Draws a set of points
If Points is a sequence of tuples: Points[N][0] is the xcoordinate of point N and Points[N][1] is the ycoordinate.
If Points is a NumPy array: Points[N,0] is the xcoordinate of point N and Points[N,1] is the ycoordinate for arrays.
Each point will be drawn the same color and Diameter. The Diameter is in screen pixels, not world coordinates.
The hittest code does not distinguish between the points, you will only know that one of the points got hit, not which one. You can use PointSet.FindClosestPoint(WorldPoint) to find out which one
In the case of points, the HitLineWidth is used as diameter.
wx.lib.floatcanvas.FCObjects.ColorOnlyMixin
, wx.lib.floatcanvas.FCObjects.DrawObject
, wx.lib.floatcanvas.FCObjects.PointsObjectMixin
Default class constructor. 

Returns the index of the closest point to the point, XY, given 

Sets the diameter 
PointSet
(PointsObjectMixin, ColorOnlyMixin, DrawObject)¶Draws a set of points
If Points is a sequence of tuples: Points[N][0] is the xcoordinate of point N and Points[N][1] is the ycoordinate.

__init__
(self, Points, Color="Black", Diameter=1, InForeground=False)¶Default class constructor.
Points – takes a 2tuple, or a (2,) NumPy array of point coordinates
Color – see SetColor
Diameter (integer) – the points diameter
InForeground (boolean) – should object be in foreground
DrawD2
(self, dc, Points)¶FindClosestPoint
(self, XY)¶Returns the index of the closest point to the point, XY, given in World coordinates. It’s essentially random which you get if there are more than one that are the same.
This can be used to figure out which point got hit in a mouse binding callback, for instance. It’s a lot faster that using a lot of separate points.
XY – the (x,y) coordinates of the point to look for, it takes a 2tuple or (2,) numpy array in World coordinates
SetDiameter
(self, Diameter)¶Sets the diameter
Diameter (integer) – the points diameter
