提示: SetParent 应该 Windows.SetParent, 因为 TForm 的父类有同名方法.


//声明:

{获取父窗口句柄}
GetParent(hWnd: HWND): HWND; {指定父窗口}
SetParent(
  hWndChild: HWND;    {子句柄}
  hWndNewParent: HWND {父句柄}
): HWND;              {成功返回原父窗口句柄; 失败返回 0} {移动窗口}
MoveWindow(
  hWnd: HWND;              {窗口句柄}
  X, Y: Integer;            {位置}
  nWidth, nHeight: Integer; {大小}
  bRepaint: BOOL            {True 表示刷新; False 表示不刷新}
): BOOL;

//举例:
unit Unit1; interface uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ExtCtrls; type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  end; var
  Form1: TForm1; implementation {$R *.dfm} procedure TForm1.Button1Click(Sender: TObject);
begin
  if GetParent(Edit1.Handle)=Handle then
  begin
    Windows.SetParent(Edit1.Handle, Button1.Handle);
    MoveWindow(Edit1.Handle, ,, Edit1.Width, Edit1.Height, True);
  end else begin
    Windows.SetParent(Edit1.Handle, Self.Handle);
    MoveWindow(Edit1.Handle, ,, Edit1.Width, Edit1.Height, True);
  end;
end; end.

GetParent - 获取指定窗口的父窗口句柄
IsChild - 判断两个窗口是不是父子关系
