Hello, Thanks to the great help of Olivier, I've now stuffs in place to develop an Elisa plugin.
Now, I want to set a "dynamic" background. This background will be a map rendered by PyCairo. But of course, the map will dynamically change. As a first step, Oliver helped me to put a Cairo sample in a pgm Image. It works great. But now I don't know how to continue. I see two different possibilites : 1) Map the Image widget (or anything else ?) to a function or a memory place that provide the picture. (I suppose that it is how Video works) 2) Manually refresh the controller every 1/10s which seems to be ugly. So, how would you do that ? Bonus point : I would really appreciate to have this background be seen by transparency from other controllers. You know, justlike Video. But that's really a bonus point ;-) Thanks, Lionel
