Determining if any popup panels are active

[MJF]

I have looked through the user interface library and have not found anything obvious... Is there any way to determine if a popup panel is active?

I have a situation where I may get an abort message from an external souce that would shut down the test sequence in progress. When this message arrives, I would like to close any active popups and display the abort status.

Just doing a RemovePopup(1) call gives an error, I only want to call it if there is an active popup.

I could do something like this:

   SetBreakOnLibraryErrors (0);
   RemovePopup (1);
   SetBreakOnLibraryErrors (1);

But I really prefer to avoid such shnanigans.

Hi, MJF.

There are a couple of ways to do this. You could use GetActivePanel() to find out which panel is active, or you could use GetPanelAttribute() with the attribute ATTR_ACTIVE.

Heres the definition from the CVI help:

ATTR_ACTIVE

Type:	Panel attribute
Description:	Indicates whether the panel or one of its child panels is the active panel. 0 = Panel not active 1 = Panel active
Restrictions:	Not settable.
Data Type:	integer

Let me know if you have any more questions. Have a nice evening.

Ah well, I was afraid somebody was going to say something like that. I was hoping for something very simple like a single function call that returns a 1 if there are active popups and 0 if not.

I'd see this as a nice feature to have in future, could we get it as a feature request for a future release?

Hi Martin,

I recommend submitting Product Suggeston for this feature.  This is a great way to let R&D know what features would make a big difference for you.
