Detailed Description

"Standard" polygon editing behavior for EDA_SHAPE polygons.

As long as updating the EDA_SHAPE's SHAPE_POLY_SET in-place is enough, this will do the job.

virtual OPT_VECTOR2I POINT_EDIT_BEHAVIOR::Get45DegreeConstrainer	(	const EDIT_POINT &	aEditedPoint,
		EDIT_POINTS &	aPoints
	)		const

inlinevirtualinherited

Get the 45-degree constrainer for the item, when the given point is moved.

Return std::nullopt if not, and the caller can decide.

If you want to actively disable constraining, return the aEditedPoint position.

◆ MakePoints()

void POLYGON_POINT_EDIT_BEHAVIOR::MakePoints ( EDIT_POINTS & aPoints )

inlineoverridevirtualinherited

Construct the initial set of edit points for the item and append to the given list.

Parameters

aPoints The list of edit points to fill.

Implements POINT_EDIT_BEHAVIOR.

◆ UpdateItem()

void POLYGON_POINT_EDIT_BEHAVIOR::UpdateItem	(	const EDIT_POINT &	aEditedPoint,
		EDIT_POINTS &	aPoints,
		COMMIT &	aCommit,
		std::vector< EDA_ITEM * > &	aUpdatedItems
	)

inlineoverridevirtualinherited

Update the item with the new positions of the edit points.

This method should all commit and add to the update list anything that is NOT the parent item of the EDIT_POINTs. For example, connected lines, parent tables, etc. The item itself is already handled (most behaviors don't need more than that).

Parameters

aEditedPoint	The point that was dragged. You can use this to check by address which point to update.
aPoints	The new positions of the edit points.
aCommit	The commit object to use to modify the item.
aUpdatedItems	The list of items that were updated by the edit (not only the item that was being edited, but also any other items that were affected, e.g. by being conneted to the edited item).

Implements POINT_EDIT_BEHAVIOR.

Reimplemented in ZONE_POINT_EDIT_BEHAVIOR.
