卸载键盘快捷键 - UnregisterHotkey ​

函数简介 ​

卸载已注册的键盘快捷键监听。

接口名称 ​

UnregisterHotkey

DLL调用 ​

int UnregisterHotkey(long ola, int keycode, int modifiers);

参数说明 ​

参数名类型说明
ola长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
keycode整数型按键码。
modifiers整数型修饰键组合，使用位或组合，见下表。

modifiers 修饰键 ​

将需要的修饰键 按位或（|）相加 后传入 modifiers 参数（须与注册时一致）：

值说明
1左 Shift
2左 Ctrl
4左 Meta（Win 键）
8左 Alt
16右 Shift
32右 Ctrl
64右 Meta
128右 Alt

位运算组合示例 ​

csharp
// 卸载 Ctrl + Alt + F9（与注册时 modifiers 一致）
int modifiers = 2 | 8;  // 10
ola.UnregisterHotkey(0x78, modifiers);
cpp
// 卸载 Ctrl + Alt 组合键
int modifiers = 2 | 8;
ola.UnregisterHotkey(120, modifiers);
python
# 卸载 Ctrl + Alt + F9
modifiers = 2 | 8
ola.UnregisterHotkey(0x78, modifiers)
