New Override Dialog Box

Requires: Base Development System

From the Project Explorer window, right-click a LabVIEW class or interface and select New»VI for Override from the shortcut menu to display this dialog box. Use the New Override dialog box to select an ancestor dynamic dispatch member VI to override. A dynamic dispatch member VI can override, or extend, the functionality of an ancestor dynamic dispatch member VI. LabVIEW dims the New»VI for Override option if the class or interface you select does not inherit member VIs that are available for you to override. The VIs in the ancestor class must be dynamic dispatch member VIs in order for you to override them.

This dialog box includes the following components:

• Select a Method To Override—Displays ancestor methods available to override.

  Note  A member VI can override a member VI from a parent class or interface only if the following settings are the same for both VIs: reentrant settings preferred execution settings priority settings access scope

LabVIEW uses the ancestor VI icon and overlays the icon mask of the child class or interface to create the icon of the new VI.
