[pygtk] Info neded : DrawingArea

[euro_ii at libero.it]

Hi Guys,
I have 3 question.
1)
It's possible to crate custom widgets like 
edittext inside the drawingArea attached to the mouse pointer so when i move 
the mouse in the drawingArea the edit text follow the mouse and when i type 
some keyboar key the values gose directly in to the edit text?
2)
It's possible 
to attach an event like mouse doubleclick at a line created with the .....
window.draw_line(.  function. ?
3)
It's possible to make a sort of highlight on 
the entity in the DrawingArea so when i move the mouse over the  line the line 
change the color?

Thanks
Matteo
