The PolygonShape
class shape is defined by a number of points
passed to the object’s constructor. It can be used to create new shapes
such as diamonds and triangles.

PolygonShape
(Shape)¶The PolygonShape
class shape is defined by a number of points
passed to the object’s constructor. It can be used to create new shapes
such as diamonds and triangles.
__init__
(self)¶Default class constructor
Does not follow above statement, should it? or is Create called automagically?
AddPolygonPoint
(self, pos)¶Add a control point after the given point.
pos – position of point
AttachmentIsValid
(self, attachment)¶Is attachment valid?
attachment – ???
CalculateBoundingBox
(self)¶Calculate the bounding box.
CalculatePolygonCentre
(self)¶Recalculates the centre of the polygon, and readjusts the point offsets accordingly. Necessary since the centre of the polygon is expected to be the real centre of the bounding box.
ClearPoints
(self)¶Clear the points.
Create
(self, the_points = None)¶Takes a list of wx.Points
or tuples; each point is an offset
from the centre.
DeletePolygonPoint
(self, pos)¶Delete the given control point.
pos – position of point
GetAttachmentPosition
(self, attachment, nth = 0, no_arcs = 1, line = None)¶Get attachment position.
attachment – the attachment ???
nth – get nth attachment ???
no_arcs – ???
line – ???
GetBoundingBoxMin
(self)¶Get minimum bounding box.
GetNumberOfAttachments
(self)¶Get number of attachments.
GetOriginalHeight
(self)¶Get the original height.
GetOriginalPoints
(self)¶Get the original points.
GetOriginalWidth
(self)¶Get the original width.
GetPerimeterPoint
(self, x1, y1, x2, y2)¶Get the perimeter point.
x1 – the x1 position
y1 – the y1 position
x2 – the x2 position
y2 – the y2 position
GetPoints
(self)¶Return the internal list of polygon vertices.
HitTest
(self, x, y)¶Hit text
x – the x position
y – the y position
MakeControlPoints
(self)¶Make control points.
OnDraw
(self, dc)¶The draw handler.
OnDrawOutline
(self, dc, x, y, w, h)¶The draw outline handler.
OnSizingBeginDragLeft
(self, pt, x, y, keys = 0, attachment = 0)¶The sizing begin drag left handler.
OnSizingDragLeft
(self, pt, draw, x, y, keys = 0, attachment = 0)¶The sizing drag left handler.
OnSizingEndDragLeft
(self, pt, x, y, keys = 0, attachment = 0)¶The sizing end drag left handler.
ResetControlPoints
(self)¶Reset control points.
Rotate
(self, x, y, theta)¶Rotate about the given axis by the given amount in radians.
x – the x position
y – the y position
theta – the theta
SetOriginalHeight
(self, h)¶Set the original height.
w – the height
SetOriginalWidth
(self, w)¶Set the original width.
w – the width
SetSize
(self, new_width, new_height, recursive = True)¶Set the size
new_width – the width
new_height – the height
recursive – not used
UpdateOriginalPoints
(self)¶If we’ve changed the shape, must make the original points match the working points with this function.
