|
// struct id : this structure is used to identify PCB design elements
|
|
// such as instances of parts or nets, and their subelements
|
|
// Each element will have its own id.
|
|
// An id is attached to each item of the Display List so that it can
|
|
// be linked back to the PCB design element which drew it.
|
|
// These are mainly used to identify items selected by clicking the mouse
|
|
//
|
|
// In general:
|
|
// id.type = type of PCB element (e.g. part, net, text)
|
|
// id.st = subelement type (e.g. part pad, net connection)
|
|
// id.i = subelement index (zero-based)
|
|
// id.sst = subelement of subelement (e.g. net connection segment)
|
|
// id.ii = subsubelement index (zero-based)
|
|
//
|
|
// For example, the id for segment 0 of connection 4 of net 12 would be
|
|
// id = { ID_NET, 12, ID_CONNECT, 4, ID_SEG, 0 };
|
|
//
