libqtlxqt

LXQt system integration plugin for Qt.

With this plugin, all Qt-based programs can adopt settings of LXQt, such as the icon theme.

To use the plugin in Qt 5, we have to export the environment variable QT_QPA_PLATFORMTHEME=lxqt. Then every Qt5 program can load the theme plugin. If, for some unknown reasons, the plugin is not loaded, we can debug the plugin by exporting QT_DEBUG_PLUGINS=1. Then, Qt5 will print detailed information and error messages about all plugins in the console when running any Qt5 programs.
