Objects of type windowinstance are individual representations of windows created based on a windowclass.
Window instances contain controls, as defined in the sheetdata section of the windowclass definition, or dynamically constructed using the createControl function.
Window contents, i.e. the data present in the data field controls, is determined by the instance's association with the database tree. A window instance can be tied to a particular database tree node or it can be unbound (in which case getDatabaseNode returns nil). The node the window is bound to is called the window data source. The controls in the window will get their data from a node under the data source (see databasecontrol for details). The controls in an unbound window are unbound by default.
...
name (string)
The name of the control. If the control is a databasecontrol and the window has a data source, it will be bound to the corresponding node in the database.
