Functions

Function Documentation

AlignSchematicItemsToGrid()

void AlignSchematicItemsToGrid	(	SCH_SCREEN *	aScreen,
		const std::vector< EDA_ITEM * > &	aItems,
		EE_GRID_HELPER &	aGrid,
		GRID_HELPER_GRIDS	aSelectionGrid,
		const SCH_ALIGNMENT_CALLBACKS &	aCallbacks )

Align a set of schematic items to the grid.

This function implements the core alignment logic used by the "Align Items to Grid" action. It handles different item types appropriately: lines align their endpoints, sheets align their corners and resize, sheet pins align to grid while maintaining connectivity with their connected wires, etc.

Parameters

aScreen	The schematic screen containing the items
aItems	The items to align (typically the current selection)
aGrid	The grid helper used for alignment calculations
aSelectionGrid	The grid type to use for alignment
aCallbacks	Callbacks for moving items and getting connected drag items

MoveSchematicItem()

void MoveSchematicItem	(	EDA_ITEM *	aItem,
		const VECTOR2I &	aDelta )

Move a schematic item by a delta.

This function implements the move logic for different item types, matching the behavior of SCH_MOVE_TOOL::moveItem in DRAG mode:

• SCH_LINE_T: Moves only flagged endpoints (STARTPOINT/ENDPOINT)
• SCH_SHEET_PIN_T: Uses SetStoredPos + ConstrainOnEdge
• Other items: Calls Move()

Parameters

aItem	The item to move
aDelta	The movement delta
