Question

我有一个包含两个项目的SplitPane：进度条（顶部窗格）和操作按钮（例如，ok / cancel）作为底部窗格。加载页面时，将显示两个窗格。在初始加载期间，我希望隐藏顶部窗格并显示底部窗格。通过按钮单击发生操作事件时，将显示顶部窗格。我应该如何修改代码以便能够执行所描述的场景

设置splitPane分隔符的Controller类片段：

....
progressSplitPane.setDividerPosition(0, 0.0);
        progressSplitPane.setResizableWithParent(progressMainAnchorPane, true);

        actionButtonsWidget.getOkBtn().setOnAction(new EventHandler<ActionEvent>()  {
            @Override
            public void handle(ActionEvent evnt) {
                // Show progress bar and message console

                progressSplitPane.setDividerPosition(0, 0.75);
                pBarConsoleWidget.showProgressConsole();

                processCheckBoxSelections();
            }
        });
...
