如何隐藏在JScrollBar的箭头按钮 [英] How to hide the arrow buttons in a JScrollBar

问题描述

我需要隐藏 <$的箭头按钮C $ C> java.awt.Scrollbar中（垂直）在AWT应用程序 。
有谁知道如何可以做到这一点？

I need to hide the arrow buttons of java.awt.Scrollbar(VERTICAL) in an AWT application. Does anyone know how this can be achieved?

我看到了一个例子<一个href=\"http://stackoverflow.com/questions/1786886/remove-arrows-from-swing-scrollbar-in-jscrollpane\">here,但code只是隐藏的按钮。为按钮保持静止的空置面积;它不是由滚动条所占据。

I saw an example here, but the code just hides the buttons. The vacant space for the buttons still remains; it is not occupied by the scroll bar.

要更确切地说，这里是我要达到什么样的屏幕截图。我不知道去了解它的方向。

To be more exact, here is the screenshot of what I should achieve. I am not sure which direction to go about it.

更新：我一直在寻找AWT的解决方案。但现在我愿意在Swing和建议。

Update : I was looking for a solution in AWT. But now I am open to suggestions in Swing as well.

推荐答案

试试这个..它取代了垂直滚动条的常规按钮与在尺寸为0x0的按钮。

Try this.. it replaces the regular buttons on the Vertical ScrollBar with buttons that are 0x0 in size.

这确实限制你的样子，虽然感觉：（

It does limit your look and feel though :(

JScrollPane scroller = new JScrollPane(mainPane);
scroller.setPreferredSize(new Dimension(200,200));
// ... etc
scroller.getVerticalScrollBar().setUI(new BasicScrollBarUI()
    {   
        @Override
        protected JButton createDecreaseButton(int orientation) {
            return createZeroButton();
        }

        @Override    
        protected JButton createIncreaseButton(int orientation) {
            return createZeroButton();
        }

        private JButton createZeroButton() {
            JButton jbutton = new JButton();
            jbutton.setPreferredSize(new Dimension(0, 0));
            jbutton.setMinimumSize(new Dimension(0, 0));
            jbutton.setMaximumSize(new Dimension(0, 0));
            return jbutton;
        }
    });

更新：对不起，这是一个摇摆的解决方案

Update: sorry, this is a swing solution
