Detailed Description

Handle access to a stack of flattened SCH_SHEET objects by way of a path for creating a flattened schematic hierarchy.

The SCH_SHEET objects are stored in a list from first (usually the root sheet) to a given sheet in last position. The last sheet is usually the sheet we want to select or reach (which is what the function Last() returns). Others sheets constitute the "path" from the first to the last sheet.

AppendMultiUnitSymbol()

void SCH_SHEET_PATH::AppendMultiUnitSymbol	(	SCH_MULTI_UNIT_REFERENCE_MAP &	aRefList,
		SCH_SYMBOL *	aSymbol,
		bool	aIncludePowerSymbols = true
	)		const

Append a SCH_REFERENCE_LIST object to aRefList based on aSymbol, storing same-reference set of multi-unit parts together.

The map key for each element will be the reference designator.

Parameters

aRefList	Map of reference designators to reference lists
aSymbol	A symbol to add to aRefList
aIncludePowerSymbols	Set to false to only get normal symbols.

Definition at line 351 of file sch_sheet_path.cpp.

Append a SCH_REFERENCE object to aReferences based on aSymbol.

Parameters

aReferences	List of references to populate.
aSymbol	A symbol to add to aReferences
aIncludePowerSymbols	set to false to only get normal symbols.

MakeFilePathRelativeToParentSheet()

void SCH_SHEET_PATH::MakeFilePathRelativeToParentSheet

Make the sheet file name relative to its parent sheet.

This should only be called when changing the parent sheet path such performing a save as or a new schematic without a project in stand alone mode. The sheet file name is only made relative if the current file name is relative. Absolute sheet file name paths are a user choice so do not change them.

Sheet file name paths are set according to the following criteria:

• If the sheet file name path is in the same as the parent sheet file name path, set the sheet file name to just the file name and extension with no path.
• If the sheet file name path can be made relative to the parent sheet file name path, set the sheet file name using the relative path.
• If the sheet file name path cannot be converted to a relative path, then fall back to the absolute file name path.

SetPageNumber()

void SCH_SHEET_PATH::SetPageNumber

Set the sheet instance user definable page number.

Note

User definable page numbers can be any string devoid of white space characters.

SetVirtualPageNumber()

void SCH_SHEET_PATH::SetVirtualPageNumber ( int  aPageNumber )

inline

Set the sheet instance virtual page number.

Virtual page numbers are incremental integers set automatically when the sheet path hierarchy is created (

See also

SCH_SHEET_LIST::BuildSheetList). The virtual page numbering is ordered by the X and Y position of the sheet in a schematic which mimics the page numbering code prior to the addition of actual user definable page numbers. Virtual page numbers should only be use when annotating schematics.

TestForRecursion()

bool SCH_SHEET_PATH::TestForRecursion	(	const wxString &	aSrcFileName,
		const wxString &	aDestFileName
	)

Test the SCH_SHEET_PATH file names to check adding the sheet stored in the file aSrcFileName to the sheet stored in file aDestFileName will cause a sheet path recursion.

Parameters

aSrcFileName	is the source file name of the sheet add to aDestFileName.
aDestFileName	is the file name of the destination sheet for aSrcFileName.

Returns

true if aFileName will cause recursion in the sheet path. Otherwise false.

Todo:

Store sheet file names with full path, either relative to project path or absolute path. The current design always assumes subsheet files are located in the project folder which may or may not be desirable.
