Cy3 node selected event

[Jiao, Dazhi]

Hi,

 

In Cy3 is there any new way for capture the node selected event? I know in Cy2 one can use the GraphViewChangeEvent in giny but wonder if there is any new method in Cy3 for this types of events.

 

Thanks,

Dazhi

Since selected state is now stored as an attribute of the node in the default node table, you can listen to the RowsSetEvent.  When you hear the event, check to see if it's from the table you care about and whether that particular event contains selection events.  Something like this:

void handleEvent(RowsSetEvent e) {

if (e.getSource() != tableICareAbout)

return;

if (!e.containsColumn(CyNetwork.SELECTED)

return;

for (RowSetRecord record : e.getColumnRecords(CyNetwork.SELECTED)) {

// do something for the nodes you care about!

}

}

Mike

Thanks for the answer. One more question: how do I register a RowsSetListener to listen to the RowsSetEvent? I looked around in the Cy3 API but couldn’t find an “addRowsSetListener” method in any class.

There is a cookbook at

Look at sample08.
