如何检查文本光标是否显示

Question

如何使用 Windows API 检查文本光标是否存在于特定的 HANDLE 中

#include <window.h>
int main()
{
 if (text_cursor)
 {
  //do stuff
 }

 return 0;
}

Answer 1

要检查特定窗口中是否存在文本光标（由其 HANDLE 标识），您可以使用 Windows API 函数，特别是 GetFocus 函数。例如-

#include <Windows.h>

int main() {
    // Obtain the handle of the window that has the input focus
    HWND focusedWindow = GetForegroundWindow();

    // Check if the focused window is the specific window you are interested in
    if (focusedWindow == YOUR_SPECIFIC_HANDLE) {
        // The text cursor is present in the specific window
        // Perform your actions here
    }

    return 0;
}

将 YOUR_SPECIFIC_HANDLE 替换为您要检查的窗口的实际句柄。
