Question

我一直在将我为c＃所做的项目转换为java，而我在实现最后一部分时遇到了麻烦。该项目是一个梦幻般的足球跟踪器，问题在于让用户进入并更改活跃的名单和主要名单。

到目前为止，对其中任何一个进行更改都没有问题，或者问题是我想要组合功能，以便当他们完成一个名单时，他们可以根据需要对其他名单进行更改。

奇怪的是，我让它以一种方式工作，以便用户可以更改那里的活动名单，然后切换到那里没有问题的主名单;但是它不起作用的另一种方式用户可以更改主名单。

当他们说他们想要更改其他名单时，setVisible不会对包含用户主名单的JList起作用。

//This is the method that sets up the users active roster
public void activeRosterLook()
{
   //scroll holds the users master roster
  // this is the issue it will work in one instance but not the other
  // so when this method is called the first time it works
  // but when it is called a second time or called after 
  //the user changes the master roster
 // it decides not to become invisible
scroll.setVisible(false);

//bar holds the users active roster 
bar.setVisible(true);

// master is a button that when clicked starts the master roster change
master.setVisible(false);

//actuve is a button that when clicked starts the active roster change
active.setVisible(false);

// prompt is a label that gives directions on the frame 
prompt.setVisible(false); 

}

// this if checks to see that the Done button which triggers this change is clicked
if(Done.equals(e.getSource()))
{
    // this if makes sure the master button was clicked 
    if(ismaster)
    {
       // changing the booleans up so that my frame runs properly 
       isactive = true;
       ismaster = false;

       // this if makes sure that the active roster is not empty
       // I have this here because when they go change the active roster it
      // fills both rosters and when they go change the master it only fills the master              
      // roster 
       if(activePlayers[0] == null)
       {
           try
           {
             this method accesses the file that has the active roster data  
              loadActiveRoster();
           }
           catch(IOException ioe)
           {
              //This catch will never run the way I have the files set up
           }
       }
       // this method is called the issue is with the actual look method 
       activeRosterLook();
    }
    // this runs when active is clicked
   if(isactive)
  {
      // doing the same thing swapping the booleans 
      ismaster = true
      isactive = false

      // and this method will change the frame to the master roster changes
      // the only difference is that this method works and the changes occure
      masterRosterLook();
  }

}
else
{
   // this also works if the user does not want to change anything else sends
   // them back to the hub or the form that launches these frames
   StartUpForm hub = new StartUpForm(true);
    dispose();
}

 }

我想知道是否有人会想到为什么setVisible会在一个上工作 jList而不是其他？也就是为什么setVisible将在这个特定的名册中工作一种情况而不是另一种情况？

JList未被设置为隐藏工作之前
