hewlett-Packard, after which HP tried to use the platform in
its printers, tablets, laptops, and PCs.
In 2012, HP announced the transfer of webOS to an open-source project independent and in 2013
began to open the source code of its components. In 2018, the webOS Open Source Edition project was founded, Through
which LG tried to return to an open development model, attract other
participants, and expand the range of webOS-compatible devices.
The key components of webOS are the System and
Application Manager (SAM), which is responsible for running applications and
services, and the Luna Surface Manager (LSM), which forms the user interface.
The components are written using the Qt framework and the Chromium browser
engine.
Rendering is done through a composite
manager using the Wayland protocol. To develop custom applications it is
proposed to use web technologies (CSS, HTML5, and JavaScript) and the Enact
framework based on React, but it is also possible to create programs in C and
C++ with an interface based on Qt.
