Re: Button not working <<<<<

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

The documentation of signals is poor in present releases of gtkmm. That 
will change in the future. Then the documentation will be copied from 
gtk+ to gtkmm (with small changes). The documentation of GtkButton's 
"activate" signal in gtk+ says

"The ::activate signal on GtkButton is an action signal and emitting it 
causes the button to animate press then release. Applications should 
never connect to this signal, but use the "clicked" signal."

If you connect to signal_clicked() instead of signal_activate() your 
program works.

Have you seen the "Programming with gtkmm" book?
