我怎樣才能得到數據時，單擊TableView java FXML

我有一個表格下使用FXML JavaFX中的表格。您能否告訴我如何在下一次點擊表格時獲取並加載數據？我怎樣才能得到數據時，單擊TableView java FXML

這裏是我的控制器

有一個'User'類和一個'public void User（）'方法是一個不健康的組合。我建議遵循命名約定並用小寫字母開始方法名稱。 – fabian

另外，你能否澄清這個問題。你想要發生什麼，以及什麼用戶事件觸發它？我不明白「當我點擊下一張表格時如何獲取和加載數據」。 –

我的意思是，當我點擊用戶窗體上的表格時，表格上的數據自動加載到窗體上的textField上以編輯，保存或刪除 –

我想我知道什麼是問題。通常情況下，您可以在FXML中添加事件。如果你想點擊它，你必須與標籤onMouseClicked="" 其添加在這裏有一個例子：<TableView fx:id="pl2" onMouseClicked="#handleClickTableView" GridPane.rowIndex="1"> 爲了讓您可以添加類似這樣的東西你TableView中的價值：

@FXML 
private void handleClickTableView(MouseEvent click) { 
     UserList userlist = tableUser.getSelectionModel().getSelectedItem(); 
     if (userlist != null) { 
      usr.username = userlist.getUsername(); 
      dal.getUserId(usr); 
      txtUsername.setText(usr.username); 
      txtFullname.setText(usr.fullname); 
    } 
}

如果鼠標點擊表格視圖，它將完成你在方法中定義的內容。我希望這有幫助。乾杯
