Create a new TUniForm class

[JDDEV]

Hi,

I would like to create a new component with a inheritance from TuniForm class.

On Delphi IDE the new component assistant interface doesn't permit to select TuniForm class !

Is it possible do to inheritance  on this object class ?

 

Thanks

Sorry....i've just fond the solution myself !

1) I've created a new "application form" with the IDE

2) I've customized properties et functions of this form

3) I've used this new class for the inheritance of my main application form

that's not work anymore :(

It was working the first time....but when i the project and then re-open it...there are warning dialogs and a message "Read error form UniMainForm".

That is the code of my First unit :

unit UniMainForm;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics,  Controls, Forms, uniGUITypes, uniGUIAbstractClasses,  uniGUIClasses, uniGUIForm
  , uDefUser {a unit to manager user};

type
  TUniMainForm = class(TUniForm)
    procedure UniFormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
    user:TUser;
  end;

implementation

{$R *.dfm}

uses
  UniGUIVars, MainModule, uniGUIApplication;

procedure TUniMainForm.UniFormCreate(Sender: TObject);
begin
  initUser(user, True);
end;

initialization
  RegisterMainFormClass(TUniMainForm);

end.

 

That is the code of my 2d unit :

unit Main;

interface

    bNeedConnexion:boolean;
    procedure GoAction(id:byte; bRefresh:boolean=False);
  public
    { Public declarations }
    function GetIdAction : byte;
  end;

function MainForm: TMainForm;

implementation
{$R *.dfm}

uses
  UniGUIVars, MainModule, UniGUIApplication, ServerModule;

The program work fine (compilation  + runing), but i can't open the "Main.pas" unit on Delphi without error : "UniMainForm" not defined ?

What is wrong in Delphi ???

[JDDEV]

I find the problem !

A bad Copy/Paste of the class name in the  .DFM file !
