class PolygonShape(Shape)

A PolygonShape’s 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.

Methods

---

__init__(self)

---

AddPolygonPoint(self, pos)

Add a control point after the given point.

---

AttachmentIsValid(self, attachment)

---

CalculateBoundingBox(self)

---

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)

---

Create(self, the_points = None)

Takes a list of wx.RealPoints or tuples; each point is an offset from the centre.

---

DeletePolygonPoint(self, pos)

Delete the given control point.

---

GetAttachmentPosition(self, attachment, nth = 0, no_arcs = 1, line = None)

---

GetBoundingBoxMin(self)

---

GetNumberOfAttachments(self)

---

GetOriginalHeight(self)

---

GetOriginalPoints(self)

---

GetOriginalWidth(self)

---

GetPerimeterPoint(self, x1, y1, x2, y2)

---

GetPoints(self)

Return the internal list of polygon vertices.

---

HitTest(self, x, y)

---

MakeControlPoints(self)

---

OnDraw(self, dc)

---

OnDrawOutline(self, dc, x, y, w, h)

---

OnSizingBeginDragLeft(self, pt, x, y, keys = 0, attachment = 0)

---

OnSizingDragLeft(self, pt, draw, x, y, keys = 0, attachment = 0)

---

OnSizingEndDragLeft(self, pt, x, y, keys = 0, attachment = 0)

---

ResetControlPoints(self)

---

Rotate(self, x, y, theta)

---

SetOriginalHeight(self, h)

---

SetOriginalWidth(self, w)

---

SetSize(self, new_width, new_height, recursive = True)

---

UpdateOriginalPoints(self)

If we’ve changed the shape, must make the original points match the working points with this function.
