Set Border Thickness on JPanels?
提问by NiallMitch14
I'm wondering if it is possible to adjust the thickness of a border around a JPanel in Java? I currently have a border defined and the JPanel adds the border around it but I would like it to be a little thicker:
我想知道是否可以在 Java 中调整 JPanel 周围边框的粗细？我目前定义了一个边框，JPanel 在它周围添加了边框，但我希望它更厚一点：
Border border;
JPanel panel;
border = BorderFactory.creatLineBorder(Color.RED);
panel = new JPanel();
panel.setBorder(border);

I believe you could use BorderFactory
我相信你可以用 BorderFactory
panel.setBorder(BorderFactory.createStrokeBorder(new BasicStroke(5.0f)));

BorderFactory has a method that accepts two parameters - the Color and thickness
BorderFactory 有一个接受两个参数的方法 - 颜色和厚度
border = BorderFactory.creatLineBorder(Color.RED, thickness);
Alternatively, you can use the LineBorderclass to generate a thicker line border
或者，您可以使用LineBorder类生成更粗的线条边框
LineBorder border = new LineBorder(Color.RED, thickness)
panel.setBorder(border);

JPanel panel1=new JPanel();
panel1.setBounds(0,0,201,201);
panel1.setBorder(BorderFactory.createLineBorder(Color.BLUE,3));
Note:Here border thickness is 3 and color is blue.
注意：此处边框粗细为 3，颜色为蓝色。
