JOptionPane.YES_OPTION ==每个按钮上的ENTER [英] JOptionPane.YES_OPTION == ENTER on each button

问题描述

我有一个这样的选项对话框:

I have a option dialog like this:

String[]  options = ["Yes", "No"]; //button names

int n = JOptionPane.showOptionDialog(singleFrameService.getFrame(),
        "Some Question?",
        "",
        JOptionPane.YES_NO_OPTION,
        JOptionPane.QUESTION_MESSAGE,
        null,     //do not use a custom Icon
        options,  //the titles of buttons
        options[0]); //default button title

//if press yes
if (n == JOptionPane.YES_OPTION){
    //make some if pressed Yes
}

当我使用鼠标并按是/否"-一切正常时... 但是，当我开始使用键盘时，请按TAB键转到否"按钮，然后按Enter-工作是"选项

When I used mouse and press Yes/No - all work fine... But when I start use keyboard, press TAB to go to "No" button, and then press ENTER - work "Yes" option

推荐答案

这一切都取决于外观，即AFAIK.在您的L& F中，"Enter"表示按默认按钮"(是).按下聚焦按钮可能是通过按下空格键来完成的.

It all depends on the look 'n feel, AFAIK. In your L&F, "Enter" means "press the default button" (which is Yes). Pressing the focused button is probably done by pressing the space bar.
