如何在Java Swing中禁用键盘热键 [英] how to disable keyboard hotkey in java swing

问题描述

我想在我的netbeans项目中禁用诸如alt ctrl alt + f4 ctrl + alt + dlt之类的键盘热键，以便在我的应用程序处于打开状态时没有人可以打开任何东西

i want to disable keyboard hotkey such as alt ctrl alt + f4 ctrl + alt + dlt in my netbeans project so that no one can open anything while my application is on

推荐答案

好吧，禁用密钥是一件困难的事情，但是我认为可以用另一种方法解决您的问题:

Well, disabling keys is a difficult thing, but i think you problem can be resolved another way:

yourFrameOrWindow.setAlwaysOnTop(true);

这将使您的应用程序始终显示在屏幕上，如果全屏显示，则可以解决您的问题，但这不会禁用ctrl + alt + del或其他尝试关闭应用程序的尝试.

This will make your application always on the screen, if its full screen, then your problem is solved, but this will not disable ctrl+alt+del, or other attempts to close your application.

对于某些组合键，我认为您可以在onKeyPress方法中将它们映射，然后将其清空，如下所示:

And for some combinations of keys, I think you can map them in a method onKeyPress an then let it empty, like this:

void onKeyPress(int keyCode){
    if(keyCode == 43){
        //do nothing
    }
}

但是我认为有一个特定的按键组合监听器.

but i think have a specific listener for combinations of keys.
