How to use pktdef.h:
|
||
|
|
||
|
1. Include wintab.h
|
||
|
2. if using just one packet format:
|
||
|
a. Define PACKETDATA and PACKETMODE as or'ed combinations of WTPKT bits
|
||
|
(use the PK_* identifiers).
|
||
|
b. Include pktdef.h.
|
||
|
c. The generated structure typedef will be called PACKET. Use PACKETDATA
|
||
|
and PACKETMODE to fill in the LOGCONTEXT structure.
|
||
|
3. If using multiple packet formats, for each one:
|
||
|
a. Define PACKETNAME. Its text value will be a prefix for this packet's
|
||
|
parameters and names.
|
||
|
b. Define <PACKETNAME>PACKETDATA and <PACKETNAME>PACKETMODE similar to
|
||
|
2.a. above.
|
||
|
c. Include pktdef.h.
|
||
|
d. The generated structure typedef will be called
|
||
|
<PACKETNAME>PACKET. Compare with 2.c. above and example #2 below.
|
||
|
4. If using extension packet data, do the following additional steps
|
||
|
for each extension:
|
||
|
a. Before including pktdef.h, define <PACKETNAME>PACKET<EXTENSION>
|
||
|
as either PKEXT_ABSOLUTE or PKEXT_RELATIVE.
|
||
|
b. The generated structure typedef will contain a field for the
|
||
|
extension data.
|
||
|
c. Scan the WTI_EXTENSION categories to find the extension's
|
||
|
packet mask bit.
|
||
|
d. OR the packet mask bit with <PACKETNAME>PACKETDATA and use the
|
||
|
result in the lcPktData field of the LOGCONTEXT structure.
|
||
|
e. If <PACKETNAME>PACKET<EXTENSION> was PKEXT_RELATIVE, OR the
|
||
|
packet mask bit with <PACKETNAME>PACKETMODE and use the result
|
||
|
in the lcPktMode field of the LOGCONTEXT structure.
|
||
|
|
||
|
|
||
|
Example #1. -- single packet format
|
||
|
|
||
|
#include <wintab.h>
|
||
|
#define PACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/
|
||
|
#define PACKETMODE PK_BUTTONS /@ buttons relative mode @/
|
||
|
#include <pktdef.h>
|
||
|
...
|
||
|
lc.lcPktData = PACKETDATA;
|
||
|
lc.lcPktMode = PACKETMODE;
|
||
|
|
||
|
Example #2. -- multiple formats
|
||
|
|
||
|
#include <wintab.h>
|
||
|
#define PACKETNAME MOE
|
||
|
#define MOEPACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/
|
||
|
#define MOEPACKETMODE PK_BUTTONS /@ buttons relative mode @/
|
||
|
#include <pktdef.h>
|
||
|
#define PACKETNAME LARRY
|
||
|
#define LARRYPACKETDATA PK_Y | PK_Z | PK_BUTTONS /@ y, z, buttons @/
|
||
|
#define LARRYPACKETMODE PK_BUTTONS /@ buttons relative mode @/
|
||
|
#include <pktdef.h>
|
||
|
#define PACKETNAME CURLY
|
||
|
#define CURLYPACKETDATA PK_X | PK_Z | PK_BUTTONS /@ x, z, buttons @/
|
||
|
#define CURLYPACKETMODE PK_BUTTONS /@ buttons relative mode @/
|
||
|
#include <pktdef.h>
|
||
|
...
|
||
|
lcMOE.lcPktData = MOEPACKETDATA;
|
||
|
lcMOE.lcPktMode = MOEPACKETMODE;
|
||
|
...
|
||
|
lcLARRY.lcPktData = LARRYPACKETDATA;
|
||
|
lcLARRY.lcPktMode = LARRYPACKETMODE;
|
||
|
...
|
||
|
lcCURLY.lcPktData = CURLYPACKETDATA;
|
||
|
lcCURLY.lcPktMode = CURLYPACKETMODE;
|
||
|
|
||
|
Example #3. -- extension packet data "XFOO".
|
||
|
|
||
|
#include <wintab.h>
|
||
|
#define PACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/
|
||
|
#define PACKETMODE PK_BUTTONS /@ buttons relative mode @/
|
||
|
#define PACKETXFOO PKEXT_ABSOLUTE /@ XFOO absolute mode @/
|
||

#include <pktdef.h>
