AutoLayout diagrams from API

[ContactIT]

Hi all,

I'm using the JAVA API to add all elements and links, that's OK !

Is it possible to do an Auto Layout to arrange diagrams ?

Thanks by advance !

Hard to find help and always with issue ...

Followinf the procided links, i found some informations but no way to make them working.

MegaObject mgObject = _mgObject;
MegaObject mgDiagram = mgObject.getCollection(diagramCollectionName);
MegaDrawing mgDrawing = mgDiagram.callFunction("drawing", "RW");

MegaAttribute o1 = mgDrawing .getAttribute(DiagramTypeObject.MA_DiagramTypeObjectArrangement);
System.err.println("o1 -> " + o1);
System.err.println("   -> value = " + o1.getValue());

Results with :

MEGA Error 0x80020009(GetProp) : PropGet(MetaAttribute DiagramTypeObject Arrangement <gxMbtR9L61C0>) is not valid for the Business Process MetaClass

Any help please ?

Thanks for the answer.

But i'm using ONLY the JAVA API.

I tried to use the "arrangeLayout" but some mistakes appears :

- The egdes between elements are "direct" and i don't know how to set them "ortogonal"

- The elements affected to participants (in lanes) doen't be into the lanes

- Impossible to configure the laes to be horizontal (using the default "participant_horizontal.mgs" shape)

Maybe the full auto positionning will help me, so maybe it as a possibility to remove the existing "Drawing" ???

Thanks by advance !

Hello 

For a diagram that does not have yet a text _drawing (that stores the graphical arrangement of diagram), an automatic arrangement will be triggered at first opening if the DiagramTypeParam is configured accordingly. No code is required, only configuration

See KB http://community.mega.com/t5/custom/page/page-id/mega-kb-solution?sid=50120000000mqOHAAY

There is also a function ArrangeLayout is available for the MegaDrawing object.  
See javadoc documentation

arrangeLayout(int layoutType, int lineStyle)
