class 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.


Methods



__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.

Parameters:pos – position of point


AttachmentIsValid(self, attachment)

Is attachment valid?

Parameters: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.

Parameters:pos – position of point


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

Get attachment position.

Parameters:
  • 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.

Parameters:
  • 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

Parameters:
  • 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.

Parameters:
  • x – the x position
  • y – the y position
  • theta – the theta


SetOriginalHeight(self, h)

Set the original height.

Parameters:w – the height


SetOriginalWidth(self, w)

Set the original width.

Parameters:w – the width


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

Set the size

Parameters:
  • 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.
