JavaFX TextArea隐藏滚动条 [英] JavaFX TextArea Hiding Scroll Bars

问题描述

我有一个TextArea()，想隐藏垂直/​​水平滚动条.我看到该控件似乎具有一个内置的滚动窗格，可以根据需要显示.

I have a TextArea() and would like to hide the vertical/horizontal scroll bars. I see that the control seems to have a built in scroll-pane that shows as needed.

    TextArea numberPane = new TextArea();

    numberPane.setEditable(false);
    numberPane.setMaxWidth( 75 );

    // Set the characteristics of our line number pane
    numberPane.setId( "line-number-pane" );

在我的CSS文件中，我具有以下设置.

In my CSS file I have the follow settings.

    #line-number-pane
    {
        -fx-text-fill: white;
        -fx-background-color: black;
        -fx-font: 12px "Courier New";
        -fx-font-family: "Courier New";
        -fx-font-weight: bold;
    }

    #line-number-pane .scroll-pane
    {
        -fx-hbar-policy : never;
        -fx-vbar-policy : never;
    }

与预期的一样，文本区域的字体/颜色/大小也可以正常工作.但是，滚动窗格策略似乎无效.

As expected the text area font/color/size works just fine. However, the scroll-pane policy doesn't seem to work.

我应该能够通过CSS文件隐藏滚动条，还是有一些代码可以解决这个问题.

Should I be able to hide the scroll bars via the CSS file or is there some code that will do the trick.

谢谢.
