Question

我需要帮助在LINUX环境中的现有应用程序中生成击键。我完全清楚Dev C ++中有些库可以完全满足我的需求，但在Windows中我需要在Linux中使用类似的东西。我google了很多，但无法找到任何解决方案。下面是Dev C ++库的代码，我想在Linux中使用类似的东西。任何帮助，建议和批评都是最受欢迎的。

void GenerateKey(int vk , BOOL bExtended)  
{  
  KEYBDINPUT kb = {0};  
  INPUT Input = {0};  

  // generate down   
  if(bExtended)  
    kb.dwFlags = KEYEVENTF_EXTENDEDKEY;  
  kb.wVk = vk;     

  Input.type = INPUT_KEYBOARD;  
  Input.ki = kb;  
  ::SendInput(1, &Input, sizeof(Input));  
  // generate up    
  ::ZeroMemory(&kb, sizeof(KEYBDINPUT));  
  ::ZeroMemory(&Input, sizeof(INPUT));  

  kb.dwFlags = KEYEVENTF_KEYUP;  
  if(bExtended)   
    kb.dwFlags |= KEYEVENTF_EXTENDEDKEY;  

  kb.wVk = vk;  
  Input.type = INPUT_KEYBOARD;  
  Input.ki = kb;  
  ::SendInput(1, &Input, sizeof(Input));  
}

谢谢和问候， SamPrat

您想要的是创建和初始化XKeyEvent结构并使用XSendEvent发送它。

务必检查man xkeyevent和man xsendevent

来自man xkeyevent：

   typedef struct {
        int type;                /* KeyPress or KeyRelease */
        unsigned long serial;    /* # of last request processed by server */
        Bool send_event;         /* true if this came from a SendEvent request */
        Display *display;        /* Display the event was read from */
        Window window;           /* ``event'' window it is reported relative to */
        Window root;             /* root window that the event occurred on */
        Window subwindow;        /* child window */
        Time time;               /* milliseconds */
        int x, y;                /* pointer x, y coordinates in event window */
        int x_root, y_root;      /* coordinates relative to root */
        unsigned int state;      /* key or button mask */
        unsigned int keycode;    /* detail */
        Bool same_screen;        /* same screen flag */
   } XKeyEvent;

要获取关键密码，请检查/usr/include/X11/keysymdef.h，然后使用xev

我找到了brief introduction。
