这是我的问题的延续:How can I display a Delphi form in a panel?
我想使用表单全局变量将其嵌入到面板中以便立即显示它,但它只创建要嵌入的表单,而不是它的按钮。
在可执行文件的代码中,我创建了首先嵌入的表单,以及我希望将其嵌入第二个表单,如下所示:
program Project1;
uses
System.StartUpCopy,
FMX.Forms,
Unit1 in 'Unit1.pas' {Form1},
Unit2 in 'Unit2.pas' {Form2};
{$R *.res}
begin
Application.Initialize;
Application.CreateForm(TForm2, Form2);
Application.CreateForm(TForm1, Form1);
Application.Run;
end.
主要表格的代码是:
unit Unit1;
interface
uses
System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMX.StdCtrls;
type
TForm1 = class(TForm)
Label1: TLabel;
Panel1: TPanel;
procedure EmbedForm(ArgParent : TControl; ArgForm : TCustomForm);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$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.

我以前做过这种方式,以避免必须遍历ArgForm的所有孩子,就是在ArgForm上有一个“主容器”,它有你需要的所有孩子。 我如何设置它是
项目来源:
program Project1;
uses
System.StartUpCopy,
FMX.Forms,
Unit1 in 'Unit1.pas' {ParentForm},
Unit2 in 'Unit2.pas' {ArgForm};
{$R *.res}
begin
Application.Initialize;
Application.CreateForm(TParentForm, ParentForm);
Application.CreateForm(TArgForm, ArgForm);
Application.Run;
end.
父母表格代码:
unit Unit1;
interface
uses
System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs,unit2,
FMX.StdCtrls;
type
TParentForm = class(TForm)
Panel1: TPanel;
procedure FormShow(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
ParentForm: TParentForm;
implementation
{$R *.fmx}
procedure TParentForm.FormShow(Sender: TObject);
begin
ArgForm.Children[0].Parent:=Self.Panel1;
end;
end.
ArgForm代码:
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,
FMX.Layouts;
type
TArgForm = class(TForm)
Layout1: TLayout;
Button1: TButton;
Button2: TButton;
private
{ Private declarations }
public
{ Public declarations }
end;
var
ArgForm: TArgForm;
implementation
{$R *.fmx}
end.
也许其他人可以回答,但在我看来按钮没有在创建中显示的原因是,当时没有创建控件?
