Linux環境下模擬滑鼠操作
2020-06-16 17:40:28
在Linux/input.h中定義了以下結構體型別，用於標準按鍵的編碼操作：
Struct input_evnet{
Struct timeval time; //按鍵時間
_u16 type;//型別
_u16 code;//模擬成什麼按鍵碼
_u32 value;//按下還是釋放
}
EV_KEY:表示鍵盤；EV_REL表示相對坐標；EV_ABS表示絕對坐標
若事件型別為EV_KEY,code為按鍵的鍵值碼，vaule為0表示釋放，value為1表示按下；若事件型別為EV_REL,code為REL_X(表示滑鼠的X軸方向)或者REL_Y(表示滑鼠的Y軸方向)。
