Error: Identifier not found
(1/1)
sardu:
Ciao a tutti,
sto cercando di fare un porting su lazarus di un sofware ma spesso mi "pianto" in cose apparentementi banali tipo questa:
Creando un pulsante che chiama una procedura, se questa vuole scrivere nella statusbar mi da l'errore:
/Error: Identifier not found "StatusBar1"
Stesso errore se volessi scrivere in un Tmemo etc.
Cosa mi sono perso?
Grazie per un eventuale aiuto.
--- Code: ---unit Unit1;
{$mode objfpc}{$H+}
interface
uses
Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, ComCtrls,
StdCtrls;
type
{ TForm1 }
TForm1 = class(TForm)
Button1: TButton;
StatusBar1: TStatusBar;
procedure Button1Click(Sender: TObject);
private
{ private declarations }
public
{ public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.lfm}
{ TForm1 }
procedure Prova();
begin
StatusBar1.Panels[1].Text := ' Prova '; //Error: Identifier not found "StatusBar1"
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
StatusBar1.Panels[1].Text := ' Funziona ';
Prova();
end;
end.
--- End code ---

Not sure if you understand English ...
StatusBar1 is defined withing TForm1 and you use it in a function that is outside the scope of TForm1, which is why it won't find it.
If you would define a function in the TForm1, called TForm1.Prova(), it will work much better.
