Shapes extend this class * to allow themselves to be manipulated. This class just represents * a graphical shape in the document and can be manipulated by some default * tools in this library. * * Due to the limited responsibility of this class, the extending object * can have any data backend and is responsible for painting itself. * * We strongly suggest that any extending class will use a Model View * Controller (MVC) design where the View part is all in this class, as well * as the one that inherits from this one. This allows the data that rests * in the model to be reused in different parts of the document. For example * by having two flake objects that show that same data. Or each showing a section of it. * * The KoShape data is completely in postscript-points (pt) (see KoUnit * for conversion methods to and from points). * This image will explain the real-world use of the shape and its options. *
* The Rotation center can be returned with absolutePosition() * *

Flake objects can be created in three ways: *

    *
  • a simple new KoDerivedFlake(), *
  • through an associated tool, *
  • through a factory *
* *

Shape interaction notifications

* We had several notification methods that allow your shape to be notified of changes in other * shapes positions or rotation etc. *
  1. The most general is KoShape::shapeChanged().
    * a virtual method that you can use to check various changed to your shape made by tools or otherwise.
    2. *
  2. for shape hierarchies the parent may receive a notification when a child was modified. * This is done though KoShapeContainerModel::childChanged()
    3. *
  3. any shape that is at a similar position as another shape there is collision detection. * You can register your shape to be sensitive to any changes like moving or whatever to * other shapes that intersect yours. * Such changes will then be notified to your shape using the method from (1) You should call * KoShape::setCollisionDetection(bool) to enable this. *
