This release uses QT 4.2.0 and the new GraphicsView framework. A library was added as a repository for widgets used to display graph features, such as styles or node lists. Custom nodes attributes can now be added to nodes through the graph interface. An abstract factory system allows the registration of custom nodes to be displayed in the graph view. New samples demonstrate style modifications and how to display custom node attributes (9/11 social graph).
This release fixes serious bugs in GraphItemView
and GraphItemModel, and
adds better support for GCC compilation. It now
works with the latest
KDE4 qt-copy (qt 4.1.3).
This release supports a full set of features (insertion/suppression/edition) to modify its graph, and all modifications are reflected to and from the Interview model. Qanava is now distributed under the GNU LGPL.
Qanava no longer depends on QCanvas and does all
its drawing as a standalone widget using Arthur.
The model/view system now supports on the fly node
insertion and suppression. Grid architecture has
been cleaned, and the usual regular grid can now
be changed with a check board one. The rendering
code has received numerous optimizations and the
UI is now much more reactive than with QCanvas
code. This is the first version that is stable
enough to be considered usable as a library in
"unstable" code.
This release is a full QT4 library and uses the QtCanvas version of QCanvas shipped with QT4.1+. Many bugs in the graph description module have been fixed.
