embodied in the class
hierarchy
The inheritance depicted in the class hierarchy diagram can be summarized
as follows:
Logical classes
The AnyWin, Control, and MoveableWin classes are logical (virtual) classes
that do not correspond to any actual GUI objects, but instead define methods
common to the classes that derive from them. This means that SilkTest never
records a declaration that has one of these classes.
CursorClass,
ClipboardClass, and
AgentClass
There are three classes that are not part of the AnyWin class hierarchy,
because they define methods for objects that are not windows:
·
CursorClass, which defines the three methods you can use on the cursor:
GetPosition, GetType, and Wait.
·
ClipboardClass, which defines the two methods you can use on the
system clipboard: GetText and SetText.

CustomWin

Assigned to objects that do not correspond to any class
in the built-in class hierarchy. Because the CustomWin
class derives from the AnyWin class, you can use the
primitive methods of the AnyWin class, like PressKeys,
to define higher level actions to perform on your
custom GUI objects.
