函数简介
获取鼠标图标。
接口名称
GetCursorImageDLL调用
long GetCursorImage(long ola);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。 |
示例
SDK 调用
cpp
#include "OLAPlugServer.h"
OLAPlugServer ola;
long handle = ola.GetCursorImage();csharp
using OLAPlug;
var ola = new OLAPlugServer();
long handle = ola.GetCursorImage();python
from OLAPlugServer import OLAPlugServer

long handle = ola.GetCursorImage();cpp
var ola = com("OlaPlug.OlaSoft")
var handle = ola.GetCursorImage()vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")

.局部变量 ola, OLAPlug
ola.创建 ()

变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
长整数 handle = ola.GetCursorImage()cpp

long ptr = GetCursorImage(instance);
if (ptr != 0) {
char buffer[512] = {0};
GetStringFromPtr(ptr, buffer, sizeof(buffer));
FreeStringPtr(ptr);
}csharp

FreeStringPtr(ptr);

}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()
ptr = ola.GetCursorImage(instance)
if ptr:
buf = create_string_buffer(512)
ola.GetStringFromPtr(ptr, buf, 512)
ola.FreeStringPtr(ptr)
result = buf.value.decode("utf-8")返回值
长整数型:OLAImage对象的地址。返回 0 表示失败。
注意事项
- 图片使用完后需要调用 FreeImagePtr 接口进行释放。
