Methods Summary¶

`__init__`	Initializes to zero the x and y members.
`Get`	Get() . (x,y)
`GetCrossProduct`	Returns the cross product, where the products of the Y values of this point and `are` subtracted from the X products.
`GetDistance`	Returns the distance between this point and `pt` .
`GetDistanceSquare`	Returns the squared distance between this point and `pt` .
`GetDotProduct`	Returns the dot (i.e., scalar) product, where the products of the X and Y values of this point and `are` added.
`GetFloor`	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
`GetIM`	Returns an immutable representation of the `wx.Point2D` object, based on `namedtuple`.
`GetRounded`	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
`GetVectorAngle`	Returns the principal value of the arc tangent of the Y and X values, expressed in degrees.
`GetVectorLength`	Returns the hypotenuse, where the X and Y coordinates of the point represent the lengths of the base and height sides of a right triangle.
`Normalize`	Sets the vector length to 1.0, preserving the right angle and altering the X and Y values (which represent the base and height sides of a right triangle).
`SetVectorAngle`	Repositions the X and Y coordinates based on the provided angle’s degrees.
`SetVectorLength`	Sets the vector length to `length` , preserving the right angle and altering the X and Y values (which represent the base and height sides of a right triangle).
`__bool__`
`__getitem__`
`__len__`
`__nonzero__`
`__reduce__`
`__repr__`
`__setitem__`
`__str__`
`__ne__`	Returns the reflection (i.e., negation) of this point.

Methods¶

__init__(self, *args, **kw)¶

Overloaded Implementations:

__init__ (self)

Initializes to zero the x and y members.

Return type:: None

__init__ (self, x, y)

Initializes the point with the given coordinates.

Parameters:

x (wx.Double)
y (wx.Double)

Return type:

None

__init__ (self, pt)

Initializes the point from another point.

Parameters:: pt (Point2DDouble)
Return type:: None

__init__ (self, pt)

Initializes the point from another point.

Parameters:: pt (wx.Point)
Return type:: None

Get(self)¶

Get() . (x,y)

Return the x and y properties as a tuple.

Return type:: Any

GetCrossProduct(self, vec)¶

Returns the cross product, where the products of the Y values of this point and are subtracted from the X products.

This represents another vector that is at right angles to both points.

Parameters:: vec (Point2DDouble)
Return type:: float

GetDistance(self, pt)¶

Returns the distance between this point and pt .

Parameters:: pt (Point2DDouble)
Return type:: float

GetDistanceSquare(self, pt)¶

Returns the squared distance between this point and pt .

Parameters:: pt (Point2DDouble)
Return type:: float

GetDotProduct(self, vec)¶

Returns the dot (i.e., scalar) product, where the products of the X and Y values of this point and are added.

Parameters:: vec (Point2DDouble)
Return type:: float

GetFloor(self)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Return type:: wx.Point

GetIM(self)¶

Returns an immutable representation of the wx.Point2D object, based on namedtuple.

This new object is hashable and can be used as a dictionary key, be added to sets, etc. It can be converted back into a real wx.Point2D with a simple statement like this: obj = wx.Point2D(imObj).

GetRounded(self)¶

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Return type:: wx.Point

Returns the principal value of the arc tangent of the Y and X values, expressed in degrees.

Return type:: float

GetVectorLength(self)¶

Returns the hypotenuse, where the X and Y coordinates of the point represent the lengths of the base and height sides of a right triangle.

Return type:: float

Normalize(self)¶

Sets the vector length to 1.0, preserving the right angle and altering the X and Y values (which represent the base and height sides of a right triangle).

Return type:: None
