如何從java類的FXML文件中獲取按鈕位置

我使用javafx scene builder創建了接口的fxml文件。現在我需要獲取界面上的按鈕位置，但是當我調用按鈕方法來獲取X，Y座標時，返回的值爲0.0！謝謝先進。如何從java類的FXML文件中獲取按鈕位置

什麼時候你想獲得座標？展示你的舞臺之前還是之後？ – 2014-08-28 19:45:41

您好，感謝您的答覆。我用下面的代碼解決了它。

Button bt; 

Bounds localBounds = bt.localToScene(bt.getBoundsInLocal()); 

double popupX = bt.getScene().getWindow().getX() + localBounds.getMaxX(); 
double popupY = bt.getScene().getWindow().getY() + localBounds.getMaxY();

我希望代碼可以幫助別人。
