Member Function Documentation

def __init__ (   self,
  reference = None 

Create a Drawable instance.

referencePoint  local reference point for scaling, rotating and flipping
              (default Point(0,0) )

Reimplemented in Shape, FillableShape, Path, and Polygon.

def addHandler (   self,
) [inherited]

Register an EventHandler instance with this object.

def adjustReference (   self,

Move the local reference point relative to its current position.

Note that the object is not moved at all.

def clone (   self  ) 

Return a duplicate of the drawable object.

Note that the duplicate is not automatically added to any
canvases or layers, even if original is currently so.

def flip (   self,
  angle = 0 

Flip the object reflected about its current reference point.

By default the flip is a left-to-right flip with a vertical axis of symmetry.

angle     a clockwise rotation of the axis of symmetry away from vertical

def getDepth (   self  ) 

Return the depth of the object.

def getReferencePoint (   self  ) 

Return a copy of the current reference point.

Note that mutating that copy has no effect on the Drawable object.

def move (   self,

Move the object dx units along X-axis and dy units along Y-axis.

For the default coordinate system, positive dx is rightward and
negative is leftward; positive dy is downard and negative is upward.

def moveTo (   self,

Move the object to align its reference point with (x,y)

def removeHandler (   self,
) [inherited]

Unregister an EventHandler instance from this object.

def rotate (   self,

Rotate the object around its current reference point.

angle  number of degrees of clockwise rotation

Reimplemented in Text.

def scale (   self,

Scale the object relative to its current reference point.

factor      scale is multiplied by this number (must be positive)

Reimplemented in Text.

def setDepth (   self,

Set the depth of the object.

Objects with a higher depth will be rendered behind those with lower depths.

def shear (   self,
  angle = 0 

Shear the object relative to its current reference point.

By default, points with the same y-coordinate as the reference point are left
unchanged.  A point d units above the reference point is shifted d * shear
units to the right.  The optional angle parameter rotates the axis
that the shearing occurs along.

angle      clockwise angle for shear

def stretch (   self,
  angle = 0 

Stretch the shape in mutltiple direction.

By default the x-axis is scaled by a factor of xFactor and the
y-axis is scaled by a factor of yFactor.  The optional
parameter rotates the directions that the streching is performed

def wait (   self  )  [inherited]

Wait for an event to occur.

When an event occurs, an Event instance is returned
with information about what has happened.
