qt_eventdispatcher_epoll Build Status

epoll(7)-based event dispatcher for Qt (for Linux only)

Features

  • very fast :-)
  • compatibility with Qt4 and Qt 5
  • does not use any private Qt headers
  • passes Qt 4 and Qt 5 event dispatcher, event loop, timer and socket notifier tests

Requirements

  • Linux kernel >= 2.6.27
  • glibc >= 2.9
  • Qt >= 4.2.1 (may work with an older Qt but this has not been tested)

Build

cd src
qmake
make

The above commands will generate the static library and .prl file in ../lib directory.

Install

After completing Build step run

sudo make install

This will install eventdispatcher_epoll.h to /usr/include, libeventdispatcher_epoll.a and libeventdispatcher_epoll.prl to /usr/lib, eventdispatcher_epoll.pc to /usr/lib/pkgconfig.

Usage (Qt 4)

Simply include the header file and instantiate the dispatcher in main() before creating the Qt application object.

#include "eventdispatcher_epoll.h"

int main(int argc, char** argv)
{
    EventDispatcherEPoll dispatcher;
    QCoreApplication app(argc, argv);

    // ...

    return app.exec();
}

And add these lines to the .pro file:

CONFIG    += link_pkgconfig
PKGCONFIG += eventdispatcher_epoll

or

HEADERS += /path/to/eventdispatcher_epoll.h
LIBS    += -L/path/to/library -leventdispatcher_epoll

Usage (Qt 5)

Simply include the header file and instantiate the dispatcher in main() before creating the Qt application object.

#include "eventdispatcher_epoll.h"

int main(int argc, char** argv)
{
    QCoreApplication::setEventDispatcher(new EventDispatcherEPoll);
    QCoreApplication app(argc, argv);

    // ...

    return app.exec();
}

And add these lines to the .pro file:

CONFIG    += link_pkgconfig
PKGCONFIG += eventdispatcher_epoll

or

HEADERS += /path/to/eventdispatcher_epoll.h
LIBS    += -L/path/to/library -leventdispatcher_epoll

Qt 5 allows to specify a custom event dispatcher for the thread:

QThread* thr = new QThread;
thr->setEventDispatcher(new EventDispatcherEPoll);
