| def | wait(self) | [Inherited from _EventTrigger] | |
A composite that represents a group of shapes as a single drawable object. Objects are placed onto the layer relative to the coordinate system of the layer itself. The layer can then be placed onto a canvas (or even onto another layer).
| def __contains__ | ( | self, | ||
| obj | ||||
| ) | [inherited] |
Return True if obj is currently in the container; False otherwise.
| def __init__ | ( | self | ) |
Construct a new Layer instance. The layer is initially empty. The reference point of that layer is initially the origin in its own coordinate system, (0,0).
| def add | ( | self, | ||
| drawable | ||||
| ) |
Add the Drawable object to the layer.
| def addHandler | ( | self, | ||
| handler | ||||
| ) | [inherited] |
Register an EventHandler instance with this object.
| def adjustReference | ( | self, | ||
| dx, | ||||
| dy | ||||
| ) | [inherited] |
Move the local reference point relative to its current position. Note that the object is not moved at all.
| def clear | ( | self | ) | [inherited] |
Remove all objects from the container.
| def clone | ( | self | ) | [inherited] |
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 | ||||
| ) | [inherited] |
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 getContents | ( | self | ) | [inherited] |
Return the contents of the container, sorted by depth.
| def getDepth | ( | self | ) | [inherited] |
Return the depth of the object.
| def getReferencePoint | ( | self | ) | [inherited] |
Return a copy of the current reference point. Note that mutating that copy has no effect on the Drawable object.
| def move | ( | self, | ||
| dx, | ||||
| dy | ||||
| ) | [inherited] |
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, | ||
| x, | ||||
| y | ||||
| ) | [inherited] |
Move the object to align its reference point with (x,y)
| def remove | ( | self, | ||
| drawable | ||||
| ) |
Remove the Drawable object from the layer. A ValueError is raised if the drawable is not currently in the layer.
| def removeHandler | ( | self, | ||
| handler | ||||
| ) | [inherited] |
Unregister an EventHandler instance from this object.
| def rotate | ( | self, | ||
| angle | ||||
| ) | [inherited] |
Rotate the object around its current reference point. angle number of degrees of clockwise rotation
Reimplemented in Text.
| def scale | ( | self, | ||
| factor | ||||
| ) | [inherited] |
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, | ||
| depth | ||||
| ) | [inherited] |
Set the depth of the object. Objects with a higher depth will be rendered behind those with lower depths.
| def shear | ( | self, | ||
| shear, | ||||
angle = 0 | ||||
| ) | [inherited] |
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, | ||
| xFactor, | ||||
| yFactor, | ||||
angle = 0 | ||||
| ) | [inherited] |
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 along.
| 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.
