| /*********************************************************************** |
| * 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> |
| * ... |
| * UINT ScanExts(UINT wTag) |
| * { |
| * UINT i; |
| * UINT wScanTag; |
| * |
| * /@ scan for wTag's info category. @/ |
| * for (i = 0; WTInfo(WTI_EXTENSIONS + i, EXT_TAG, &wScanTag); i++) { |
| * if (wTag == wScanTag) { |
| * /@ return category offset from WTI_EXTENSIONS. @/ |
| * return i; |
| * } |
| * } |
| * /@ return error code. @/ |
| * return 0xFFFF; |
| * } |
| * ... |
| * lc.lcPktData = PACKETDATA; |
| * lc.lcPktMode = PACKETMODE; |
| * #ifdef PACKETXFOO |
| * categoryXFOO = ScanExts(WTX_XFOO); |
| * WTInfo(WTI_EXTENSIONS + categoryXFOO, EXT_MASK, &maskXFOO); |
| * lc.lcPktData |= maskXFOO; |
| * #if PACKETXFOO == PKEXT_RELATIVE |
| * lc.lcPktMode |= maskXFOO; |
| * #endif |
| * #endif |
| * WTOpen(hWnd, &lc, TRUE); |
