Re: Widget help needed...

[Bruno Tavares <bat ip pt>]

Ok,

Now i have another problem. The widget that i'm monitoring is enclosed
in an object, so i need to make the alarm available only to this object
scope. I dont know how to do this since the Gtk wheel is global.

Yet another question, i need an event that tells me that thar widget is
no longer visible so i can remove the alarm, any one recomended??

Thank you
