Re: [gtk-list] Getting check button children

[Eric Harlow <linuxgeek yahoo com>]

Without seeing how you're installing the event handler / signal
handler, it's hard to say.  Check to see which events the buttons are
handling.  The gtk_toggle_button_set_state button does call the
gtk_button_clicked function which, I believe, ends up signaling a
"button_clicked" and if you're listening to it and calling
setStateFalse from there, that might cause an infinite loop to occur.
