There is quite a lot of traffic and clones actually: Please remember to star the project and reports bugs....

• CHANGELOG 20191110: Complete rewrite of LineGrid, various cosmetic fixes and bugfixes (update to v0.15.0).
• CHANGELOG 20190825: Maintenance release, add more flexible content creation methods in qan::Graph.
• CHANGELOG.md

QuickQanava is a C++14 library designed to display graphs and relational content in a Qt/QML application. QuickQanava provide QML components and C++ classes to visualize medium-sized directed graphs in a C++/QML application. QuickQanava focus on displaying relational content into a dynamic user interface with DnD support, resizable content and visual creation of topology. More advanced layouts algorithms might be integrated in future versions.

QuickQanava main repository is hosted on GitHub: http://cneben.github.io/QuickQanava/index.html

QuickQanava is primarily developed for Linux with Qt 5.13 with MSVC2017 and g++7 (minimal required Qt version is Qt 5.10)

• Graph Data Model

  • Ports and Docks
  • Visual node connection
  • Selection
  • Groups

• Styling

• Advanced use, custom topology

For any questions, please contact: [email protected]

QuickQanava focus on writing content delegates in QML (even if they could be 100% defined in C++, a QML engine is still necessary in the background).

Dependencies

• Qt 5.10 is mandatory for Qt Quick Shapes support.
• Google Test is a GTpo dependency, it is optional for QuickQanava until you intent to use a graph with custom non-STL/non-Qt containers:

Building

Get the latest QuickQanava sources:

git clone https://github.com/cneben/QuickQanava
cd QuickQanava

Or install as a Git submodule:

$ git submodule add https://github.com/cneben/QuickQanava
$ git submodule update

QuickQanava could be used with either qmake or CMake build configuration system.

qmake	cmake
Static build, no QML module, all resources are linked statically trough QRC	Installable or embedable, QuickQanava is loaded using a QML module that need to be installed

Using qmake (preferred and supported way of integrating QuickQanava):

1. Open quickqanava.pro in QtCreator.

2. Select a kit, build and launch samples.

⚠️ CMake support is "community maintained"

or with (CMake >= 3.5) and Qt Creator:

1. Open CMakeLists.txt in QtCreator.

2. In 'Projects' panel, set DBUILD_SAMPLES option to true in CMake configuration panel.

3. Select a kit, build and launch samples.

Or manually in command line using CMake:

$ cd QuickQanava
$ mkdir build
$ cd build

# IF QT_DIR IS CONFIGURED AND QMAKE IN PATH
$ cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SAMPLES=TRUE ..

# IF QT DIR IS NOT CONFIGURED, CONFIGURE KIT MANUALLY
$ cmake -DCMAKE_PREFIX_PATH="/home/b/Qt/5.11.0/gcc_64" -DQT_QMAKE_EXECUTABLE="/home/b/Qt/5.11.0/gcc_64/bin/qmake"  -DBUILD_SAMPLES=TRUE ../QuickQanava/

$ cmake --build .
# Then run the samples in ./samples

# Eventually make install

Detailled instructions: Installation

Note that a previously installed "QML plugin" version of QuickQanava might interfere with a fully static build using direct .pri inclusion. Typical error message looks like:

QQmlApplicationEngine failed to load component
qrc:/nodes.qml:33 module "QuickQanava" plugin "quickqanavaplugin" not found

QuickQanava and QuickContainers plugins directories could be removed manually from $QTDIR\..\qml to fix the problem (ex: rm -rf '~/Qt/5.11.1/gcc_64/qml/QuickQanava').

Roadmap / Changelog

• v0.15.x:
  • Add full support for groups inside group (ie subgraphs).
  • Update geometry creation interface and delegate management.
• v0.16.x:
  • Add support for direct visual dragging of port items.
  • 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).
