INNO设置：如何调整组件内窗口

Question

我正在尝试创建自定义组件窗口。到目前为止，我已经在stackoverflow上找到了一些代码，它允许我设置组件窗口的外窗高度。我的问题是实际的组件选择框不会随之增长，就像我有一个大窗口但仍然是一个小组件选择框。

我的问题图片：

希望有人能帮助我。

我的代码就是这个

var
  DefaultTop, 
  DefaultLeft, 
  DefaultHeight,
  DefaultBackTop, 
  DefaultNextTop, 
  DefaultCancelTop,
  DefaultBevelTop, 
  DefaultOuterHeight: Integer;

const 
  LicenseHeight = 600;
  LicenseWidth = 600;

procedure InitializeWizard();
begin
  DefaultTop := WizardForm.Top;
  DefaultLeft := WizardForm.Left;
  DefaultHeight := WizardForm.Height;
  DefaultBackTop := WizardForm.BackButton.Top;
  DefaultNextTop := WizardForm.NextButton.Top;
  DefaultCancelTop := WizardForm.CancelButton.Top;
  DefaultBevelTop := WizardForm.Bevel.Top;    
end;

procedure CurPageChanged(CurPageID: Integer);
begin
  if CurPageID = wpSelectComponents then
  begin
    WizardForm.Top := DefaultTop - (LicenseHeight - DefaultHeight) div 2;
    WizardForm.Height := LicenseHeight;
    WizardForm.Width := LicenceWidth;
    WizardForm.OuterNotebook.Height := WizardForm.OuterNotebook.Height + (LicenseHeight - DefaultHeight);
    WizardForm.CancelButton.Top := DefaultCancelTop + (LicenseHeight - DefaultHeight);
    WizardForm.NextButton.Top := DefaultNextTop + (LicenseHeight - DefaultHeight);
    WizardForm.BackButton.Top := DefaultBackTop + (LicenseHeight - DefaultHeight);
    WizardForm.Bevel.Top := DefaultBevelTop + (LicenseHeight - DefaultHeight);
  end
  else 
  begin
    WizardForm.Top := DefaultTop;
    WizardForm.Left := DefaultLeft;
    WizardForm.Height := DefaultHeight;
    WizardForm.OuterNotebook.Height := DefaultOuterHeight;
    WizardForm.CancelButton.Top := DefaultCancelTop;
    WizardForm.NextButton.Top := DefaultNextTop;
    WizardForm.BackButton.Top := DefaultBackTop;
    WizardForm.Bevel.Top := DefaultBevelTop;
  end;
end;
