PubNub C-core for Qt

The PubNub Qt SDK is a part of the PubNub C-core SDK. Unlike the C++ wrapper, which wraps a full-featured C-core platform, this is a Qt-native C-core of sorts. It provides its own Qt API, using as many C-core modules as possible.

Supported Qt versions

This SDK works with Qt5 and Qt6. It builds on Qt4, too, but there are some runtime issues, e.g.: publishing a JSON object fails.

If you have many Qt versions on your machine, use Qt5 or Qt6 (while Qt6 is Unix-tested only). To select the correct version, you can use the qtchooser app. For example, run qtchooser -run-tool=qmake -qt=5 pubnub.pro. This creates a Makefile that uses Qt5 tools.

Of course, you may also use the provided Qt projects in Qt Creator.

Sample projects

We provide the following sample projects for your convenience:

  • pubnub.pro, which builds a Qt command line application that executes most of the Pubnub transactions/operations. It's similar to pubnub_sync_sample or pubnub_callback_sample from the C-core SDK.
  • pubnub_gui.pro, which builds a Qt GUI application, a minimalistic Pubnub console.

To build the projects:

  1. Run qmake pubnub.pro or qmakepubnub_gui.pro
  2. Run make or, if you use MSVC on Windows, nmake or jom.

Additional defines

With PubNub Qt SDK, we provided some additional defines that change the behavior of the SDK:

Flag Required Description
PUBNUB_QT Required Enables C-core code to fit Qt requirements.
PUBNUB_QT_MOVE_TO_THREAD Pptional, enabled by default Uses the moveToThread() function to organize SDK timers.
