问题描述
我正在使用此代码来确认用户单击JFrame的红色十字关闭按钮(右上角)时是否要退出
I'm using this code to confirm the user whether wants to quit or not when he CLICKS THE RED CROSS CLOSE BUTTON OF JFrame (right upper corner)
Object[] options = {"Quit, My Computing Fellow", "No, I want to Work more"};
int Answer = JOptionPane.showOptionDialog(null, "What would you like to do? ","Quit:Continue", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE,
null, options,options[1]);
if(Answer == JOptionPane.YES_OPTION){
System.exit(0);
}
else if (Answer == JOptionPane.CANCEL_OPTION) {
return;
}
但是问题是,如果用户单击CANCEL_OPTION,则框架完全关闭,但是我希望用户仍然打开框架,而不允许框架关闭.指导我,如果我正在做大事或其他事情?
but the problem is if the user clicks CANCEL_OPTION the Frame Closes at all, but i want the user to still open the Frame and not allow the Frame to close. Guide me If I'm doing the blunder or something else?
推荐答案
我有一个严重失误
Object[] options = {"Quit, My Computing Fellow", "No, I want to Work more"};
int Answer = JOptionPane.showOptionDialog(null, "What would you like to do?","Quit:Continue", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE,
null, options,options[1]);
if(Answer == JOptionPane.YES_OPTION){
System.exit(0);
}
else if (Answer == JOptionPane.CANCEL_OPTION) {
return;
}
很明显,我有两个选项,即YES_NO_OPTION,并且我打电话给CANCEL_OPTION真是个大错,所以else-if应该更改为:
It was clear that I have two Options i.e YES_NO_OPTION and I was calling the CANCEL_OPTION that was a real blunder so, the else-if should be changed to:
else if (Answer == JOptionPane.NO_OPTION) {
this.setDefaultCloseOperation(myclassreference.DO_NOTHING_ON_CLOSE);
}
在此之后;它的宾果游戏!我做完了!
after this; its bingo !!! I've done!
