Question

有没有办法为Text1和Text2文本定义自己的字体和颜色方案在setBorder方法中。 java新手，在SUN教程中找不到它。

我的代码

//Create Positions Table
 JPanel SpreadPanel = new JPanel();
 SpreadPanel.setBorder(BorderFactory.createTitledBorder(" Text 1    Text 2"));

此致西蒙

Answer 1

setBorder(BorderFactory.createTitledBorder(null, "text", TitledBorder.CENTER, TitledBorder.BOTTOM, new Font("times new roman",Font.PLAIN,12), Color.yellow));

第一个参数null或另一个边框（对于复合边框）您正在显示的第二个参数文本参数2的第3和第4个参数证明和文本的位置

第四个参数和第五个参数是设置字体和颜色的两个

Answer 2

如果您想要相同 {{1}中的每个字符串（例如Text1和Text2）的不同的字体和颜色您可能需要扩展AbstractBorder并覆盖TitledBorder。现有实现只有一种字体和一种颜色用于单个标题。

Answer 3

文字字体：

((javax.swing.border.TitledBorder) panel_1.getBorder()).setTitleFont(new Font("Tahoma", Font.PLAIN, 20));

文字颜色：

((javax.swing.border.TitledBorder)panel_1.getBorder()).setTitleColor(Color.WHITE);

Answer 4

如果您不熟悉Java和Swing，那么执行此操作的JavaDocs有点压倒性。 BorderFactory的JavaDocs位于：http://download.oracle.com/javase/1.5.0/docs/api/javax/swing/BorderFactory.html

以下是使用无衬线字体使文本变为红色的示例：

import javax.swing.*;
import javax.swing.border.TitledBorder;
import java.awt.*;
import java.io.IOException;

public class ScratchSpace {

    public static void main(String[] args) throws IOException {
        Font myFont = new Font("SansSerif", Font.PLAIN, 10);
        Color myColor = Color.RED;
        TitledBorder titledBorder = BorderFactory.createTitledBorder(null, " Text 1    Text 2", TitledBorder.DEFAULT_JUSTIFICATION, TitledBorder.DEFAULT_POSITION, myFont, myColor);
        JFrame frame = new JFrame();
        final JLabel label = new JLabel("Hello gruel world");
        label.setBorder(titledBorder);
        frame.getContentPane().add(label);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

}

Answer 5

我知道这是一个老问题。以为我想复活它，因为也许有人知道如何解决这个问题。我只有'部分解决方案'。

我很快就实现了你想做的边框。我重用了Java提供的内容，即在swing组件中解释HTML。

所有作品都很甜美，边框适用于普通文字或HTML文字，但您尝试使用不同字体大小的情况除外。

我不知道如何解决这个问题。但我对解决方案非常感兴趣。

我知道在计算textLengthInPixels变量时，程序将是用自己的字体大小来计算每个字符串的宽度。

问题是我不知道如何获取它，可能来自View，但不知道怎么做？

试试这个：

.setBorder(UIManager.getBorder("TextField.border"));

Java - 在setBorder中设置字体/颜色
