Compositor API#

This API handles communication with the display server. If possible it is recommended to use use libblight instead

Example Usage#

#include <QDebug>
#include <liboxide/dbus.h>

using namespace codes::eeems::blight1;

int main(int argc, char* argv[]){
    auto bus = QDBusConnection::systemBus();
    Compositor compositor(BLIGHT_SERVICE, "/", bus);
    qDebug() << "Display server PID:" << compositor.pid();
    return EXIT_SUCCESS;
}

#!/bin/bash
echo "Display server PID: $(rot compositor get pid)"
echo "Display server surfaces:"
rot compositor call getSurfaces | jq -r '.[]'
