Sv: Returning value from window

Wed Mar 22 07:45:13 UTC 2023

The logic could be that this line would set a reference to pListRef :
Set reference iList to pListRef.
A reference to the Field reference.

And this would set a reference to what pListRef references:
Set reference iList to pListRef.$ref.
A reference to the incoming list that is referenced by pListRef.

If that makes sense. Maybe.
So it is a chain of reference.
Incoming list -> Field reference -> Item reference.

So the .$ref would be:
Incoming list <- Field reference <- Item reference.

Without the .$ref the chain would only be:
Field reference <- Item reference.

Hi Daniel,

Sorry, not really. To be absolutely honest, if something does not work with references, I automatically try $ref at the end to see if it helps.

Regards

Rudolf

Yes Rudolf.
That made it.
Strange reference.
Can you explain what the difference is with and without the .$ref.

Thanks
Daniel

Hi Daniel,

You could try

Set reference iList to pListRef.$ref

Note the suffix $ref

Hi Rudolf

The iList is an Item reference.
I am bewildered that it does not reflect back to original list.
The Field reference does so I set the line on that just before closing the window.

Hi Daniel,

your iList variable needs to be of type ItemReference, and not List. Perhaps this is your problem in the code below.

Thanks Scotte

Clicking on a line in the presented list that is an item reference to the parameterlist pRef does not reflect back to the original list.
It works if I assign the line to the Field reference just before the select window is closed.

Set reference iList to pListRef.
Enter data.
Do pListRef.$line.$assign(iLine) ## With this line it works. Without the pListRef stays as it were.
Do $cwind.$close().
Quit method.

Passing things back and forth.
Yes, what you say is how I do it in Omnis7.
Thought there could be other ways in Studio.

Yes, that is how you set it up. Any change to the line should be reflected in the original variable. Look at the variable itself rather than how it displays on the original window. Perhaps a redraw it needed on the first window.

As for how to pass other things back and forth, you can pass a reference of the original window to the new window and the name of the method you want to be called. Then you know the name to call back to pass no back.

Do $windows.vClientSelect.$open(‘*’,kWindowNormal,iClientList,$cinst.$ref,’$passbackDataMethod’)

In new window:
Set reference iirOrigWindow to pfrPassedInRef Calculate icCallbackMethod as pcMethodName

Later in some other method:
Do iirOrigWindow.[icCallbackMethod](parameter1,parameter2)
