Hi all,
Sorry I think I didn't explain my doubt clearly.
Support we have two DFBTerms say DFBTerm1 and DFBTerm2.
DFBTerm1 will have a window manager and DFBTerm2 will have a window
manager .
Current focus is in DFBTerm2 ,now when I click the DFBTerm1 window ,
The focus goes to DFBTerm1.
DFBTerm1 is one process and DFBTerm2 is another process.
To shift the focus, I guess, DFBTerm2 will receive FOCUS_OUT Event
and
DFBTerm1 will receive FOCUS_IN Event. Then MOUSE_CLICK will be
Passed to DFBTerm1.
I want to know who is taking care of the above, i.e.
how the decision is taken,to which process to send the mouse
event.
Since each Process is having its own window manager.
Regards,
Dharma

No, the _dfb_windowstack_inputdevice_listener is a global
reaction which means that it can run globally and is executed
synchronously by the caller of fusion_reactor_dispatch,
no matter which Fusionee attached the reaction.
So this function still runs in the master only and calls the WM
which decides which window the event should go to. It creates a
window event and dispatches it to the window via its reactor.
Input Driver => (InputReactor) -> windowstack input listener -> WM
process input => (WindowReactor)
Via the window reactor the event will be dispatched to the corresponding
process which has local reactions, e.g. to store the event in a local
event queue (DirectFBEventBuffer).
