我在滚动框中创建了7个动态按钮。每行只需要有2个按钮(按钮数量可能会有变化),但下面代码的结果显示第一行有2个按钮,但所有其余按钮在第2行,我应该如何将其固定为2个按钮1行?

procedure TForm1.CreateDynamicBtn2;
var
   abtn: TBitBtn;
   i, j, iNum, iCount : integer;
begin
  if ScrollBox2.ControlCount > 0 then begin
       for j := ScrollBox2.ControlCount - 1 downto 0 do begin
          with ScrollBox2.Controls[j] AS TBitBtn do begin
            Free;
          end;
       end;
    end;
  iCount := 0;
  for i := 0 to 6 do begin
    iNum := i + 1;
    abtn := TBitBtn.Create(self);
    abtn.Parent := ScrollBox2;
    abtn.Visible := True;
    abtn.Caption := 'dynamic' + IntToStr(i);

    if iNum*abtn.Width > (iCount+2)*abtn.Width then begin
       iCount := iCount + 1;
       abtn.Left := (iCount * abtn.Width) - abtn.Width;
       abtn.Top  := abtn.Height;
    end else begin
       abtn.Left := i * abtn.Width;
       abtn.Top  := 0;
    end;
  end;
end; 

1 个答案:

答案 0 :(得分:3)

因为你让事情太复杂了?

abtn.Left := (i mod 2) * abtn.Width;
abtn.Top := Trunc((i div 2)) * abtn.Height;

应该很好地完成这个伎俩。
