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.
