Defining a URL-based web component in forms

Adding a WEBCOMPONENT to the form file

To define a URL-based web component field, add a form field with the WEBCOMPONENT item type, without the COMPONENTTYPE attribute:

WEBCOMPONENT f001 = FORMONLY.mymap;

A web component field is typically defined with the FORMONLY prefix, as the data for the field is rarely stored in a database column.

The field type (and its corresponding program variable) must be a character string type. Consider using the STRING type to avoid any size limitation for the URL specification.

Sizing policy for web component fields

Web components are usually complex widgets displaying detailed information, such as charts, graphs, or calendars, which are generally resizeable. Use the appropriate form item attributes to get the expected layout and behavior. For more details, see Controlling the web component layout.

Example

LAYOUT
GRID
{
[wc                       ]
[                         ]
[                         ]
[                         ]
[                         ]
}
END
END
