IsClosed

IsClosed() -> bool

Check for closed path, it mean that first point is same as last point

Returns:

• bool –

  True when path is closed, otherwise false.

IsItPossibleToAddElement

IsItPossibleToAddElement(pGeometry_object: object) -> bool

Check if the geometry can be added into path Path2D

Parameters:

• pGeometry_object (object) –

  Pointer to geometry to check

IsValid

IsValid() -> bool

Validity check

\warning Path doesn't have to be closed to be valid, you have to check this extra

Parameters:

• pGeometry_object (object) –

  Pointer to geometry to check

SetEndPoint

SetEndPoint(endpoint: Point2D)

Set end (last) point of the path

Parameters:

• endpoint (Point2D) –

  E point

Returns:

• –

  none

SetStartPoint

SetStartPoint(startpoint: Point2D)

Set start (first) point of the path

Parameters:

• startpoint (Point2D) –

  Start point

Returns:

__eq__

__eq__(path: Path2D) -> object

Comparison of paths without tolerance.

Be careful, this method work without tolerance!

Parameters:

  Compared path.

Returns:

• object –

  True when paths are equal, otherwise false.

__iadd__ overloaded

__iadd__(element: Path2D) -> Path2D

Append operator

Parameters:

Append operator

Parameters:

• element (Line2D) –

  Element which will be appended
