如何调整gojs按钮的大小

Question

我在 gojs 中有一个使用组的图表。每个组都有一个 SubGraphExpanderButton。我想相对于图形其余部分（节点、链接等）的大小增加 SubGraphExpanderButton 的大小。我怎么做？我无法在此处的文档中找到它：https://gojs.net/latest/intro/buttons.html 下面是我的 GroupTemplate 代码：

// define the group template
myDiagram.groupTemplate =
  $(go.Group, "Auto",
    {
        isSubGraphExpanded: false,  // initially, make all groups collapsed 
        layout: $(go.LayeredDigraphLayout,
                  { direction: 0, columnSpacing: 10 }),
        memberAdded: function(grp, part) {
            grp.visible = true;
        },
        memberRemoved: function(grp, part) {
            if (grp.memberParts.count <= 0) grp.visible = false;
        }
    },
    $(go.Shape, "Rectangle", new go.Binding("stroke", "color"),
      { fill: COLOR_WHITE, stroke: COLOR_GRAY, strokeWidth: BORDER_STROKE_WIDTH }
    ),
    $(go.Panel, "Vertical",
      { defaultAlignment: go.Spot.Left, margin: 15 },
      $(go.Panel, "Horizontal",
        { defaultAlignment: go.Spot.Top },
        $("SubGraphExpanderButton", { width:8, height:20 }),
        $(go.TextBlock,
          { font: "Bold 40px Sans-Serif", margin: 4, stroke: COLOR_BLACK },
          new go.Binding("text", "key"))
      ),
      $(go.Placeholder,
        { padding: new go.Margin(0, 10) }
      )
    )
  );

} 谢谢！

而不是设置按钮的 width 和 height，你可以尝试设置它的 scale.
