Re: Add a signal to an object

[Stefan Kost <kost imn htwk-leipzig de>]

Hi Felix,

your networking code needs to be derived from gobject. Then you can add the
signal to that object and connect a callback for each canvas item to that object.
The signal calback can set at new color on its object (you can pass the canvas
item to user-data).
