ActivityPartition vertical in diagram - java api

[Jeff Hyams]

I am using the java api to create a diagram.  I have an ActivityPartition and when I add it as a DiagramObject is shows up horizontal.  I would like to be able to automatically have it be vertical instead.  I can obviously change it through the UI, but I have not been able to figure out how to get the system to make it vertical through the java api.

Here is the psuedo code:

partitionElement = element.GetElements().AddNew("partition", "ActivityPartition");
diagram.GetDiagramObjects().AddNew(partitionElement.GetName(), "");

update/refresh/etc...

Is there an attribute or call I can make to have the system tell it to draw vertically instead of horizontally?

Thanks,

You need to set

Code: [Select]

diagramobject.style="VPartition=1"(without having verified that since t_diagramobjects.ObjectStyle triggers it this way).

Thanks for the quick reply! This was exactly what I needed and it worked perfectly.

For reference, this is the call in java:

diagramObject.SetStyle("VPartition=1");

Is there documentation of the full available style settings somewhere?  

Thanks,

The best you can get is probably my Inside book

diagramObject.SetStyle("VPartition=1");

Be careful with a call like that. You could overwrite existing style options.

Well, the EA help states:

Write only (reading this value gives undefined results)
The style information for this object.

So I guess that =1 wiil make it vertically and =0 will turn it back to horizontally. There's an additional link on setting the style in the help which talks about that semi-colon style. But it's a bit absurd that you can't read the existing style values (except through our beloved trap door SQLQuery).

The web documentation for the Diagram object style has this note :

Write only (reading this value gives undefined results)

Is there a different way to set a single style value without messing up the existing ones, then?  What I have now works for my current problem, but I can see needing to use this in other places in my code.

qwerty,

I am all for books if there is one available send me a link.

Just click the signature below my posts  

I'll see what happens with the style and post the results here.

So: if you set diagramObject.style="" EA clears all settings. Unlike what the help says diagramObject.style returns the current settings as a semicolon-separated list (Roy, can you cross check this?). So you can check this and append the new value or remove it before assigning style once again.

Having taken advice, I have updated this table entry to read:

Read/Write
The style information for this object. Returns a semi-colon delimited string that defines the current style settings. Changing a value will completely overwrite the previously existing value, so caution is advised to avoid losing existing style information that you want to keep.

You should probably test this in a sandbox model to make sure it gives you the results you want, before you use it in your development or production systems.
