如何在面板中显示Delphi表单？

Question

我试图按照http://docwiki.embarcadero.com/CodeExamples/XE7/en/FMXEmbeddedForm_(Delphi)的例子,但我遇到了TCustomForm的孩子的第一个问题,这显然是只读的,所以我发表了评论说出来,放在ArgForm.Parent:= ArgParent;代替,但我仍然只得到一个空的屏幕并不能看到那些在我的第二个表格的按钮.

我的主要表格的代码是:

unit Unit1;

interface

uses
  System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
  FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMX.StdCtrls, Unit2;

type
  TForm1 = class(TForm)
    Panel1: TPanel;
    procedure FormCreate(Sender: TObject);
    procedure EmbedForm(ArgParent : TControl; ArgForm : TCustomForm);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
  Form2: TForm2;

implementation

{$R *.fmx}

procedure TForm1.FormCreate(Sender: TObject);
begin
  Form2:= TForm2.Create(Self);
  EmbedForm(Panel1, Form2);
end;

procedure TForm1.EmbedForm(ArgParent: TControl; ArgForm: TCustomForm);
begin
  //while ArgForm.ChildrenCount>0 do
  //begin
    //ArgForm.Children[0]:= ArgParent);
  //end;
  ArgForm.Parent:= ArgParent;
end;
end.

放在我的主窗体面板中的表单代码是:

unit Unit2;

interface

uses
  System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
  FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMX.StdCtrls;

type
  TForm2 = class(TForm)
    Button1: TButton;
    Button2: TButton;
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form2: TForm2;

implementation

{$R *.fmx}

end.

您只需要使用与示例中编写的代码完全相同的代码.你写了:

while ArgForm.ChildrenCount>0 do
  ArgForm.Children[0]:= ArgParent;

但是您链接到的示例中的代码读取:

while ArgForm.ChildrenCount>0 do
  ArgForm.Children[0].Parent := ArgParent;

从好的方面来说,你至少已经纠正了嵌入的拼写.
