Mads Posted May 18, 2022 Report Share Posted May 18, 2022 (edited) Basic problem: If an element of a given cluster is changed - that value, and that value change alone, should be applied to several other clusters (which will otherwise retain their other element values). Known solutions: In the attached file (LabVIEW 2020 code) I have two ways of doing this: 1) using dynamic events and Set Cluster Elements by Name (OpenG), or 2) by using the Cluster To Array of VData.vi (also from OpenG). (Note: The use of array locals in the examples are there just to simplify the demo). Question: Are there other / better ways of doing it? A bit more background: In configuration windows I sometimes allow users various ways to choose to apply any *changes* globally or to a selection of targets. If e.g. they want to change the baud rate of 3 out of 5 different serial links they can choose the 3 links, and if they change anything in the communication setup of the first of them it will be applied to all 3 links (the rest of their setup will remain as before (they might still have different parity settings e.g.). I usually avoid clusters in the GUI so each change is handled individually, either in a dedicated value change event case (lots of coding needed...), or in a common case that uses the control reference to touch the correct element of the other target's configuration...(less code needed). However, in cases where the number of controls is very high, it can be nice to just have them in a cluster in the GUI as well - and to not have to write event cases to handle the change of each and every cluster element...
