如何在CUBA平台中使用按钮打开Tabsheet的特定选项卡？

<window xmlns="http://schemas.haulmont.com/cuba/window.xsd"
        xmlns:ext="http://schemas.haulmont.com/cuba/window-ext.xsd"
        caption="My Window"
        class="com.company.myapp.web.screens.MyWindow"
        extends="/com/haulmont/cuba/gui/app/core/abstract-window.xml">
    <layout>
        <hbox id="topPanel" spacing="true">
            <button id="openTabButton" caption="Open Tab" invoke="onOpenTabButtonClick"/>
        </hbox>
    </layout>
</window>

public class MyWindow extends AbstractWindow {
    @Inject
    private Tabsheet tabsheet;

    public void onOpenTabButtonClick() {
        TabSheet.Tab tab = tabsheet.addTab("Tab Caption", null);
        tab.setCaption("New Tab");
        // 添加特定选项卡的内容
    }
}
