Copy/Paste Layout using GOJS Libaray

GoJS
1

Hello ,

We are using the Liecensed version for GOJS s/w.
Need an help on copying and Pasting the Layout/Digram in my code.
I tried the sample examples given on :
GoJS Commands -- Northwoods Software
Even tried to recall the the copy paste events using the handlers…SelectionCopied,ClipboardPasted…
But I am unable to copy the images/digrams ther.
Can anybody help us with the sample code for copy pasting Layout.

Thanks for all your help.Need your kind assistance asap.

I assume you are trying to copy nodes and links in code, not interactively – is that right? Can the user successfully select and copy and paste using the standard keys?

Did you want the user to select which parts to copy? If so, then you just need to call the CommandHandler methods copySelection and pasteSelection.

Or did you want to choose the parts programmatically? There are lots of ways of doing that. Add them to a List or a Set and then call Diagram.copyParts, all within a transaction.

Thanku so much for the update I am using the copySelection & pasteSelection commandhandler.
Can you please share good sample examples or any Link , so that idea to code using List or a Set will be more clear.

  1. Yes, think of the keys in the Model as being temporary keys, which you can replace in the future by calling Model.setKeyForNodeData, Model | GoJS API.
    Remember also that you probably want to update only in a Model Changed listener when ChangedEvent.isTransactionFinished is true. Please read GoJS Changed Events -- Northwoods Software for more information about transactions.

  2. Those collections are available on the DiagramEvent. See the documentation for more details: DiagramEvent | GoJS API.
