我需要製作一個程序,用於輸入和顯示產品的信息(品牌名稱,內容,質量和庫存量)。爲什麼我的輸入框不按順序顯示?
問題:即使編寫了代碼以便按順序顯示代碼,但這段代碼中的輸入框並沒有按順序完整顯示。輸入框的順序是:「內容」,「質量」,「庫存」,「品牌名稱」,實際上應該是「品牌名稱」,「內容」,「質量」,「庫存」(這些是輸入框的標題)。
- 我想,這可能是源(向下滾動計劃的其餘部分):
StrObj := TProducts.Create(Inputbox('Brand name', 'Input the brand name', ''),Inputbox('Contents', 'Input the contents', ''), StrToInt(Inputbox('Mass', 'Input the mass', '')), StrToInt(Inputbox('Stock', 'Input the number in stock', '')));
注: - 所有的數據都會在那裏打算去
,因此輸入框的順序根本不影響程序。我只想知道是否有辦法使輸入框按順序顯示。
- 這是一項任務,但輸入框的順序不會計算標記。
整個代碼:
應用:
unit TProducts_U;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, ComCtrls, TProducts_class;
type
TForm1 = class(TForm)
btnResult: TButton;
redOut: TRichEdit;
procedure btnResultClick(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.btnResultClick(Sender: TObject);
var StrObj : TProducts;
begin
StrObj := TProducts.Create(Inputbox('Brand name', 'Input the brand name', ''),Inputbox('Contents', 'Input the contents', ''), StrToInt(Inputbox('Mass', 'Input the mass', '')), StrToInt(Inputbox('Stock', 'Input the number in stock', '')));
redOut.Lines.Add(StrObj.toString);
end;
end.
我的類:
unit TProducts_class;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, Math;
type
TProducts = class
private
fBname, fContents : string;
fMass, fNum : integer;
public
Constructor Create; overload;
Constructor Create(Bname, contents : string; mass, num : integer); overload;
Function toString : string;
end;
implementation
{ TProducts }
constructor TProducts.Create;
begin
fBname := '';
fContents := '';
fMass := 0;
fNum := 0;
end;
constructor TProducts.Create(Bname, contents: string; mass, num: integer);
begin
fBname := Bname;
fContents := contents;
fMass := mass;
fNum := num;
end;
function TProducts.toString: string;
begin
result := 'Brand Name is : ' + fBname + #13 +
'Contents is : ' + fContents + #13 +
'Mass is : ' + IntToStr(fMass) + #13 +
'We have ' + IntToStr(fNum) + ' in stock';
end;
end.
除了不被不正確的* *得多更具可讀性。 :-) –
