At the beginning, I was trying to set up a text wrap for the new dialog, but after read the gtkmm doc, I give up
developer.gnome.org/gtkmm/stable … eed675e7a5
Personally speaking, I prefer to using ghig guide: developer.gnome.org/hig-book/3.0 … rt.html.en
The dialog is using a text inside a scrollable window because in some cases the warning text is extremely huge (long) and then gtk api crashes. The real solution would be trim the message to a maximum length and optionally give one additional dialog to see the full message in a memo type widget. I did the scrolled window as an intermediate solution.
Please take in mind the possibility of a very long text message when designing the alternative solution.
