Syntax - Window objects

Windows and window objects are created by instructions of the form:

Widget(objectname~aliasName, flags, x, y, w, h, static text, bitmap)

described.

"Widget" stands for one of the identifiers:

Car Button Checkbox combo box Composite ContextMenuList Control Date DigitalTime DigitalTimer Document Enumeration FormattedString

Fraction Group Header Import (with easy other syntax) Integer Item Menu MLOleBox MultipleString MultipleText Notebook Numeric ObjectCombobox TreeList

ObjectListView ObjectTree OleBox Percent Picture Prompt Radio Status bar String Text Time Toolbar Window

Window objects have a parent-child relationship with each other - in the script this is expressed by including child objects following the parent object in { and }(example). Action lists follow immediately - before a block of child objects - the window object to which they belong(example).

The name of a window object

Widget(objectName~aliasName, ...)

is required if a statement is to refer to this window object, whereby the window object must be uniquely defined by a tuple of the name of the parent window and its own name. Furthermore, a name of the form

Class::access expression

establishes a relationship between the window object and objects of the model class mentioned, i.e. the data exchange in the direction of model - surface and vice versa is described. Access expression is in the simplest case the name of a data member, but you can also navigate through the objects. If an instruction refers to the window object, only the access expression (i.e. the substring after the scope operator ::) is used as name. Optionally, a further name (aliasName) can be assigned, which can be used in the corresponding statements just like the object name. For long access expressions, this allows a more convenient spelling, and ambiguities can be resolved with the alias name (e.g. if two instances of the same class are to be displayed on one window).
