Gnocl -the Tcl/Gtk Bindings

The current basis of the cget function for widgets is based upon code written over 20yrs ago and, whilst it works reasonably well for the simple setting of gtk widget properties, support for more complex custom options is hit and miss.   typedef struct GnoclOption_ {     const char *optName;       enum GnoclOptionType type;     const char *propName;     gnoclOptFunc *func;     const char *args;     const char *description;     const char *values;      enum GnoclOptionStatus status;     union {         gboolean b;         gint     i;         gdouble  d;           gchar    *str;           Tcl_Obj  *obj;           } val; } GnoclOption;   With the recent updating of the C sources which includes an expansion of the GnoclOption structure to accommodate documentation support, it well worth reviewing the way in which widget functions handle the return of options. Rather than treating the retrieval of properties set by a function as the final call, perhaps it should be prioritized.

     static char *options[] = {         "-opt1", "-opt2", "-opt3",NULL     }; static enum  optsIdx {     opt1Idx, opt2Idx, opt3Idx     };  gint idx; /* obtain idx from an array of strings */ Tcl_GetIndexFromObj ( interp, objv[1], options, "option", TCL_EXACT, &idx ); /* obtain idx from array of structures, not an array of strings */ Tcl_GetIndexFromObjStruct ( interp, objv[1], ( char ** ) &commands[0].cmdName, sizeof ( GnoclCommand ), "command", TCL_EXACT, &idx );
