| 13 How to use pktdef.h: | |
| 14 | |
| 15 1. Include wintab.h | |
| 16 2. if using just one packet format: | |
| 17 a. Define PACKETDATA and PACKETMODE as or'ed combinations of WTPKT bits | |
| 18 (use the PK_* identifiers). | |
| 19 b. Include pktdef.h. | |
| 20 c. The generated structure typedef will be called PACKET. Use PACKETDATA | |
| 21 and PACKETMODE to fill in the LOGCONTEXT structure. | |
| 22 3. If using multiple packet formats, for each one: | |
| 23 a. Define PACKETNAME. Its text value will be a prefix for this packet's | |
| 24 parameters and names. | |
| 25 b. Define <PACKETNAME>PACKETDATA and <PACKETNAME>PACKETMODE similar to | |
| 26 2.a. above. | |
| 27 c. Include pktdef.h. | |
| 28 d. The generated structure typedef will be called | |
| 29 <PACKETNAME>PACKET. Compare with 2.c. above and example #2 below. | |
| 30 4. If using extension packet data, do the following additional steps | |
| 31 for each extension: | |
| 32 a. Before including pktdef.h, define <PACKETNAME>PACKET<EXTENSION> | |
| 33 as either PKEXT_ABSOLUTE or PKEXT_RELATIVE. | |
| 34 b. The generated structure typedef will contain a field for the | |
| 35 extension data. | |
| 36 c. Scan the WTI_EXTENSION categories to find the extension's | |
| 37 packet mask bit. | |
| 38 d. OR the packet mask bit with <PACKETNAME>PACKETDATA and use the | |
| 39 result in the lcPktData field of the LOGCONTEXT structure. | |
| 40 e. If <PACKETNAME>PACKET<EXTENSION> was PKEXT_RELATIVE, OR the | |
| 41 packet mask bit with <PACKETNAME>PACKETMODE and use the result | |
| 42 in the lcPktMode field of the LOGCONTEXT structure. | |
| 43 | |
| 44 | |
| 45 Example #1. -- single packet format | |
| 46 | |
| 47 #include <wintab.h> | |
| 48 #define PACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/ | |
| 49 #define PACKETMODE PK_BUTTONS /@ buttons relative mode @/ | |
| 50 #include <pktdef.h> | |
| 51 ... | |
| 52 lc.lcPktData = PACKETDATA; | |
| 53 lc.lcPktMode = PACKETMODE; | |
| 54 | |
| 55 Example #2. -- multiple formats | |
| 56 | |
| 57 #include <wintab.h> | |
| 58 #define PACKETNAME MOE | |
| 59 #define MOEPACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/ | |
| 60 #define MOEPACKETMODE PK_BUTTONS /@ buttons relative mode @/ | |
| 61 #include <pktdef.h> | |

| 64 #define LARRYPACKETMODE PK_BUTTONS /@ buttons relative mode @/ | |
| 65 #include <pktdef.h> | |
| 66 #define PACKETNAME CURLY | |
| 67 #define CURLYPACKETDATA PK_X | PK_Z | PK_BUTTONS /@ x, z, buttons @/ | |
| 68 #define CURLYPACKETMODE PK_BUTTONS /@ buttons relative mode @/ | |
| 69 #include <pktdef.h> | |
| 70 ... | |
| 71 lcMOE.lcPktData = MOEPACKETDATA; | |
| 72 lcMOE.lcPktMode = MOEPACKETMODE; | |
| 73 ... | |
| 74 lcLARRY.lcPktData = LARRYPACKETDATA; | |
| 75 lcLARRY.lcPktMode = LARRYPACKETMODE; | |
| 76 ... | |
| 77 lcCURLY.lcPktData = CURLYPACKETDATA; | |
| 78 lcCURLY.lcPktMode = CURLYPACKETMODE; | |
| 79 | |
| 80 Example #3. -- extension packet data "XFOO". | |
| 81 | |
| 82 #include <wintab.h> | |
| 83 #define PACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/ | |
| 84 #define PACKETMODE PK_BUTTONS /@ buttons relative mode @/ | |
| 85 #define PACKETXFOO PKEXT_ABSOLUTE /@ XFOO absolute mode @/ | |
| 86 #include <pktdef.h> | |
