Release 10.1A: OpenEdge Development:
Progress 4GL Reference

Widget method references

To reference a method, use the following syntax:

{ widget-name-reference | handle} :method-name ( [ parameter-list ] ) [ IN container-widget-name ]

A widget-name-reference is a name reference to a static widget. A handle is a widget handle, procedure handle, or system handle reference. A container-widget-name is a name reference to a static container widget for the widget-name-reference or a browse widget. You need it only if widget-name-reference is ambiguous. For more information on method references, see the chapter on widgets and handles in OpenEdge Development: Progress 4GL Handbook .

To execute a method, you can assign the return value to a variable, reference the method in an expression, or invoke the method as a statement, ignoring the return value. The following example executes the ADD-FIRST( ) method for a selection list (Select-1) in two different ways-assigning the return value to a logical variable (methRtn) and invoking it directly:

methRtn = Select-1:ADD-FIRST("BLUE"). Select-1:ADD-FIRST("GREEN").

The methods in this section are listed alphabetically by name. Each method entry defines the data type of the return value and describes any required parameters.
