Display subvi of subvi in main vi subpanel

[phoenix-karthik]

In my application, I have to display hierarchical sub vis in main vi subpanel.(i.e I am displaying a subvi in subpanel, when I click a button on the subvi, it will call another subvi and that called subvi should open in subpanel of the main vi) How to do it?

You subVI needs to send a message to the main VI, telling it to change the VI in the subPanel.  The message content will need to include either the path to the VI or a reference to it.  I would use a queue to send the message, and for the data type of the queue, I would have a cluster containing a typedef'd enum (which specifies the message type), and a variant (containing message-specific data).

Another alternative is to have it insert itself into the subpanel. You need to pass a reference to the subpanel to the appropriate subvi. Remove the existing vi and insert the new one.

I believe there is an example of this in LV example finder.
