PolylineConnection的孩子的ToolbarLayout？

Is there a way to specify a layout for children of a PolylineConnection?

有没有办法为PolylineConnection的子项指定布局？

I want to add several Labels to a PolylineConnection at ConnectionLocator.MIDDLE without the use of a container figure for the labels.

我想在ConnectionLocator.MIDDLE的PolylineConnection中添加几个标签，而不使用标签的容器图。

Both PolylineConnection and Label have EditParts, and the label's model objects are children of the polyline connection's model objects.

PolylineConnection和Label都有EditParts，标签的模型对象是折线连接的模型对象的子对象。

Ideally I want to add all label children of a polyline to ConnectionLocator.MIDDLE in a ToolbarLayout...

理想情况下，我想将折线的所有标签子项添加到ToolbarLayout中的ConnectionLocator.MIDDLE ...

What you are trying to do is mix two layouts: on the first hand you want to use a ConnectionLocator.MIDDLE to locate the figures, but on the other hand you want to have the figures at this location to have their own layout.

你要做的是混合两个布局：第一方面你想使用ConnectionLocator.MIDDLE来定位数字，但另一方面你想让这个位置的数字有自己的布局。

The only solution you have is to create a figure that uses a ToolbarLayout and locate it in the Polyline using the ConnectionLocator

您唯一的解决方案是创建一个使用ToolbarLayout的图形，并使用ConnectionLocator在Polyline中找到它

I've found a way to achieve what I wanted:

我找到了实现我想要的方法：

Very generally, the first child must be added at ConnectionLocator.MIDDLE, and the rest of the children relative to the child before them with the help of RelativeLocator like this (line would be in a loop over all figure children in connection's edit part):

通常情况下，必须在ConnectionLocator.MIDDLE中添加第一个子节点，并在RelativeLocator的帮助下将其余子节点相对于子节点添加到此处（行将在连接的编辑部分中的所有数字子节点上循环）：

figure.add(childFigure, 
           new RelativeLocator((IFigure) figureChildren.get(currentIndex - 1), 
                                   0.5, 
                                   1.7);

I've written a blog post with more details.
