A simple TCP/IP network client for use in Touch Portal plugins which wish to utilize the Qt C++ library/framework.
- Handles bi-directional network transfer and JSON encode/decode of Touch Portal messages.
- Uses Qt signals to deliver messages from Touch Portal and inform of connection status changes.
- Send messages to Touch Portal using Qt slots and/or direct client method invocations.
- Optimized for maximum throughput, no unnecessary data processing is performed (eg. assumes plugin author validates their own data before sending).
- Includes some optional convenience methods for working with incoming action/connector data (eg. convert JSON array of objects to a
QMapwith the data IDs as keys). - Asynchronous socket operations, fully reentrant methods, and can be run in a separate thread if needed (with queued signals/slots communication).
- Supports Touch Portal plugin API up to v6 (latest released version). Will be updated for future versions as they are released.
- Depends on the
QtCoreandQtNetworklibraries/modules. - Requires a Qt event loop to process data (uses asynchronous socket operations).
- Typically this would be provided by
Q[Core|Gui]Application::exec(), but could also be wrapped in a custom class with own event loop for use outside of Qt applications (for example).
- Typically this would be provided by
- The client should work on any platform supported by
QtNetworklibrary.
Tested with Qt versions 5.12.12, 5.15.7, 6.4.1 on Windows 10/11, MacOS (Big Sur and later), and Linux (Debian 9 (buster) / Ubuntu 18.04 (bionic)).
The client consists of a single class -- TPClientQt. The simplest way to use it in a project is to just include the source code files directly in the plugin build.
It can also be built/used as a shared or static library. The included CMake project file can be used to build this. By default it builds a shared library (DLL),
but setting the BUILD_SHARED_LIBS variable to 'OFF/FALSE' will build the static version instead.
In either case, just #include "TPClientQt.h" somewhere in your plugin code and you're good to go.

I will add a simpler example to this repository ASAP.
