QuickQanava is a C++14 library designed to display graphs and relational content in a QtQuick application. QuickQanava provide QML components and C++ classes to visualize medium-sized directed graphs in a C++/QML application. QuickQanava does not provide advanced layout algorithms, but rather focus on displaying relational content in advanced dynamic user interfaces (with DnD support, resizable content, visual connection of nodes).

QuickQanava main repository is hosted on GitHub: https://github.com/cneben/quickqanava

QuickQanava is primarily developed with Qt >= 5.13 with MSVC2015 and g++7. minimal required Qt version is Qt 5.10.

Please refer to Installation manual and Graph, Nodes and Graph sections for more information about installing and using QuickQanava.

    • Fix current qan::LineGrid bugs
    • Add "snap to grid" support.
  • v0.17.x:
    • Rewrite CMake configuration, add install step, use QML plugins.
  • v1.: Advanced edge visualization
    • Add better support for graph fine grained locking strategies.
    • Add simple layout algorithms (force directed, tree).
    • Publish the 4k sample (40k is probably too much for QML without dedicated culling and LOD code).
