Swing：启用延迟按钮 [英] Swing: Enabling Buttons With Delay

问题描述

private void OptionsActionPerformed(java.awt.event.ActionEvent evt) 
{ 
 // After clicking on button X, I want 4 other buttons to show up
 // in a sequential order

ButtonTrue(); 
} 


public void ButtonTrue() 
{
    Audio_Options.setVisible(true);
    letsSleep();
    Control_Options.setVisible(true);
    letsSleep();
    Display_Options.setVisible(true);
    letsSleep();
    Network_Options.setVisible(true);
}

 public void letsSleep()
{
    try {
        Thread.sleep(10000);
    } catch (InterruptedException ex) {
        Logger.getLogger(MainMenu.class.getName()).log(Level.SEVERE, null, ex);
    }
}

我有4个按钮。我希望它们按顺序出现，例如：
Button1 - 10秒 - Button2 - 10秒 - Button3 - 10秒 - 按钮4

I have 4 buttons. I want them to appear in a sequential order such as : Button1 - 10seconds - Button2 - 10 seconds - Button3 - 10seconds - Button 4

问题：每当我调用函数ButtonTrue（），它们在等待30秒后一起出现。可能导致此问题的原因是什么？

Problem: Whenever I call the function "ButtonTrue()", they all appear together after waiting 30 seconds. What can cause this problem to occur?

推荐答案

• 不要使用 Thread.sleep（int） for Swing JComponent ，因为阻止了当前的EDT

  • don't use Thread.sleep(int) for Swing JComponent, because blocking current EDT
