函数简介 ​

将屏幕坐标转换为窗口客户区坐标。

接口名称 ​

ScreenToClient

DLL调用 ​

int ScreenToClient(long ola, long hwnd, int* x, int* y);

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。
hwnd长整数型目标窗口的句柄。
x整数型指针传入屏幕X坐标，返回对应的客户区X坐标。
y整数型指针传入屏幕Y坐标，返回对应的客户区Y坐标。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.ScreenToClient(hwnd, "value", "value");
csharp
using OLAPlug;

var ola = new OLAPlugServer();
int ret = ola.ScreenToClient(hwnd, "value", "value");
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ret = ola.ScreenToClient(hwnd, "value", "value")
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
int ret = ola.ScreenToClient(hwnd, "value", "value");
cpp
var ola = com("OlaPlug.OlaSoft")
var ret = ola.ScreenToClient(hwnd, "value", "value")
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.ScreenToClient(hwnd, "value", "value")
text
.局部变量 ola, OLAPlug
ola.创建 ()
ret ＝ ola.ScreenToClient(hwnd, “value”, “value”)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var ret = ola.ScreenToClient(hwnd, "value", "value");
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
整数 ret = ola.ScreenToClient(hwnd, "value", "value")
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int32_t ret = ola.ScreenToClient(hwnd, "value", "value");

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
ScreenToClient(instance, hwnd, 100, 200);
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long CreateCOLAPlugInterFace();
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int ScreenToClient(long ola, long hwnd, int x, int y);

long instance = CreateCOLAPlugInterFace();
ScreenToClient(instance, hwnd, 100, 200);
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
ola.ScreenToClient(instance, hwnd, 100, 200)
