Set scrollbar thickness
提问by Sinaesthetic
Is there a way to adjust the thickness of the scrollbar within a JScrollPane? the default is kind of clunky.
有没有办法在 a 内调整滚动条的粗细JScrollPane？默认设置有点笨重。

A quick but also dirty solution is to set the width/height explicitely to e.g. 10 pixels via
一个快速但又脏的解决方案是通过明确地将宽度/高度设置为例如 10 像素
jScrollPane.getVerticalScrollBar().setPreferredSize(new Dimension(10, 0));
jScrollPane.getHorizontalScrollBar().setPreferredSize(new Dimension(0, 10));
Other way would be to provide a proper ScrollBarUI.
另一种方法是提供适当的ScrollBarUI.

The following applies to the default LNF (Metal).
以下适用于默认的 LNF（金属）。
If you just want to set a specific size, then you can put this code before you create the JScrollPane (replace 40 with whatever size you prefer)...
如果您只想设置特定大小，则可以在创建 JScrollPane 之前放置此代码（将 40 替换为您喜欢的任何大小）...
UIManager.put("ScrollBar.width", 40);
If you want to scale the scrollbar based on the default size then something like this (before you create the JScrollPane)...
如果你想根据默认大小缩放滚动条，那么像这样（在你创建 JScrollPane 之前）......
UIManager.put("ScrollBar.width", (int) ((int) UIManager.get("ScrollBar.width") * 2.5));
If you want to change it aftercreating the JScrollPane things are a bit more complex, but not too bad...
如果您想在创建 JScrollPane后更改它，事情会更复杂一些，但还不错......
int scrollbarSize = <some dynamic value>;
UIManager.put("ScrollBar.width", scrollbarSize);
scrollPane.setVerticalScrollBar(scrollPane.createVerticalScrollBar());
scrollPane.setHorizontalScrollBar(scrollPane.createHorizontalScrollBar());
I hope that helps someone.
我希望这可以帮助某人。

int verticalScrollBarWidthCoefficient = 3;
scrollPane.getVerticalScrollBar().setPreferredSize(new Dimension(
(int) scrollPane.getVerticalScrollBar().getPreferredSize()
.getWidth() * verticalScrollBarWidthCoefficient,
(int) scrollPane.getVerticalScrollBar().getPreferredSize().getHeight()
));

simplest way for me was to edit the jquery.jscrollpane.cssfile directly. changing the width of .jspVerticalBar. :)
对我来说最简单的方法是jquery.jscrollpane.css直接编辑文件。改变 的宽度.jspVerticalBar。:)
