如何在Java中从全屏模式转义? [英] how to escape from full screen mode in java?

问题描述

我已使用以下代码进入全屏显示:

I have used this code to go full screen:

private void fullScreenPerformed(java.awt.event.ActionEvent evt) {

    full = new JFrame();
    full.setSize(Toolkit.getDefaultToolkit().getScreenSize());
    full.setUndecorated(true);
    full.setVisible(true);
}

运行程序时，JFrame卡在全屏模式下，当按Escape键时无法将其关闭.因此，我必须重新启动或注销计算机才能再次回到正常屏幕.我希望用户能够通过按退出按钮"或使用其他组合来关闭它.我该怎么办?

When I run the program, the JFrame is stuck in the full-screen mode, and I can't close it when I press escape. Thus, I had to restart or log out of my computer to get back to normal screen again. I want the user to be able to close it by pressing the "escape button" or using other combinations. How can I do so?

推荐答案

您需要为此添加一个keyEventListener，如果您按了转义键，它将放置框架.之后，它将不再可用.

You need to add an keyEventListener for that, which disposes the frame if you have pressed escape. After that, it will not be usable again.

full.addKeyListener(new KeyAdapter() {
    public void keyPressed(KeyEvent evt) {
        if(evt.getKeyCode() == KeyEvent.VK_ESCAPE)
            full.dispose();
    }
});

请记住，框架需要聚焦，否则事件将不会触发.

Keep in mind that the frame needs to be focused, or else the event is not fired.
