Re: windows not send widget to callback

[Flavio Alberto Lopes Soares <flavio maqplas com br>]

I believe that I found the problem, but I don't have a solution :( !

I made the interface using glade-2 and I add in field "Object" my 
struct (a structure that I use in my program, not any struct from Gtk)
that has the information about these window (key pressed, info about
buttons, max buttons in these window, function called by these buttons, 
etc) and these field "Object" have to be some widget, I was using the 
concept of glade 0.6.4 that we can send any data to callback.

Well, I attemp to use my internal structures as global variables but someone have
a better way to do this ?

Thanks for all help
