Defer Panel Updates Property
Short Name: DeferPanUpdts
Installed With: Base Package
Class: Panel Properties
When you set this property to TRUE, LabVIEW redraws any front panel objects with pending changes then defers all new requests for front panel updates. For example, controls and indicators do not redraw when their properties or values change. If the operating system requests a redraw, such as if the window is no longer behind another window, LabVIEW redraws the front panel with the current properties instead of the original properties. If FALSE, LabVIEW immediately redraws the changed elements of the front panel.
Setting this property to TRUE can improve the execution speed and memory usage of a VI.
 | Note This property remains on after the VI finishes. Set this property to turn off before the VI finishes or the front panel cannot update with edits. Do not abort VIs that rely on this property to turn it off. |
