Show children windows

Tonghua — Wed, 30 Oct 2013 00:22:34 GMT

Hi,

We are the team that doing NI supported spirometer.

1. Is there any example on show children windows?

structure:, startup VI contains 3 button for user to choose which child VI to open, and hide itself if child VI shows up( or show up if child VI closed).

StartUp VI

Education VI

Diagnostic VI

Incentive VI

2. After myDAQ gets data(real time plotting), is it possible to start analysis data (show slide bar) in same VI?

Trying to use a slide bar with two ticks to select partial of plot.

Could anyone give an example?

Thanks

Tonghua

On the sub-vi, set Show when called, and use Invoke nodes on the main vi to minimize/reopen that window.

What does that have to do with the original question or the reply?

I see, Thanks

Now the problem is how to bring main VI back when sub VI is closed.

Have the parent pass its reference (Class Vi Server Vi Vi) to the child.

Use a P-Node in the Child to write property Frontpanel Windows.Behavior as it opens and closes.

This example could open SubVI and return, but once click open again, it freeze. how to solve this?

You are correct. There a a few problems with that example.

Here it is cleaned up a little. Ask if there are things that do not make sense.

Hi, Jeff

I downloaded your attachment, but it seems the same as original one, which freeze after try to reopen subVI.

Tell me I am wrong.

D'Oh Try this instead.

Jordan - could you possibly replace the attachment in my previous post with the correct attachment in this one? If we can't, the link from the community site will just confuse the bejeebbers out of everyone. My idiocy shouldn't ruin everyones day- just yours and mine

Must be a Friday URGH! Can't I even spell? I must be chanelling Ben

Although Jeffs idea works, i'd say it's easier to have the main vi reset itself after the sub-vi call, it's easily done if you control program flow through error wires.

/Y

Leaving it up to the "Plug-in" lets different plug-ins do different things to the caller. Since its all done through VI Server either way, I suggested this manner that lets any "GUI" call the heavy lifter. Either approach is workable. The choice of implementation belongs, quite rightly, with the developer since only they know the system requirements.

Well, HOPEFULLY, they have a pretty good idea of what they need to do. That's not always the case though
