c++ - 从 Window Rect 计算客户端大小和位置

Question

如何使用 window rect 获取客户端大小和位置？这可能吗？

Answer 1

不确定您到底想找出什么。也许尝试这样的事情:

#include <iostream>
#include <windows.h>

int main()
{
    RECT r;
    HWND h = GetConsoleWindow(); // or whatever window needed

    GetWindowRect(h, &r);
    std::cout << "Relative Client X,Y: " << r.left << "," << r.top << std::endl;
    std::cout << "Relative Client W,H: " << r.right - r.left << "," << r.bottom - r.top << std::endl;

    GetClientRect(h, &r);
    std::cout << "Client X,Y: " << r.left << "," << r.top << std::endl;
    std::cout << "Client W,H: " << r.right - r.left << "," << r.bottom - r.top << std::endl;
}

例如:

Relative Client X,Y: 100,100
Relative Client W,H: 947,594
Client X,Y: 0,0
Client W,H: 910,552

和/或如果你想获得客户区相对于屏幕的位置，你可以使用ClientToScreen功能。例如:

#include <windows.h>

int main()
{
    HWND h = GetConsoleWindow(); // or provided HWND
    POINT p{}; // defaulted to 0,0 which is always left and top of client area

    ClientToScreen(h, &p);
    SetCursorPos(p.x, p.y); // places cursor to the 0,0 of the client
}
