在Java Swing中,BevelBorder和SoftBevelBorder是两种常见的边框类型,它们能够为GUI元素提供立体感和视觉效果。本文将详细介绍这两个边框类型的使用方法和示例代码。
BevelBorder是Java Swing中的一个边框类型,它能够为GUI元素提供立体感和视觉效果。它有四种不同的类型:LOWERED、RAISED、LOWERED_INSET和RAISED_OUTSET。
要创建一个BevelBorder对象,需要使用下面的构造函数:
BevelBorder(int type, Color highlight, Color shadow);
其中type参数指定边框类型,highlight参数指定高亮颜色,shadow参数指定阴影颜色。
以下是一个使用BevelBorder的示例代码:
import javax.swing.*;
import java.awt.*;
public class BevelBorderExample extends JFrame {
public BevelBorderExample() {
JPanel panel = new JPanel(new GridLayout(2, 2));
panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
panel.add(createButton("Lowered", BorderFactory.createBevelBorder(BevelBorder.LOWERED)));
panel.add(createButton("Raised", BorderFactory.createBevelBorder(BevelBorder.RAISED)));
panel.add(createButton("Lowered Inset", BorderFactory.createBevelBorder(BevelBorder.LOWERED_INSET)));
panel.add(createButton("Raised Outset", BorderFactory.createBevelBorder(BevelBorder.RAISED_OUTSET)));
add(panel);
pack();
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
private JButton createButton(String text, Border border) {
JButton button = new JButton(text);
button.setFont(new Font("Dialog", Font.PLAIN, 20));
button.setBorder(border);
return button;
}
public static void main(String[] args) {
new BevelBorderExample();
}
}
上面的示例代码将创建一个包含四个按钮的JPanel,每个按钮使用不同类型的BevelBorder。效果如下图所示:
在上面的示例代码中,我们使用了BorderFactory的静态方法createBevelBorder()方法来创建BevelBorder对象。除此之外,我们还可以在创建JButton时为其指定BevelBorder,如下所示:
JButton button = new JButton("Raised");
button.setFont(new Font("Dialog", Font.PLAIN, 20));
button.setBorder(BorderFactory.createBevelBorder(BevelBorder.RAISED));
上面的示例代码演示了如何使用BevelBorder创建不同类型的边框。你可以复制以下代码并运行它,了解更多关于BevelBorder的用法:
import javax.swing.*;
import java.awt.*;
public class BevelBorderExample extends JFrame {
public BevelBorderExample() {
JPanel panel = new JPanel(new GridLayout(2, 2));
panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
panel.add(createButton("Lowered", BorderFactory.createBevelBorder(BevelBorder.LOWERED)));
panel.add(createButton("Raised", BorderFactory.createBevelBorder(BevelBorder.RAISED)));
panel.add(createButton("Lowered Inset", BorderFactory.createBevelBorder(BevelBorder.LOWERED_INSET)));
panel.add(createButton("Raised Outset", BorderFactory.createBevelBorder(BevelBorder.RAISED_OUTSET)));
add(panel);
pack();
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
private JButton createButton(String text, Border border) {
JButton button = new JButton(text);
button.setFont(new Font("Dialog", Font.PLAIN, 20));
button.setBorder(border);
return button;
}
public static void main(String[] args) {
new BevelBorderExample();
}
}
SoftBevelBorder是Java Swing中的另一个边框类型,它被设计为比BevelBorder更加柔和。它有四种不同的类型:LOWERED、RAISED、LOWERED_SOFT和RAISED_SOFT。
要创建一个SoftBevelBorder对象,需要使用下面的构造函数:
SoftBevelBorder(int type, Color highlight, Color shadow);
其中type参数指定边框类型,highlight参数指定高亮颜色,shadow参数指定阴影颜色。
以下是一个使用SoftBevelBorder的示例代码:
import javax.swing.*;
import java.awt.*;
public class SoftBevelBorderExample extends JFrame {
public SoftBevelBorderExample() {
JPanel panel = new JPanel(new GridLayout(2, 2));
panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
panel.add(createButton("Lowered", BorderFactory.createSoftBevelBorder(BevelBorder.LOWERED)));
panel.add(createButton("Raised", BorderFactory.createSoftBevelBorder(BevelBorder.RAISED)));
panel.add(createButton("Lowered Soft", BorderFactory.createSoftBevelBorder(SoftBevelBorder.LOWERED)));
panel.add(createButton("Raised Soft", BorderFactory.createSoftBevelBorder(SoftBevelBorder.RAISED)));
add(panel);
pack();
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
private JButton createButton(String text, Border border) {
JButton button = new JButton(text);
button.setFont(new Font("Dialog", Font.PLAIN, 20));
button.setBorder(border);
return button;
}
public static void main(String[] args) {
new SoftBevelBorderExample();
}
}
上面的示例代码将创建一个包含四个按钮的JPanel,和之前的示例代码一样,每个按钮使用不同类型的边框。效果如下图所示:
上面的示例代码演示了如何使用SoftBevelBorder创建不同类型的边框。你可以复制以下代码并运行它,了解更多关于SoftBevelBorder的用法:
import javax.swing.*;
import java.awt.*;
public class SoftBevelBorderExample extends JFrame {
public SoftBevelBorderExample() {
JPanel panel = new JPanel(new GridLayout(2, 2));
panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
panel.add(createButton("Lowered", BorderFactory.createSoftBevelBorder(BevelBorder.LOWERED)));
panel.add(createButton("Raised", BorderFactory.createSoftBevelBorder(BevelBorder.RAISED)));
panel.add(createButton("Lowered Soft", BorderFactory.createSoftBevelBorder(SoftBevelBorder.LOWERED)));
panel.add(createButton("Raised Soft", BorderFactory.createSoftBevelBorder(SoftBevelBorder.RAISED)));
add(panel);
pack();
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
private JButton createButton(String text, Border border) {
JButton button = new JButton(text);
button.setFont(new Font("Dialog", Font.PLAIN, 20));
button.setBorder(border);
return button;
}
public static void main(String[] args) {
new SoftBevelBorderExample();
}
}
本文介绍了Java Swing中的两种边框类型:BevelBorder和SoftBevelBorder。它们能够为GUI元素提供立体感和视觉效果,并且都有多种不同的类型可供选择。BevelBorder相对来说更为硬朗,SoftBevelBorder则更为柔和。在使用时,我们可以通过创建Border对象并将其应用于GUI元素来使用它们。
