## 5 Free Objects

In some applications the standard object classes as provided by the Forms Library may not be enough for your task. There are three ways of solving this problem. First of all, the application program can also open its own window or use a canvas (the preferred way) in which it does interaction with the user). A second way is to add your own object classes (see Part IV). This is especially useful when your new type of objects is of general use.

The third way is to add free objects to your form. Free objects are objects for which the application program handles the drawing and interaction. This chapter will give all the details needed to design and use free objects.
