禁用剩余按钮，单击一个按钮 [英] Disabling remaining Buttons, On Click of one button

问题描述

我在Swing应用程序中禁用/启用按钮时遇到小问题。这是一个非常基本的问题，但我是这个概念的新手。



我有一个要求，有2个按钮可以执行2个单独的操作。



1）最初跑步B1& B2应该是可见的/启用的。



2）如果B1点击，那么B2应该被禁用/不可见。完成B1工作后，B1和& B2应该是可见/已启用。



3）如果B2单击，则B1应被禁用/不可见。 B2工作完成后，B1& B2应该是可见的/启用的。



但是，我的问题是，处理完B1 / B2后SetEnable / SetVisible正在工作。



它应该在开始之前被禁用并在完成任务后启用



在这种情况下有人可以提供帮助吗？



以下是我的代码...

i have small problem while disabling/enabling buttons in Swing Application. It's very basic problem, but I'm new to this concept.

I have a requirement like, having 2 buttons to perform 2 individual operations.

1)While Running initially B1 & B2 Should be Visible/Enabled.

2)If B1 Clicked, then B2 should be disabled/Invisible. After B1 work Completed, then Both B1 & B2 Should be Visible/Enabled.

3)If B2 Clicked, then B1 should be disabled/Invisible. After B2 work Completed, then Both B1 & B2 Should be Visible/Enabled.

But, my problem, is, after processing B1/B2 SetEnable/SetVisible is working.

It should be disabled before start and enabled after completing task

Can anyone help in this case?

Below is my Code...

import java.awt.Font;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.WindowConstants;

public class FinCSV implements ActionListener {

JFrame frame = new JFrame("ICON");
JPanel panel = new JPanel(new GridLayout(2, 1, 4, 4));
JButton primaryButton = new JButton(" Primary Process");
JButton secondaryButton = new JButton(" Secondary Process");

public static void main(String[] args)
        throws Exception {
    FinCSV msql = new FinCSV();
    msql.initGUI();
}

public void initGUI() {
    this.primaryButton.setActionCommand("Primary");
    this.secondaryButton.setActionCommand("Secondary");
    this.primaryButton.addActionListener(this);
    this.secondaryButton.addActionListener(this);

    this.primaryButton.setFont(new Font("Serif", Font.BOLD, 22));
    this.secondaryButton.setFont(new Font("Serif", Font.BOLD, 22));

    panel.add(this.primaryButton);
    panel.add(this.secondaryButton);
    frame.setContentPane(panel);
    frame.setSize(650, 300);
    frame.setVisible(true);
    frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}

public void actionPerformed(ActionEvent e) {

    if (e.getActionCommand().equals("Primary")) {
         secondaryButton.setVisible(false);
   // secondaryButton.setEnabled(false);
        for (int i = 0; i < 10000; i++) {
            System.out.println("[ " + (i + 1) + " ] Inside Primary Process");
        }
          secondaryButton.setVisible(true);
   // secondaryButton.setEnabled(true);
    } else if (e.getActionCommand().equals("Secondary")) {
        primaryButton.setVisible(false);
   // primaryButton.setEnabled(false);
        for (int i = 0; i < 10000; i++) {
            System.out.println("[ " + (i + 1) + " ] Inside Secondary Process");
        }
        primaryButton.setVisible(true);
   // primaryButton.setEnabled(true);
    }
}
}

推荐答案

我更新了标记。



您正在使用：

I updated the markup.

You are using:

primaryButton.setVisible(true);

使按钮工作/不工作。这不是一个好习惯，因为用户会错过控件 - 并且UI中的动态更改可能会轻易搞砸所有内容。



请使用

to make the buttons working/not working. That is not good practice, cause the user is going to miss the controlls - and the dynamic change in your UI will probably easily mess up everything.

Please use

primaryButton.setEnable(true); // enable
primaryButton.setEnable(false); // disable

哪个应该更好。

你可能需要在改变按钮状态后重绘你的UI。

that should work better.
YOu might have to redraw your UI after changing the state of the buttons.
