Widget Handles
Progress assigns every static or dynamic widget a handle value once it is created. This handle serves a different purpose, depending on whether the widget is static or dynamic:
- For a static widget, the handle provides a unique reference to the widget besides the widget name. The widget name, by itself, can be ambiguous if the widget is specified in more than one container widget. Progress resolves this ambiguity differently depending on the widget. However, the handle to a widget is always unambiguous.
- For a dynamic widget, it provides the only means to reference and manage the widget that you create.
You generally store widget handle values in variables or fields defined with the WIDGET–HANDLE data type. For more information on widget handles and how to use them, see the "Static Versus Dynamic Widgets" section.
