allow-component-overlap

Arguments: configuration

Returns the value of the allow-component-overlap property of configuration.

The current configuration is the value of

(configuration *system*)

so

(allow-component-overlap (configuration *system*))

returns the current value and

(setf (allow-component-overlap (configuration *system*)) <new value>)

sets it.

See configuration and *system*.

If this property is true, controls on a dialog can overlap one another (so one partially covers another). If the property value is nil, controls cannot be placed so they overlap while designing a form with the Integrated Development Environment. (If you try to position a control over another, the one being positioned moves when you release the mouse.) However, controls can always be repositioned programmatically (with, say, (setf left) or (setf top)). This property does not affect programmatic repositioning. It only affects the design of forms.
