了JavaFx对话框除去底部空间

Question

考虑下面的代码：

public class Main extends Application { 
    public static void main(String[] args) throws Exception { 
     launch(args); 
    } 

    @Override 
    public void start(Stage stage) throws Exception { 
     final BorderPane p = new BorderPane(); 

     final Dialog dialog = new Dialog() { { 
      getDialogPane().setContent(new Button("TEXT")); 
     } }; 

     final Button bt = new Button("LAUNCH"); 
     bt.setOnAction(e -> dialog.show()); 

     p.setCenter(bt); 

     stage.setScene(new Scene(p)); 

     stage.show(); 
    } 
} 

结果是：

代码被简化例子。

问题在于底部有额外的空间。有什么办法可以删除它吗？谢谢。

你可以这样做：

@Override 
public void start(Stage stage) 
{ 
    final BorderPane p = new BorderPane(); 

    Stage dialog = new Stage(); 
    dialog.initModality(Modality.APPLICATION_MODAL); 
    dialog.setScene(new Scene(new Button("TEXT")));    

    final Button bt = new Button("LAUNCH"); 
    bt.setOnAction(e -> dialog.show()); 

    p.setCenter(bt); 

    stage.setScene(new Scene(p)); 

    stage.show(); 
}
