我是JFrame,组件等的新手,但我正在尝试更改特定文本字段的大小,以便您可以实际看到您放入的内容。这是代码:
import java.awt.Dimension;
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
public class InterestCalculator extends JFrame{
private static final long serialVersionUID = 1L;
JLabel desc = new JLabel("This is a simple interest calculator.\n"
+ " Enter three fields to get the fourth.");
JLabel inteLabel = new JLabel("\nInterest: ");
JTextField inte = new JTextField();
public static void main(String [] args) {
InterestCalculator comp = new InterestCalculator();
comp.FrameHandler();
}
public void FrameHandler() {
setSize(500, 500);
setTitle("Template");
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
setLayout(new FlowLayout());
add(desc);
add(inteLabel);
add(inte);
inte.setSize(new Dimension(100,15));
validate();
}
}
这就是出现的结果:http://i.imgur.com/SoOEMNT.png 那么,我该如何解决这个问题?
答案 0 :(得分:4)
JTextField inte = new JTextField();
应设置多个列,I.E。:
JTextField inte = new JTextField(10);
另见Should I avoid the use of set(Preferred|Maximum|Minimum)Size methods in Java Swing?(是)。
同样适用于setSize(..)
。
