推荐答案

VCL框架未公开此内容。相反，您需要使用Win32 API。您需要的功能是 GetWindowPlacement 。

This is not exposed by the VCL framework. Instead you need to dip into the Win32 API. The function you need is GetWindowPlacement.

var
  WindowPlacement: TWindowPlacement;
....
WindowPlacement.length := SizeOf(WindowPlacement);
Win32Check(GetWindowPlacement(Form.Handle, WindowPlacement));

您需要的信息可以在 WindowPlacement 结构。请注意，坐标是相对于工作区域而不是屏幕报告的。

The information you need can be found in the WindowPlacement struct. Do beware that the coordinates are reported with respect to the work area rather than the screen.

通常，您需要此信息，以便以后可以恢复它。使用 SetWindowPlacement 可以做到这一点。

Generally you want this information so that you can restore it at a later date. Use SetWindowPlacement to do that.
