Scripting to change Diagram Properties

[isaacjoh]

Hi all, I'm trying to change the Diagram Property "Show Additional Parents" via JScript. The reason for this is that it's very tedious to go into each diagram and either check/uncheck this box. I'm trying to automate this and just run it for a package with numerous diagrams, looping through each and either checking/unchecking the box automatically.

I looked at the EaDiagram.WriteStyle and EaDiagram.ReadStyle options but I have found that they only work for the diagram property "Show Connector Property String" and "Show Element Property String". I assumed the WriteStyle function could be used for any of the diagram properties but that is not the case I guess. Any help would be much appreciated, thank you in advance!!

Thanks for the quick reply Qwerty! So you're saying if I add it to the StyleEx column, it'll work? Right now I see HideParents=1 or HideParents=0 in the PDATA column but StyleEx has a bunch of other stuff.

The question I have is whether you meant PDATA. If you did, there's no way to access PDATA in EaDiagram unfortunately. If you say it'll still work if I add HideParents=1 to the StyleEx, that'll be great because I can access StyleEx.

I was too fast with my reply (and you with reading). StyleEx does not seem to work, but modifying PDATA with HideParents=1;

See also p. 46 of my Inside EA book.

I'm cross checking currently.

You can modify PDATA by using

Code: [Select]

Repository.Execute ("UPDATE t_diagram SET PATA='...' WHERE ...")
This is an undocumented/unsupported function but it works and is widely used to do things like this. Of course you don't get support from Sparx when using it.

So it seems I got it. There is an ExtendedStyle property for the diagram object which you can access from the API (this must have been introduced in a later EA version). You can check this to contain the HideParents attribute and change the assignment or add it if it's not present.

Perfect!! That's exactly what I need. It should be a simple change from here. Thank you so much, I really appreciate it!!
