Improvements to Selecting a List Item

In LabVIEW 2020 , you can change the value of a list item in a ring control, enum, or I/O control or constant by using the Select Item dialog box. Right-click the control or constant on the front panel or constant on the block diagram and select Select Item. This dialog box replaces the Select Item shortcut menu item.



Improvements to Moving between Subdiagrams

In LabVIEW 2020 , you can change the visible frame of a Case, Event, or Conditional Disable structure by using the Show Case dialog box. Right-click on the structure border and select Show Case. This dialog box replaces the Show Case shortcut menu item.



Improvements to Rearranging Cases or Subdiagrams

This new feature originated from a suggestion on the NI Idea Exchange discussion forums.

The Rearrange Cases dialog box has been redesigned and includes the following new functionalities:

  • Rearrange multiple cases
  • Delete one or more cases
  • Sort only selected cases within the case list

Improvements to Displaying Errors

LabVIEW 2020 changes the way a VI or library reports errors when the VI or library is error-free but has a broken dependency. In LabVIEW 2019 and earlier, the Error list window displays an error about the immediate dependency of the VI or library. Double-click the error to open the immediate dependency. In LabVIEW 2020 , the Error list window displays the error: ROOT CAUSE: Dependency is broken. Double-click the error to open the broken dependency that causes the error.

Launching the Cluster Size Dialog Box

This new feature originated from a suggestion on the NI Idea Exchange discussion forums. In addition to right-clicking, you can double-click the Array to Cluster function to open the Cluster Size dialog box.

Displaying the Last Item in a Ring Control

You can hide the last item in a ring control so that users cannot select the item while the VI runs. To show or hide the last item, right-click the ring control and select Show/Hide Last Item When Running. You can also use the Last Value Hidden property to show or hide the last item in a ring control programmatically.
