Outsourcing front panel controls to a floating SubVI front panel

It was a pleasure. Have a nice rest of the day.

Hello,

I'll writing here because my application is quite the same as described on this post.

I have a main VI controling the data acquisition, and there's an add button to insert Online Displays (Graphs, Numerical Indicators). Each one I have created using Queues on SubVI. The communication between the main VI and the SubVI's is ok.

What I am struggling is how to keep the SubVI Front Panel above the MainVI FrontPanel. I've already set the SubVI property to be FrontMost, and when I called it, FP shows up, but when I click back on the main vi form, the subVI FP goes backward.

How to maintain the SubVI frontmost????

Thanks

Personally, I'd look into using a subpanel.  Your other option would be to make your subVI Modal.  But this will prevent the user from doing anything on other VI windows.

I've tried SubVI modal, but I need to control the mainVI.

If using subpanel, I can use it as a window, where I can move, resize??? I need to keep this functions, because the idea is the user configure how his online screen will be during data acquisition.

If you still need to manipulate the main VI, then your floating window can't always be on top.  So that requirement doesn't make sense to me.

The subpanel doesn't allow for resizing.  But it basically imbeds your subVI's panel into your main VI's panel.
