我需要制作一个程序,用于输入和显示产品的信息(品牌名称,内容,质量和库存量)。为什么我的输入框不按顺序显示?
问题:即使编写了代码以便按顺序显示代码,但这段代码中的输入框并没有按顺序完整显示。输入框的顺序是:“内容”,“质量”,“库存”,“品牌名称”,实际上应该是“品牌名称”,“内容”,“质量”,“库存”(这些是输入框的标题)。
- 我想,这可能是源(向下滚动计划的其余部分):
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: - 所有的数据都会在那里打算去
,因此输入框的顺序根本不影响程序。我只想知道是否有办法使输入框按顺序显示。
- 这是一项任务,但输入框的顺序不会计算标记。
整个代码:
应用:
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.
我的类:
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.
