FangTian for Wayland and OpenHarmony Applications ​

The FangTian window engine integrates multiple application ecosystems, allowing Linux and OpenHarmony applications to run on openEuler simultaneously.

Wayland Application Support ​

Wayland Protocols ​

To support native Linux applications, FangTian is compatible with Wayland applications. Due to the complexity of Wayland protocols, currently, FangTian supports core, stable, and unstable protocols.

Application Running ​

1. After starting the FangTian engine, start the SA of the Wayland adapter.

   shell

   mkdir -p ~/tmp
   sa_main /system/profile/ft/ft_wl.xml > ~/tmp/ftwlsa.log 2>&1 &

2. Configure the Wayland environment.

   shell

   export XDG_SESSION_TYPE=wayland
   export WAYLAND_DISPLAY="wayland-0"
   export QT_QPA_PLATFORMTHEME=ukui

3. Download and install Linux Wayland applications.

   shell

   sudo dnf install kylin-calculator deepin-terminal

4. The following applications are installed:

OpenHarmony Application Support ​

ArkUI Framework ​

Currently, FangTian supports some ArkUI controls, such as texts, buttons, and images. Developers can develop Harmony applications using DevEco Studio.

Application Source Code ​

• Electronic Album
• Simple Calculator

Installation and Running ​

1. Copy the .hap file of the application from DevEco Studio to an openEuler directory, for example, ~/apps/tmp.

2. Decompress the .hap file, for example, eletronicAlbum.hap.

   shell

   unzip eletronicAlbum.hap

   After the decompression, the application is in ~/apps/tmp/eletronicAlbum.

3. After starting the FangTian engine, run the application.

   shell

   hap_executor ~/apps/tmp/eletronicAlbum

4. The following window is displayed:

Constraints ​

• Currently, ArkUI controls are not fully supported. Web and video controls are unavailable. You need to develop and port the NAPI interfaces.

• ArkUI supports only the x86 architecture in this version.
