A DataWindow object is made up of many controls (such as Columns, Text, Pictures, and Reports). In PowerBuilder scripts, the datatype of these controls is DWObject. Each DWObject has a set of properties according to its type. The syntax of a property expression allows you to address any of these properties.
A DataWindow property expression uses the Object property of the DataWindow control to access the DataWindow object. Following the Object property, you specify a control name and one or more properties.
The simple syntax is:
dwcontrol.Object.dwcontrolname.property
For example:
dw_1.Object.empname.Resizeable
For the full syntax, see “PowerBuilder syntax for DataWindow property expressions”.
About DataWindow data expressions Expressions that access data in a DataWindow object using dot notation use the Object and Data properties. These expressions are called data expressions (in contrast to property expressions); because of the intricate syntax for data expressions, they are described separately, in Chapter 4, “Accessing Data in Code.”
