How to reduce the line spacing between two input boxes on Inno Setup TInputQueryWizardPage (CreateInputQueryPage)

Question

I have a TInputQueryWizardPage page with 8 user inputs. The wizard page has been increased but still all the values are not visible. Is there a way to reduce the line spacing between two values so that all the values will be displayed with the current wizard size?

Use TInputQueryWizardPage.Edits and TInputQueryWizardPage.PromptLabels to access the controls and re-locate them as you need:

[Code]

procedure ReducePromptSpacing(Page: TInputQueryWizardPage; Count: Integer; Delta: Integer);
var
  I: Integer;
begin
  for I := 1 to Count - 1 do
  begin
    Page.Edits[I].Top := Page.Edits[I].Top - Delta * I;
    Page.PromptLabels[I].Top := Page.PromptLabels[I].Top - Delta * I;
  end;
end;

procedure InitializeWizard();
var
  Page: TInputQueryWizardPage;
begin
  Page := CreateInputQueryPage(wpWelcome,
    'Personal Information', 'Who are you?',
    'Please specify your name and the company for whom you work, then click Next.');

  Page.Add('Prompt 1:', False);
  Page.Add('Prompt 2:', False);
  Page.Add('Prompt 3:', False);
  Page.Add('Prompt 4:', False);
  Page.Add('Prompt 5:', False);

  ReducePromptSpacing(Page, 5, ScaleY(10));
end;

Standard layout:
