这是我的问题的延续:如何在面板中显示 Delphi 表单?
我想使用表单全局变量将其嵌入到面板中以现在显示它,但它只创建要嵌入的表单,没有它的按钮。
在可执行文件的代码中,我首先创建要嵌入的表单,然后创建要嵌入的表单,如下所示:
program Project1;
uses
System.StartUpCopy,
FMX.Forms,
Unit1 in 'Unit1.pas' {Form1},
Unit2 in 'Unit2.pas' {Form2};
{$R *.res}
begin
Application.Initialize;
Application.CreateForm(TForm2, Form2);
Application.CreateForm(TForm1, Form1);
Application.Run;
end.
主窗体的代码是:
unit Unit1;
interface
uses
System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMX.StdCtrls;
type
TForm1 = class(TForm)
Label1: TLabel;
Panel1: TPanel;
procedure EmbedForm(ArgParent : TControl; ArgForm : TCustomForm);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.fmx}
uses Unit2;
procedure TForm1.FormCreate(Sender: TObject);
begin
EmbedForm(Panel1, Form2);
end;
procedure TForm1.EmbedForm(ArgParent: TControl; ArgForm: TCustomForm);
begin
while ArgForm.ChildrenCount>0 do
begin
ArgForm.Children[0].Parent:= ArgParent;
end;
end;
end.
要嵌入的表单的代码是:
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)
Button2: TButton;
Button1: TButton;
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form2: TForm2;
implementation
{$R *.fmx}
end.
