[英]How do I get input from JTextField from other panels
I am new to using JTextFields and was curious on how to get input from 3 different panels.我是使用 JTextFields 的新手,并且对如何从 3 个不同的面板获取输入感到好奇。 The panels will take numbers from inputs and average the scores.
小组将从输入中获取数字并对分数进行平均。 For that, I want to access all 3 panels to do the math.
为此,我想访问所有 3 个面板来进行数学计算。 I have a panel for three different people's scores that I want to average.
我有一个面板,用于计算我想要平均的三个不同人的分数。 So I would like to get mattsTotalScore and add it with timsTotalScore and BensTotalScore and make the average appear after a button on a fourth panel.
因此,我想获取 mattsTotalScore 并将其与 timsTotalScore 和 BensTotalScore 相加,并使平均值出现在第四个面板上的按钮之后。
import javax.swing.*;
import java.awt.*;
public class MattPanel extends JPanel {
public MattPanel(){
Dimension size = getPreferredSize();
size.width = 250;
setPreferredSize(size);
setBorder(BorderFactory.createTitledBorder("Matt's Scores"));
JLabel memMatt = new JLabel("MEMORABILITY :");
JTextField textMemMattPane = new JTextField(10);
JLabel comMatt = new JLabel("COMPOSITION :");
JTextField textComMattPane = new JTextField(10);
JLabel mixMatt = new JLabel("MIX/MASTER :");
JTextField textMixMattPane = new JTextField(10);
JLabel soundMatt = new JLabel("SOUND DESIGN :");
JTextField textSoundMattPane = new JTextField(10);
JLabel enjoyMatt = new JLabel("ENJOYMENT :");
JTextField textEnjoyMattPane = new JTextField(10);
setLayout(new GridBagLayout());
GridBagConstraints gc = new GridBagConstraints();
///First Column ///////////////////////
gc.anchor = GridBagConstraints.LINE_END;
gc.weightx = 0.5; gc.weighty = 0.5;
gc.gridx = 0; gc.gridy = 0;
add(memMatt, gc);
gc.gridx = 0; gc.gridy = 1;
add(comMatt, gc);
gc.gridx = 0; gc.gridy = 2;
add(mixMatt, gc);
gc.gridx = 0; gc.gridy = 3;
add(soundMatt, gc);
gc.gridx = 0; gc.gridy = 4;
add(enjoyMatt, gc);
//Second Column //////////////////////
gc.anchor = GridBagConstraints.LINE_START;
gc.gridx = 1; gc.gridy = 0;
add(textMemMattPane,gc);
gc.gridx = 1; gc.gridy = 1;
add(textComMattPane,gc);
gc.gridx = 1; gc.gridy = 2;
add(textMixMattPane,gc);
gc.gridx = 1; gc.gridy = 3;
add(textSoundMattPane,gc);
gc.gridx = 1; gc.gridy = 4;
add(textEnjoyMattPane,gc);
}
}
You could try to use the getComponents()
method from JPanel to get all components, although you would have to somehow identify the TextFields like:您可以尝试使用 JPanel 中的
getComponents()
方法来获取所有组件,尽管您必须以某种方式识别 TextField,例如:
MattPanel panel = new MattPanel();
int sum = 0;
int nr = 0;
for(Component comp : panel.getComponents()){
if(comp instanceof JTextField){
String text = ((JTextField)comp).getText();
sum += Integer.parseInt(text);
nr ++;
}
}
double avg = sum/nr;
