How to link the two tabs of the plugin

When developing the plug-in, I encountered some problems. My plug-in has a tool window, and the tool window has two pages. I want to make a common toolbar for them, similar to the toolbar of maven. If I am on the first page After some operations are performed on the toolbar, it will have corresponding display effects. For example, after I click the icon, the icon will be grayed out, but it will only be grayed out on this page. I have no good way to make it on another page. Sync greyed out, hope to get help, thanks a lot。

开发插件的时候，遇到了一些问题，我这个插件有一个工具窗口，工具窗口有两个页面，我想为他们做一个公用工具栏，类似于maven那样的工具栏，假如我在第一个页面的工具栏进行了一些操作，他会有相应的显示效果，比如说我点击图标后，图标会变灰，但是它只会在此页面变灰， 我没有好的办法能让它在另外一个页面同步变灰，希望得到帮助，非常感谢
