在C ++ / CLI中获取GetCursorPos之后的相对位置？

问题描述

截至目前，我已成功获得x和y坐标。



在面板代码中。



POINT cursorPos;

GetCursorPos（& cursorPos）;

int x;

int y;

x = cursorPos.x;

y = cursorPos.y;

cout<< x<< endl;

cout<< y<< endl;

然而，我得到的x和y坐标是全局的，也就是说，不在我希望得到坐标的面板内。



我明白需要ClientToScreen将x和y坐标更改为相对位置，但我如何在C ++ / CLR中这样做？



因为ClientToScreen需要一个句柄，这在C ++ / CLR中没有引入（请原谅我，如果这个点我错了）。谢谢:)



更新：我尝试将我的面板投射到hwnd中，但仍然无法正常工作。



HWND hwnd = static_cast< hwnd>（this-> panel1-> Handle.ToPointer（））;

So as of now, I've managed to successfully get the x and y coordinates.

Inside the panel code.

POINT cursorPos;
GetCursorPos(&cursorPos);
int x;
int y;
x = cursorPos.x;
y = cursorPos.y;
cout << x << endl;
cout << y << endl;
However, the x and y coordinate that I got is global, aka, not within a panel that I want to get my coordinates from.

I do understand that ClientToScreen is required to change the x and y coordinate to its relative placing, but how do i do that in C++/CLR?

Because ClientToScreen requires a handle, which is not introduced in C++/CLR (Pardon me if im wrong about this point). Thanks :)

Update: I tried casting my panel into a hwnd, but still its not working.

HWND hwnd = static_cast<hwnd>(this->panel1->Handle.ToPointer());
