Btw, I had an issue when writing the VirtualBox mouse input_server add-on.
Because virtualbox only passes absolute coordinates to it, I'm only able to
send B_MOUSE_MOVED messages without the buttons field. Some apps like Tracker
don't really like this and fail to handle selections or drags because it
doesn't see the buttons as being pressed.
This sounds really strange. Why would you be unable to send button state in
each message? What does it have to do with coordinates?
It's just that VBox sends all button events through the PS/2 port as regular
mouse events, and only the absolute position is available through their fake
PCI device. So input_server gets a mixture of B_MOUSE_DOWN|UP with relative
move of 0,0 and B_MOUSE_MOVED with the absolute positions but no button data.
Oddly app_server doesn't have problem with this when moving windows around, but
Tracker can't start a selection or drag. Also releasing the mouse in a menu
doesn't invoke it either.
