tab control

[jilla]

Hello,

I am using a tab control in a data acquisition VI to display three different data sets on the front panel, depending on what the user wants to see. On the block diagram, I have the subVIs to collect each data set located in the approprate "case" of the tab control, along with the relevant indicators. I assume that the indicators for the non-selected tab cases are not updated until the case is selected, but will the data still be collected for the unselected cases? In other words I would like to always be collecting data from each data set (to write to an output file) but only want to display the data from the selected case. Thanks.

You don't need to do any "cases" on the block diagram for the tab state. Just use it as a purely cosmetic feature and do all the various code parts (data collection, etc.) in parallel. The data acquisition will not happen if it is inside a case that is not currently active.

Think of a tab control just as an easy way to display only a subselection of FP objects at any given time. The code does not need to know what the operator is currently looking at unless it is required for the code logic

I am sure that LabVIEW is smart enough not to constantly update hidden controls. Do you have performance issues?

Thanks altenbach,

No, I do not have any performance issues. I guess I just misunderstood the function of the tab control.

Some things are often just fine "no strings attached". 😄
