在Java/Swing的全屏程序中停止使用Tab/Alt-F4

Question

在我的Java程序运行时,我需要一种方法来阻止人们使用其他程序.即停止人们切换标签并按Alt-F4.

Answer 1

使程序全屏使用;

 window.setExtendedState(Frame.MAXIMIZED_BOTH); //maximise window

 window.setUndecorated(true); //remove decorations e.g. x in top right

并使窗口始终在最顶层使用(阻止人们使用其他正在运行的程序);

window.setAlwaysOnTop(true);

Answer 2

您无法在Java级别执行此操作 - 您需要将操作系统置于某种"Kiosk模式"中.

未经请求的评论 - 您是否需要这个,因为您(或您的客户)讨厌您的用户,并希望他们永远诅咒您？您是否计划在程序中添加"关闭计算机"等功能？

Answer 3

如果您正在寻找全屏支持,这是我使用的代码.应该足以让你去.您只需要一个全局布尔变量来说明应用程序是否全屏.你可以修补它,让它显示你喜欢的.

    public void setFullscreen( boolean fullscreen )
    {
        //get a reference to the device.
        GraphicsDevice device  = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
        DisplayMode dispMode = device.getDisplayMode();
        //save the old display mode before changing it.
        dispModeOld = device.getDisplayMode();

        { //are we actually changing modes.
