通过Win API 模拟鼠标点击,使C# Java交互 (PART.2 Java部分)
Java部分:
调用:
ArrayList
<
QueueItem
>
li
=
new
ArrayList
<
QueueItem
>
();
li.add(
new
QueueItem(
"
WindowsForms10.Window.8.app3
"
,
"
采集系统
"
));
li.add(
new
QueueItem(
"
WindowsForms10.BUTTON.app3
"
,
"
选项
"
));
int
result
=
NativeWin32.ClickOnWindow(li);
System.
out
.print(result);
PINVOKE封装采用 NativeCall [
