FMX 中的运行时设计？

Question

There are components that let you edit forms at run-time in VCL.

Is run-time editing of forms possible in FMX? (I want the ability to modify forms inside of mobile apps.)

Answer 1

To answer your second question first: Yes it is possible to modify FMX forms and its controls at run time. For your second question: AFAIK there are no components that would you help with that task. If you want to go and make your own form designer, be aware that the seemingly highly suitable TSelection component is very buggy up until XE7 and still has some flaws in XE 8 - you better make your own.

Answer 2

Yes, exactly as in VCL, but most object property will be different. Following sample create new Button on main form.

unit ufmMain;

interface

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

type
  TfmMain = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
    MyButton1: TButton;
  end;

var
  fmMain: TfmMain;

implementation

{$R *.fmx}

procedure TfmMain.FormCreate(Sender: TObject);
begin
  MyButton1 := TButton.Create(fmMain);
  MyButton1.Parent := fmMain;
  MyButton1.Position.X := 10;
  MyButton1.Position.Y := 10;
  MyButton1.Width := 50;
  MyButton1.Height := 10;
  MyButton1.Text := 'TEXT';
end;

end.
