推荐答案

尝试：

#include <FMX.Platform.Win.hpp>

void __fastcall TMyForm::DoSomething()
{
    TWinWindowHandle *ThisHandle = WindowHandleToPlatform(this->Handle);
    if (ThisHandle != NULL)
    {
        HWND hWnd = ThisHandle->Wnd;
        if (ThisWnd != NULL)
        {
            // use ThisWnd as needed...
        }
    }
}

或使用 FormToHWND（） > WindowHandleToPlatform（）内部）：

Or use FormToHWND() instead (which uses WindowHandleToPlatform() internally):

#include <FMX.Platform.Win.hpp>

void __fastcall TMyForm::DoSomething()
{
    HWND ThisWnd = FormToHWND(this);
    if (ThisWnd != NULL)
    {
        // use ThisWnd as needed...
    }
}

无论哪种方式，请记住这些功能是特定的Windows。如果你想要跨平台的东西，你必须找到另一个解决方案。

Either way, keep in mind that these functions are specific Windows. If you want something that is cross-platform, you will have to find another solution.
