add prot struct member to hold masks for detecting the start of a protocol
2000-12-09 James Henstridge <james@daa.com.au>
* gdk/linux-fb/gdkmouse-fb.c (GdkFBMouseDevice): add prot struct
member to hold masks for detecting the start of a protocol packet.
(mouse_devs): add packet start masks for ps2 and ms device types.
Left the mask for fidmour blank, as I have no idea what it should
be.
(handle_mouse_io): skip bytes until we get to the start of a
packet. My Logitech mouse seems to be passing an extra NULL pad
byte, and GPM does a similar thing here.
(gdk_fb_mouse_ms_open): changed error message to not say psaux, as
this is the ms mouse driver.
(gdk_fb_mouse_ms_packet): fix up button handling, which was
completely broken except for button1. It was checking the wrong
bit in the packet for the status of the right mouse button, and
wrongly assuming right == button2 rather than 3. I fixed that and
also added support for middle button (button2).
