Question

我正在做一个项目，如果您按下图像，则图像将通过编码导致再次按下按钮。

我尝试了Image.click;，Image.OnClick := Imageclick;

procedure TForm1.RandomRekenaar;
var
  z: integer;
begin
  z := 0;
  if (rgpSpelTipe.ItemIndex = 0) and (rgpSpelers.ItemIndex = 2) then
  begin
    z := Random(16 - 1 + 1);
    case z of
      1:
          if Prent41.Visible <> False 
          then Prent41.OnClick := Prent41Click
          else RandomRekenaar;
      2:
        begin
          if Prent42.Visible <> False then
          begin
            Prent42.Click;
          end
          else
          begin
            RandomRekenaar;
          end;
        end;
      3:
        begin
          if Prent43.Visible <> False then
          begin
            Prent43.Click;
          end
          else
          begin
            RandomRekenaar;
          end;
        end;
      4:
        begin
          if Prent44.Visible <> False then
          begin
            Prent44.Click;
          end
          else
          begin
            RandomRekenaar;
          end;
        end;
      5:

          begin
            Prent46.Click;
          end
          else
          begin
            RandomRekenaar;
          end;
        end;
      7:
        begin

Answer 1

尝试更多类似的方法：

var
  Images: array[0..15] of TImage;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Images[0] := Prent41;
  Images[1] := Prent42;
  ...
  Images[15] := Prent416;

  { or:
  for I := 0 to 15 do
    Images[I] := TImage(FindComponent('Prent4'+IntToStr(I+1)));
  }
end;

function TForm1.RandomImage: TImage;
var
  VisibleImages: array[0..15] of TImage;
  I, Count: Integer;
begin
  Result := nil;
  Count := 0;
  for I := 0 to 15 do
  begin
    if Images[I].Visible then
    begin
      VisibleImages[Count] := Images[I];
      Inc(Count);
    end;
  end;
  if Count > 0 then
    Result := VisibleImages[Random(Count)];
end;

procedure TForm1.RandomRekenaar;
var
  Image: TImage;
begin
 if (rgpSpelTipe.ItemIndex = 0) and (rgpSpelers.ItemIndex = 2) then
 begin
   Image := RandomImage;
   if Image <> nil then
     Image.Click; // or Image.OnClick(Image);
  end;
end;

Answer 2

您可以执行以下操作：

ImageClick(Image);

无论如何，我建议定义一个单独的函数：

procedure TForm1.SelectRandomImage();
begin
  //...
end;


procedure TForm1.ImageClick(Sender : TObject);
begin
  SelectRandomImage();
end;

这样，您可以直接调用SelectRandomImage过程，我认为代码将更具可读性。
