kgraphviewer and QML ?

[kleag at free.fr]

Hi,

I'm working on a new GUI for the linguistic analyzer of my lab:
https://github.com/aymara/lima/tree/master/lima_gui

The interface is currently purely QML based with text based displays. A standard way at looking results is through graphs like the one attached. In fact, I started kgraphviewer (kgv) to visualize these graphs…

So, I thinked about integrating the kgraphviewer kpart in the GUI and then discovered that it is not quite possible. Or at least complex and inefficient. 

I'd like to get your advice on what would be the right solution. I thinked at several possibilities:
- use the graphivz lib API to generate an image and show the image in the UI;
- use the kgv API to load the graph without dispalying it in the widget and export it to an image like above;
- use the kgv API to load the graph and reimplement in QML the kgv canvas elements (based on QAbstractGraphicsShapeItem).

The latter seems to be the best but also complicated with the current QML API.

What do you think ? Does one of these solutions seems reasonable ? Other ideas ?

Thanks for your attention ?

Regards,

Gaël
