Button1Click與FormCreate傚果不一樣,不知為何？還有就是有沒有其他的方法實現這種傚果,請指教!代碼如下：
---------------------------------------------------------------------
unit Unit1; interface uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, ExtCtrls, jpeg; type
TForm1 = class(TForm)
Button1: TButton;
MiniBgPanel: TPanel;
ScrollBox1: TScrollBox;
ScrollBox2: TScrollBox;
Panel1: TPanel;
Image1: TImage;
procedure Button1Click(Sender: TObject);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
procedure MYCLICK (Sender: TObject);
end; var
Form1: TForm1;
cnpages : integer = 0;
var
MiniPanel1:TPanel;
MiniImage1:TImage; implementation {$R *.dfm} procedure TForm1.Button1Click(Sender: TObject);
begin
Inc(cnpages); MiniPanel1 := TPanel.Create(self);
MiniPanel1.Parent :=MiniBgPanel;
MiniPanel1.Visible := true;
MiniPanel1.Align := alNone; MiniPanel1.Name := 'MiniPanel' INTTOSTR(cnpages);
MiniPanel1.Caption := '';
MiniPanel1.Left := 8;
MiniPanel1.Top :=21 (cnpages-1)*135;
MiniPanel1.Height:= 134;
MiniPanel1.Width:=174; MiniPanel1.Color := clAqua; MiniImage1:= TImage.Create(self);
MiniImage1.OnClick:= MYCLICK;
MiniImage1.Name := 'MiniImage1' INTTOSTR(cnpages);
MiniImage1.Left:=7;
MiniImage1.Top := 8 (cnpages-1)*135;
MiniImage1.Height:=120;
MiniImage1.Width:=160; MiniImage1.Parent:=MiniPanel1;
MiniImage1.Visible:=true; MiniImage1.Canvas.Brush.Color := clWhite ;
MiniImage1.Canvas.Brush.Style := bsSolid;
MiniImage1.Canvas.FillRect(MiniImage1.ClientRect);
end; procedure TForm1.MYCLICK (Sender: TObject);
BEGIN
IF Sender IS TIMAGE THEN
BEGIN
SHOWMESSAGE((Sender AS TIMAGE).Name);
END;
END; procedure TForm1.FormCreate(Sender: TObject);
begin
Image1.Canvas.Brush.Color := clWhite ;
Image1.Canvas.Brush.Style := bsSolid;
Image1.Canvas.FillRect(Image1.ClientRect);
Inc(cnpages); MiniPanel1 := TPanel.Create(self);
MiniPanel1.Parent :=MiniBgPanel;
MiniPanel1.Visible := true;
MiniPanel1.Align := alNone; MiniPanel1.Name := 'MiniPanel' INTTOSTR(cnpages);
MiniPanel1.Caption := '';
MiniPanel1.Left := 8;
MiniPanel1.Top :=21 (cnpages-1)*135;
MiniPanel1.Height:= 134;
MiniPanel1.Width:=174; MiniPanel1.Color := clAqua; MiniImage1:= TImage.Create(self);
MiniImage1.OnClick:= MYCLICK;
MiniImage1.Name := 'MiniImage1' INTTOSTR(cnpages);
MiniImage1.Left:=7;
MiniImage1.Top := 8 (cnpages-1)*135;
MiniImage1.Height:=120;
MiniImage1.Width:=160; MiniImage1.Parent:=MiniPanel1;
MiniImage1.Visible:=true; MiniImage1.Canvas.Brush.Color := clWhite ;
MiniImage1.Canvas.Brush.Style := bsSolid;
MiniImage1.Canvas.FillRect(MiniImage1.ClientRect); end; end.
