如何在面板中显示 Delphi 表单?

How can I display a Delphi form in a panel?

我试着按照 http://docwiki.embarcadero.com/CodeExamples/XE7/en/FMXEmbeddedForm_(Delphi) 的例子,但我遇到了 TCustomForm 的子项的第一个问题,它们显然是只读的,所以我将其注释掉并放入 ArgForm.Parent:= ArgParent;相反,但我仍然只是看到一个空白屏幕,看不到第二个表单中的按钮。

我的主窗体代码是:

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.

放置在我的主窗体面板中的窗体代码是:

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.

您只需要完全按照示例中编写的代码使用即可。您写道:

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

但是您链接到的示例中的代码显示为:

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

从好的方面来说,您至少更正了 embed 的拼写。
