How to programatically increase number of pages of a tab control ?

[Imagineer]

Dear All,

Am trying to make a generic configurable GUI where the configuration data is in a CSV (or any) file and the LabVIEW shall read the contents and accordingly generate a GUI. In current scenario, the CSV may have data for a single or multiple pages, so programatically how do I add or delete pages of a Tab control.

Thanks and Regards,

Did you try a search? This question has been asked many times before. You cannot add pages at run-time. You can hide/show ones you don't use.

Yep I tried searching with above question, but did not get any results, not even close - Thats why posted this question.

Well, it appears you have your answer then.

Yep I got the search criteria.....and looking through it

Imagineer,

Even if I posted a VI that would add another tab page to a tab control, you would still need to put controls and indicator on the page.

If a "completely unspecified GUI appearence" is a requirement for your project then you should look into using the Picture Control. Although it may look a little complicated, it is a lot easier than LabVIEW Scripting* plus it is actually supprted.

*LabVIEW Scripting requires a specail license from NI but allows the programatic manipulation of VIs using VIs. Let me try to put it another way. I have delivered multiple applications that make use of the Picture Control to realize GUI that can not be layed-out at development time. I don't have the guts to even dare trying to deliver one that uses scripting.

Another possibility is to use a sub-panel. The sub-panel would, in essence, display a VI whose front panel was the contents of the tab page. You could use a dropdown or some other control to select what's displayed. Don't know if this will work for your architecture, though.

I have done what you are trying to do using subpanels. Through a combination of subpanels and VI server you can define an application framework that is reconfigurable at runtime by installing different plugins into the subpanel.

Dear All,

Thanks for the valuable inputs, but still unable to achieve my goal - Create a Tab panel on the fly and as well add/delete/rename pages on the runtime.

1] I tried using the Picture Tool but unable to figure out a way to add and rename pages to a tab control ?

2] Using subpanels, is it possible to add/delete pages and as well  rename the page, and also placing controls inside the tab pages ?

One approach: I can create multiple tab pages and make them invisible with each page having a blank picture to add controls dynamically. In the run-time depending on condition make required number of pages visible, but still am unable to edit the page name ?

Any help ?

Thanks and Regards,

You are having difficulty because you are still trying to use a tab control.  All of the suggestions given are based on not using a tab control at all. You cannot rename the tab pages at run-time. The tab control datatype is an enum, which cannot be edited at run-time.
