it does. you must have a mistake in your code. take a look at the
example code in testgtk.c covering shaped windows. you'll find stuff
that does this for shaped windows that you can drag around the screen
at will.

Pointer grabs are not a feature of GTK, but of the X Window
system. There is (almost) no way to avoid them regardless of the
widget toolkit one uses or the language its written in.

What signals are you using ?
