Summary, Tips, and Tricks on Customizing VIs

Module by: National Instruments

Summary: A summary and a few tips and tricks on customizing VIs.

  • Select File>>VI Properties to configure the appearance and behavior of a VI. You also can right-click the VI icon on the front panel or block diagram and select VI Properties from the shortcut menu.
  • If you want a single instance of the subVI to open its front panel when called, right-click the subVI and select SubVI Node Setup from the shortcut menu. Place checkmarks in the Show Front Panel when called and Close afterwards if originally closed checkboxes.
  • If you want every instance of the subVI to open its front panel when called, select File>>VI Properties and select Window Appearance from the Category pull-down menu. Click the Customize button and place checkmarks in the Show Front Panel When Called and Close Afterwards if Originally Closed checkboxes.
  • Assign keyboard shortcuts to controls by right-clicking the control and selecting Advanced>>Key Navigation from the shortcut menu.
  • Before you change VI properties, save a backup of the VI to a new location by selecting File>>Save with Options to avoid making the VI difficult to edit.
  • To edit a VI with properties that make the VI difficult to edit:
    • Break one of its subVIs. The VI opens in edit mode because it cannot run with a broken subVI.
    • If the VI has no subVIs, place it on the block diagram of a new VI.
  • The simplest method for adding VIs and controls to the Controls and Functions palettes is to save them in the user.lib directory.
  • To create or edit a custom palette view, select Tools>>Advanced>>Edit Palette Views.
  • Change to an icon- or text-only palette view by selecting from the Format pull-down menu.
