Invoking window at the top left corner

["SaiKamesh Rathinasabapathy" <rsaikamesh gmail com>]

Hi,

I have created a window in c++ by deriving a class from Gtk::Window.  I compiled my program and created executable.
I have put that executable in desktop. The problem is when I run the executable  the window is invoked almost at the center of the desktop. But I want the window to be invoked at the top left corner of the desktop( or screen we can say ) with out using move() function. 

Thank you.
