Hi Mohmed,

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.
