If you're looking on regular way to track mouse in your BViews, you will find 
everything and more in this BeNewsletter article by Owen Smith of the old good 
days, "Developers' Workshop: The Bitchin' Async"

It's online here:
http://www.haiku-os.org/legacy-docs/benewsletter/Issue3-46.html

For a simple and sample usage code, you can look at several place in Haiku code 
source tree. For instance:
src/apps/pulse/CPUButton.cpp

To track mouse events outside your view (aka everywhere over "desktop", the 
trick is to use SetEventMask(B_POINTER_EVENTS), not 
SetMouseEventMask(B_POINTER_EVENTS), so your Mouse* hooks will be called even 
when the mouse will be outside your view.

Check those two BView methods documentation for details:
http://www.haiku-os.org/legacy-docs/bebook/BView.html#BView_SetEventMask

Hope this help.

Bye,
  Philippe.
