IDapython GraphViewer Object and IDA 6.6

[Mouad Abouhali]

Hello hello,

  

 I'm working on a plugin using IDApython. I'm generating a graph view using GraphViewer class and that works fine. My problem is that I can't select text inside node (or basic blocs) using the mouse. Indeed, when I move the cursor using the keyboard arrows, I can select a text (ex: ebx) and it is automatically highlighted. 

Any idea on how to trigger this behaviour. 

Context: IDA 6.6 under linux.

Thanks in advance.
