progammatically determine what pane a control is in

[TheQ]

I would like to pass a control reference to a subvi and have the subvi determine which pane the vi is in.  Is this possible?

As far as I know there's no direct way of doing this, but I'm only working in 8.2, so I don't know if the situation has changed in 8.6. You can, however, use property nodes to get the owning VI from the control reference, and then from that get the front panel object, and then from that get the panes[ ] array, and then for each pane get the list of controls, and then for each control you can see if the label matches your control's label. If so, you've got your pane.

If someone knows of a slicker way I'd love to hear it.

Thank you.  It sounds like I was on the right path, I just didn't think of the last step of comparing the list of controls on each pane to find the owning pane.  It might be a long process but it makes it programmatically possible.

If you mean by "which pane the vi is in" the subpanel the VI is in, then no.
Sadly, this is not possible. NI forgot to make two functions: one to get the
VI that is in a subpanel, the other to get the subpanel a VI is in... (At
least for version up to and including 8.5. Somebody please tell me this is
solved in 8.6...)

Regards,

Wiebe.

See the attached example: (LV 8.5)

Move the controls and indicators named in the enum between the two panes and run; it will return a reference to the pane the control is in...

The purpose of my asking was to find a easy way to determine the screen cordinates of a specific control.  I have succeeded with your help.  Here is the vi I created.  Please give feedback.  Thank you all again.

Hi Philip, 

Your GObj >> Obj Highlight method is throwing out error in my PC. When I click on that invoke node, it does not show that method at all.

What caould be the reason? Is it a private method?

You should note that both examples do not account for controls within containers (tabs or clusters). To do this, you can get the control's Owner property and climb up in a for loop until you reach a control who's owner is in the Panel class.

Another attempt is found here

It doesn't account for tabs or clusters.

But  here (in sourceforge) is a version that accounts for those obscure facts.
