删除默认工具栏中这些按钮

AR版本15；目前已经用viewer.toolbar.desktop.removeItem("$zoom");删除了放大的按钮；请问这些默认按钮是否也能删除？如果可以，分别对应的ID是什么？

您好，可以参看下面的:

viewer.toolbar.desktop.layout(layout)
这个里面都对应的每个选项按钮


目前分别有以下这些:
"$navigation", "$split", "$refresh", "$split", "$history", "$split", "$mousemode", "$zoom", "$fullscreen", "$split", "$print", "$singlepagemode", "$continuousmode", "$galleymode"
