CAN-SET function

Returns a logical value indicating whether you can set a specified attribute for a specified widget.

Syntax

CAN-SET ( handle , attribute-name )

handle

An expression that evaluates to a handle. The handle must refer to a valid widget.

attribute-name

An expression that evaluates to a character-string value. The contents of the string must be an attribute name. For more information on attributes, see the Handle Attributes and Methods Reference.

Notes

For a field-level widget, the CAN-SET function always returns TRUE for the FRAME attribute; however, you can set the frame attribute only if the widget is dynamic. Therefore, before setting the FRAME attribute for a widget, you can test that the operation is valid with a statement similar to the following:

IF CAN-SET(my-handle, "FRAME") AND my-handle:DYNAMIC THEN
my-handle:FRAME = frame-handle.

For SpeedScript, use with buffer-field, buffer-object, buffer, and query-object handles.
