Identifying selected tabs within tab control

Question

I'm looking for a way to determine which tab is selected within the CVI tab control. The index is available, but the index isn't that helpful if the tabs aren't always in the same order. The Constant Name is used to identify controls on the tab page, but it doesn't look like there is a function to find the actual tab ID.
I was thinking that a work-around is to programmatically add the panels to the tab control and track the IDs against the index in a table.
The header file that is generated from the UIR only refers to the Constant Name as part of the #define associated with the controls.
Any ideas ?

Answer 1

It's true that you can use the label text and discover the active panel by means of a series of comparisons between strings, but it seems to me not the best way to go and surely not the fastest. The same consideration applies to ATTR_CONSTANT_NAME (the panel attributes which returns the text of the constant name, e.g. "MyPanel"). Moreover, this last solution leads to these additional critical points
1. If you load a panel more than once, this approach doesn't give you a unique solution
2. On the other side, supposing you can retrieve the value associated to the constant name, this value is unique only if all tab panel are defined in the same UIR file, otherwise their IDs could overlap
In my opinion your solution of programmatically load panels and save panel handles in a array is the only possible way to go, since only panel handles are unique throughout the whole application.
BTW, in the header file associated with the UIR panel constant names are listed too: in every group of #defines that refer to a panel and its controls, the very first is the panel constant name with its associated value (used in LoadPanel).

Proud to use LW/CVI from 3.1 on.
