GWTP嵌套的標籤主持人

Question

我想窩在GWTP標籤主持人。我有一幀（北）即卡組1和一個幀（西），該標籤組2.當我與組1相互作用我更新其控制組2.我已經看過嵌套標籤的例子中的嵌套的選項卡呈現主持人，但我一直無法確定我的錯誤。

兩個TabContainerPresenters是ManagmentTabsPresenter和SettingsTabsPresenter。這些孩子就像下面的HomePresenter。這些孩子的內容顯示在DockLayoutPanel的中心。我想讓ManagementTabsPresenter和SettingsTabsPresenter顯示在同一個DockLayoutPanel的West插槽中。

我看到的問題是，當運行此代碼時，ManagementTabsPresenter的revealInParent（）方法和SettingsTabsPresenter的revealInParent（）方法都會在我試圖在子選項卡上查看一個時調用。 （即homePresenter）。爲什麼這兩個revealInParent方法都被調用？我錯過了什麼？確實，SettingsTabsPresenter和ManagementTabsPresenter都位於顯示的父級選項卡中。這是否意味着當父tabcontainerpreseter是revelatedinparent這兩個tabcontainerprestners（nonleavetabcontentproxy）的revealInParent會叫什麼名字？

Answer 1

它應該是一個事件問題，當您選擇一個選項卡時，SelectionEvent可能會被錯誤的選項卡佔用。你能添加一些關於標籤初始化的代碼嗎？
