Capturing Keystrokes in GNU/Linux in C without X11

问题 If I am working in an application and I press key from keyboard, how can I capture that key (or string), including the source application's name, in C, under GNU/LINUX, in userland, without X11 :) Thanks. 回答1: Well, without X11 this problem is way more difficult. For the keystroke part you can use a code similar to this one, but you have to pass as an argument the device that you are reading (keyboard, usually /dev/input/event0 ) #include <linux/input.h> #include <sys/types.h> #include <sys

Is this possible? 回答1: It's possible but requires an implementation taking advantage of JNI which will not always be portable. Java System Hook is one such library that will work with Windows 32 & 64 bit. 回答2: I used something like that a while ago. Take a look at Java System Hook. It tracks global key presses (not just your Java application) via JNI. It worked fast

I want to create a console application that will display the key that is pressed on the console screen, I made this code so far: static void Main(string[] args) { // this is absolutely wrong, but I hope you get what I mean PreviewKeyDownEventArgs += new PreviewKeyDownEventArgs(keylogger); } private void keylogger(KeyEventArgs e) { Console.Write(e.KeyCode); } I want to know, what should I type in main so I can call that event? For console application you can do this, the do while loop runs untill you press x public class Program { public static void Main() { ConsoleKeyInfo keyinfo; do { keyinfo
