在Inno设置向导的顶部面板中显示图像，而不是页面标题和说明

Question

我想在向导顶部的空间中放置一个图像，如图所示。并隐藏页面标题和说明。

Answer 1

用图片覆盖MainPanel并隐藏其所有其他组件（WizardSmallBitmapImage，PageDescriptionLabel和PageNameLabel）：

[Files]
Source: "rainbow.bmp"; Flags: dontcopy

[Code]

procedure InitializeWizard();
var
  BitmapImage: TBitmapImage;
begin
  ExtractTemporaryFile('rainbow.bmp');
  BitmapImage := TBitmapImage.Create(WizardForm);
  BitmapImage.Parent := WizardForm.MainPanel;
  BitmapImage.Width := WizardForm.MainPanel.Width;
  BitmapImage.Height := WizardForm.MainPanel.Height;
  BitmapImage.Stretch := True;
  BitmapImage.AutoSize := False;
  BitmapImage.Bitmap.LoadFromFile(ExpandConstant('{tmp}\rainbow.bmp'));

  WizardForm.WizardSmallBitmapImage.Visible := False;
  WizardForm.PageDescriptionLabel.Visible := False;
  WizardForm.PageNameLabel.Visible := False;
end;
