Handling exceptions in gtkmm

["SaiKamesh Rathinasabapathy" <rsaikamesh gmail com>]

Hi,
I am using gtkmm 4.0.3 to create user interface in my application.My OS is ubuntu.
Now i am doing error logging in my application. I do not know, What are
the exceptions may occur in gtkmm and how to handle those exceptions.
Is implicit exception throwing possible in gtkmm or should we throw the
exceptions explicitly using "throw" statement? and what is the
exception class hierarchy in gtkmm?. If possible, please send me
example program. 

Thanks in advance.
