GUI creation for boost::graph
Hi, I whish to create a boost graph gui using qt However I have a problem I do not know how to link qt to boost graph. If I use bundle property of qt object could I get next and previous node from the qtobject? I am thinking about using a sets indexed by qtobject adress but I seems really painfull for managing memory. Particularly I want my implement my algorigthm on the graph and able to modify the graphical object from the boost::graph but also able to modify the graph from graphical qt object Any ideas? Bastien

Unless you put an external map from QObjects to BGL nodes, you will not be able to do that lookup.

You will need some kind of lookup table like that, but it could be a hash table. It looks like QObject has a property mechanism, so you might be able to use that to link back to the BGL graph.

You might want to take a look at this part of QObject; it might be the way to do the mapping you want. -- Jeremiah Willcock

Hi, I did this prototype for my company last fall: http://youtube.com/watch?v=OHdc-wtSmg0 But its not connected to Qt, Qt is only used as a frontend here. I think sofar its best, when you have a central Object which manages the graph, and can be queried from Qt. Also of course you could try to get boost::graph with the Model/View Concept of Qt working, that would be indeed neat. regards, Jens Weller -- Schon gehört?
