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，如 Ctrl+Alt 为 2+8=10。取值：左Shift(1)、左Ctrl(2)、左Meta(4)、左Alt(8)、右Shift(16)、右Ctrl(32)、右Meta(64)、右Alt(128)。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.StartHotkeyHook();
if (ret == 1) {
    ola.RegisterHotkey(120, 10, nullptr);
    ola.UnregisterHotkey(120, 10);
}
csharp
using OLAPlug;

var ola = new OLAPlugServer();
int ret = ola.StartHotkeyHook();
if (ret == 1)
{
    ola.RegisterHotkey(120, 10, (k, m) => 0);
    ola.UnregisterHotkey(120, 10);
}
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ret = ola.StartHotkeyHook()
if ret == 1:
    ola.RegisterHotkey(120, 10, lambda k, m: 0)
    ola.UnregisterHotkey(120, 10)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
int ret = ola.StartHotkeyHook();
if (ret == 1) {
    ola.UnregisterHotkey(120, 10);
}
cpp
var ola = com("OlaPlug.OlaSoft")
var ret = ola.StartHotkeyHook()
if(ret == 1) {
    ola.RegisterHotkey(120, 10, 0)
    ola.UnregisterHotkey(120, 10)
}
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.StartHotkeyHook()
If ret = 1 Then
    ola.RegisterHotkey(120, 10, 0)
    ola.UnregisterHotkey(120, 10)
End If

.局部变量 ola, OLAPlug
ola.创建 ()
ret ＝ ola.StartHotkeyHook ()
.如果真 (ret ＝ 1)
    ola.RegisterHotkey (120, 10, 0)
    ola.UnregisterHotkey (120, 10)
.如果真结束

import OLAPlugServer;

var ret = ola.StartHotkeyHook();
if(ret == 1){
    ola.RegisterHotkey(120, 10, function(k,m){return 0;});
    ola.UnregisterHotkey(120, 10);
}

变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
整数 ret = ola.StartHotkeyHook()
如果真 (ret ＝ 1)
{
    ola.RegisterHotkey(120, 10, 0)
    ola.UnregisterHotkey(120, 10)
}
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int32_t ret = ola.StartHotkeyHook();
if (ret == 1) {
    ola.UnregisterHotkey(120, 10);
}

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
StartHotkeyHook(instance);
RegisterHotkey(instance, 120, 10, 0);
UnregisterHotkey(instance, 120, 10);
csharp
using System.Runtime.InteropServices;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long CreateCOLAPlugInterFace();

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int UnregisterHotkey(long ola, int keycode, int modifiers);

long instance = CreateCOLAPlugInterFace();
StartHotkeyHook(instance);
RegisterHotkey(instance, 120, 10, 0);
UnregisterHotkey(instance, 120, 10);
python
from ctypes import CDLL, c_int, c_int64

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
StartHotkeyHook(instance);
RegisterHotkey(instance, 120, 10, 0);
UnregisterHotkey(instance, 120, 10);

返回值 ​

整数型。1 成功，0 失败。
