Using gtk_window_new() will create a window which the user can re-size
and maximize. I don't want my user to be able to perform these
actions. In my old Win32 days I'd achieve it by creating a window,
then removing the styles WS_THICKFRAME
motion events whenever the mouse
pointer is over/in my drawing area, even when the window containing that
drawing area is not active.
This was surprising for me. I want events only when the window is the
active one. What is the correct method to achieve that behavior?
Thanks,
Stefan Salewski
