RE: [gtkmm] How to capture Enter pressed on a Entry?

[Dale Hirt <dale sbcltd com>]

Oops, my mistake.  It appears that you cannot use set_events after the
widget has been realized.  The documentation says the following:

******************
	The event mask determines which events a widget will receive. Keep
in mind that different widgets have different default event masks, and by
changing the event mask you may disrupt a widget's functionality, so be
careful. This function must be called while a widget is unrealized. Consider
add_events() for widgets that are already realized, or if you want to
preserve the existing event mask
*******************

Try using add_events() instead of set_events().

Thanks.

	I tried but doesn't worked. I don't know what do you mean with
realized. I moved it out of the constructor and tried whe I cans see the
form. The error message is exactly the same.
