Set Tunnel to default value by scripting


Recommended Posts

I have an issue when using this QDP :

- before using it, my VI has a broken arrow because a tunnel has some missing assignments

- after using it, the VI still has a broken arrow although my tunnel is set to use default if unwired

- if I click on the broken arrow, it turns into a non-broken arrow

What's the best way to force LabVIEW to re-assess the broken / non-broken state?

 

EDIT : also, as you close the I referenc too early (in the false case), the undo doesn't work.

Here's a versions with a few modifications :

- fixed the undo

- do nothing if launched from panel

- if selection is a case structure, take all tunnels and enable  "use default..." if not already enabled

- if zero tunnel were effectively modified, fail the undo

- if at least one tunnel was effectively modified, force recompile the VI to make sure LabVIEW will re-assess the broken arrow

Thanks Antoine

I have not enough test it before propose it. Sorry

I working on to correct bug when i receive your last message and modified version. Unfortunely, i can't test it because it's in LV2019 and I only have LV2018.

Is there possible to have it in LV2018 ?

Thanks

Thanks Antoine

I have tested your version, but it seems that it did not work if you have more levels of stacked case structures. I think it's because you don't use "Traverse for GObject.vi " like me.

My approach is to select tunnels before applying the change and not the case structure itself.

Here my new version with few corrections about your first remarks
