问题是Inno Setup中的所有标签都是TStaticText,这是不透明的.所以你必须用TLabel替换所有.而且有很多.它们由Inno Setup管理.所以你不得不不断地将新的TStaticText更新为Inno Setup设置为原始TLabel的值.它甚至可能是不可能的.

实际上,可以在您的问题中创建一个页面.但仅仅是因为没有标准的Inno Setup标签.但你不能隐藏所有这些.

procedure InitializeWizard();
var
  BackImage: TBitmapImage;
begin
  { Hide top panel }
  WizardForm.MainPanel.Visible := False;

  { Adjust "select dir" page controls for a stretched inner page size }
  WizardForm.DirEdit.Left := WizardForm.DirEdit.Left + WizardForm.InnerNotebook.Left;
  WizardForm.DirEdit.Top := WizardForm.DirEdit.Top + WizardForm.InnerNotebook.Top;
  WizardForm.DirBrowseButton.Left :=
    WizardForm.DirBrowseButton.Left + WizardForm.InnerNotebook.Left;
  WizardForm.DirBrowseButton.Top :=
    WizardForm.DirBrowseButton.Top + WizardForm.InnerNotebook.Top;

  { Hide non-transparent labels }    
  WizardForm.DiskSpaceLabel.Visible := False;
  WizardForm.SelectDirBrowseLabel.Visible := False;
  WizardForm.SelectDirLabel.Visible := False;

  { Stretch the outer page across whole form }
  WizardForm.OuterNotebook.Width := WizardForm.ClientWidth;
  WizardForm.OuterNotebook.Height := WizardForm.ClientHeight;

  { Stretch the inner page across whole outer page }
  WizardForm.InnerNotebook.Left := 0;
  WizardForm.InnerNotebook.Top := 0;
  WizardForm.InnerNotebook.Width := WizardForm.OuterNotebook.ClientWidth;
  WizardForm.InnerNotebook.Height := WizardForm.OuterNotebook.ClientHeight;

  { Put buttons on top of the page (image) }
  WizardForm.BackButton.BringToFront()
  WizardForm.NextButton.BringToFront();
  WizardForm.CancelButton.BringToFront();

  { Add a background image }    
  BackImage := TBitmapImage.Create(WizardForm);
  BackImage.Parent := WizardForm.SelectDirPage;
  BackImage.Top := 0;
  BackImage.Left := 0;  
  { ... }
  BackImage.Bitmap.LoadFromFile(...);
end;
