JTextField java?
JTextField java?
我的任务：
Create an application that displays a Hangman graphic for 10 steps. This graphic should be controllable via a text field and a slider (in the range 0-10) for test purposes. The text box updates the graph as soon as the value is changed and does not wait until the Enter key is pressed. If an invalid value is entered in the text field, then an error message is displayed instead of the graphic (with the method drawString text can also be "drawn"), if there should be no value there, then the graphic should remain empty.
在我的程序中，JSlider 上的图形更改工作正常，但通过文本字段输入没有导致更改，输入错误值时进行检查，我试过了，但没有任何结果显示。我不明白哪里出了问题，因为 JTextField 方法与 JSlider ...
相同
我已经把两个类的源代码放在下面了。
第一个Class:
进口，包裹...
public class HangmanFrame extends JFrame{
public HangmanFrame(){
super("Hangman");
HangmanPanel panel = new HangmanPanel();
JPanel mainPanel = new JPanel();
this.add(mainPanel);
mainPanel.setLayout(new BorderLayout());
JTextField t = new JTextField();
t.getDocument().addDocumentListener(new DocumentListener(){
@Override
public void changedUpdate(DocumentEvent arg0) {
try{
Integer.parseInt(t.getText());
}
catch(NumberFormatException ex){
System.out.println(ex.getMessage());
}
panel.repaint();
}
@Override
public void insertUpdate(DocumentEvent arg0) {
try{
Integer.parseInt(t.getText());
}
catch(NumberFormatException ex){
System.out.println(ex.getMessage());
}
panel.repaint();
}
@Override
public void removeUpdate(DocumentEvent arg0) {
try{
Integer.parseInt(t.getText());
}
catch(NumberFormatException ex){
System.out.println(ex.getMessage());
}
panel.repaint();
}
});
JSlider s = new JSlider(JSlider.HORIZONTAL, 0, 10, 0);
s.addChangeListener(new ChangeListener(){
@Override
public void stateChanged(ChangeEvent arg0) {
panel.repaint();
}
});
panel.setSlider(s);
panel.setTextField(t);
mainPanel.add(panel, BorderLayout.CENTER);
mainPanel.add(s, BorderLayout.PAGE_END);
mainPanel.add(t, BorderLayout.PAGE_START);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}
您的 JTextField 读取有效，但问题是您首先要检查滑块的值，因此如果滑块检查为真，则该方法会短路。为证明其正常工作，将滑块一直向右移动，然后在 JTextField 中输入 1 或 2。
如果这是我的项目并且我想测试这个效果，我会从绘画方法中获取所有逻辑，而是允许我的控制器更改观察到的 class 的状态值，调用 repaint()然后根据该状态绘制图像。
例如，像这样：
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Graphics2D;
