Each sheet corresponds to a schematic drawing handled by a * SCH_SCREEN structure. A SCH_SCREEN structure contains drawings, and have * a filename to write it's data. Also a SCH_SCREEN display a sheet number * and the name of the sheet. * * In simple (and flat) hierarchies a sheet is linked to a SCH_SCREEN, * and a SCH_SCREEN is used by only one hierarchical sheet. * * In complex hierarchies the same SCH_SCREEN (and its data) is shared between * more than one sheet. Therefore subsheets (like subsheets in a SCH_SCREEN * shared by many sheets) can be also shared. So the same SCH_SCREEN must * handle different components references and parts selection depending on * which sheet is currently selected, and how a given subsheet is selected. * 2 sheets share the same SCH_SCREEN (the same drawings) if they have the * same filename. * * In KiCad each component and sheet receives (when created) an unique * identification called Time Stamp. So each sheet has 2 ids: its time stamp * (that cannot change) and its name ( that can be edited and therefore is * not reliable for strong identification). KiCad uses Time Stamp ( a unique * 32 bit id), to identify sheets in hierarchies. * A given sheet in a hierarchy is fully labeled by its path (or sheet path) * that is the list of time stamp found to access it through the hierarchy * the root sheet is /. All other sheets have a path like /1234ABCD or * /4567FEDC/AA2233DD/. This path can be displayed as human readable sheet * name like: / or /sheet1/include_sheet/ or /sheet2/include_sheet/ * * So to know for a given SCH_SCREEN (a given schematic drawings) we must: * 1) Handle all references possibilities. * 2) When acceded by a given selected sheet, display (update) the * corresponding references and sheet path * * The class SCH_SHEET_PATH handles paths used to access a sheet. The class * SCH_SHEET_LIST allows to handle the full (or partial) list of sheets and * their paths in a complex hierarchy. The class EDA_ScreenList allow to * handle the list of SCH_SCREEN. It is useful to clear or save data, * but is not suitable to handle the full complex hierarchy possibilities * (usable in flat and simple hierarchies). */ #include "sch_sheet.h" // SCH_SHEETS class wxFindReplaceData; class SCH_SCREEN; class SCH_MARKER; class SCH_ITEM; class SCH_REFERENCE_LIST; #define SHEET_NOT_FOUND -1 /** * Type SCH_MULTI_UNIT_REFERENCE_MAP * is used to create a map of reference designators for multi-unit parts. */ typedef std::map SCH_MULTI_UNIT_REFERENCE_MAP; /** * Class SCH_SHEET_PATH * * handles access to a stack of flattened #SCH_SHEET objects by way of a path for * creating a flattened schematic hierarchy. * *
