Qt VirtualKeyboard 不需要输入法做后端，其以插件插件形式提供功能，库安装在 <QT>/plugins/virtualkeyboard 目录下，中文拼音输入法由 qtvirtualkeyboard_pinyin.dll/qtvirtualkeyboard_pinyin.so 提供功能。

Ubuntu 系统 apt 安装该组件不支持中文拼音输入，需要卸载 Qt VirtualKeyboard 组件后自行通过官方源码编译安装。在 <https://download.qt.io> 的不同 official releases 中的 submodules 下可以找到不同版本的源码，例如，对应 Qt 5.15.10 的 VirtualKeyboard 下载连接如下：
|
|

|
|
|
|

- [qtvirtualkeyboard-everywhere-opensource-src-5.15.10.tar.xz](https://download.qt.io/official_releases/qt/5.15/5.15.10/submodules/qtvirtualkeyboard-everywhere-opensource-src-5.15.10.tar.xz)
