[news.eclipse.modeling.gmf] Re: Again, how to change diagram layout?

["Hao Zhang" <bjzhanghao@xxxxxxxx>]

Using ToolbarLayout I can implement swimlane on the canvas, the problem is 
swimlanes can not be reordered through drag and drop, do I need to manually 
implement these or GMF can generate such code?

Actually in GMF 2.0 now I can set "Layout Type" to "TOOLBAR_LAYOUT" Figure 
Viewmap in .gmfgen file, but how to allow nodes being dragged to change 
their sequence?
