Re: GSignal connect with struct *pointer

[Matthias Mann <matman matman24 org>]

No! This takes no effect. Isn't it the same? I tried your
suggestion but noting is better. And i think it's no metter
to use '&struct' or '*struct'. The problem is that
g_signal_connect() is unable to give the adress of 'struct'
to the callback function. Maybe the gpointer has no
possibility to transport the location of a structure variable.
Have no more idea. What's wrang here?
