MWAPI - External Resources

Draft MDC Standard

☞

3.3.6 External Resources

External resources provided by the implementor, by the underlying windowing platform, or by another source, are identified by extresource.

    extresource::= expr V │
│
│		 F,fileid
R,resourceid
implementationvalue		 │
│
│

fileid and resourceid are platform-dependent file and resource identifiers, respectively. The formats of fileids and resourceids are unspecified.

In addition to external sources for symbols, a number of symbol types are specified by the MWAPI.

    symbol::= │
│
│
│
│
│		 extresource
expr V │
│
│
│
│		 M,ERROR
M,INFO
M,QUEST
M,WARN		 │
│
│
│
│
│
│
│
│
│
│

symbol values of "M,ERROR", "M,INFO", "M,QUEST", and "M,WARN" specify symbols that identify error, information, question, and warning situations, respectively. If the underlying windowing platform provides symbols for these situations, they are used. Otherwise, symbols are provided by the MWAPI. extresource enables use of other symbols not specified by the MWAPI.

    marker::= │
│
│
│
│		 extresource
expr V │
│
│
│		 M,BULLET
M,CHECK
M,DIAMOND		 │
│
│
│
│
│
│
│
│

marker values of "M,BULLET", "M,CHECK", and "M,DIAMOND" specify menu choice markers shaped like bullets, check marks, and diamonds, respectively. If the underlying windowing platform provides markers for these situations, they are used. Otherwise, markers are provided by the MWAPI. extresource enables use of other markers not specified by the MWAPI.

    ptype::= │
│
│
│
│
│		 extresource
expr V │
│
│
│
│		 M,CROSS
M,IBEAM
M,WAIT
M,POINTER		 │
│
│
│
│
│
│
│
│
│
│

ptype values of "M,CROSS", "M,IBEAM", "M,WAIT", and "M,POINTER" specify pointer appearance that indicates cross-hairs, an I-beam, waiting, and standard pointer, respectively. If the underlying windowing platform provides symbols for these situations, they are used. Otherwise, symbols are provided by the MWAPI. extresource enables use of other symbols not specified by the MWAPI.
