Larger "Select Components" page in Inno Setup

Question

I have been trying for a while to make the "Select Components" page larger as in the picture below, including the components inner-window (the white one), because I have many components ... and it gets easier to select when it is larger window. If anyone could tell if that's even possible, please give me a hint or point me in a direction.

Based on your original script I made the following changes. For storing original positions (top and height values) I have used an array of integers and made two general procedures for storing the current positions and for restoring them.

The restoring procedure has the HeightOffset parameter, where you can specify the value, by which all the values from the input array of integers will be increased before they are passed to the wizard form component properties. Except that, I've declared a separate flag indicating that wizard form has modified size.

I used all of this because it improves readability of the script and it's easily extendable for other pages:

[Code]

type
  TPositionStorage = array of Integer;

var
  CompPageModified: Boolean;
  CompPagePositions: TPositionStorage;

procedure SaveComponentsPage(out Storage: TPositionStorage);
begin
  SetArrayLength(Storage, 10);

  Storage[0] := WizardForm.Height;
  Storage[1] := WizardForm.NextButton.Top;
  Storage[2] := WizardForm.BackButton.Top;
  Storage[3] := WizardForm.CancelButton.Top;
  Storage[4] := WizardForm.ComponentsList.Height;
  Storage[5] := WizardForm.OuterNotebook.Height;
  Storage[6] := WizardForm.InnerNotebook.Height;
  Storage[7] := WizardForm.Bevel.Top;
  Storage[8] := WizardForm.BeveledLabel.Top;
  Storage[9] := WizardForm.ComponentsDiskSpaceLabel.Top;
end;

procedure LoadComponentsPage(const Storage: TPositionStorage;
  HeightOffset: Integer);
begin
  if GetArrayLength(Storage) <> 10 then
    RaiseException('Invalid storage array length.');

  WizardForm.Height := Storage[0] + HeightOffset;
  WizardForm.NextButton.Top := Storage[1] + HeightOffset;
  WizardForm.BackButton.Top := Storage[2] + HeightOffset;
  WizardForm.CancelButton.Top := Storage[3] + HeightOffset;
  WizardForm.ComponentsList.Height := Storage[4] + HeightOffset;
  WizardForm.OuterNotebook.Height := Storage[5] + HeightOffset;
  WizardForm.InnerNotebook.Height := Storage[6] + HeightOffset;
  WizardForm.Bevel.Top := Storage[7] + HeightOffset;
  WizardForm.BeveledLabel.Top := Storage[8] + HeightOffset;
  WizardForm.ComponentsDiskSpaceLabel.Top := Storage[9] + HeightOffset;
end;

procedure InitializeWizard;
begin
  CompPageModified := False;
end;

procedure CurPageChanged(CurPageID: Integer);
begin
  if CurpageID = wpSelectComponents then
  begin
    SaveComponentsPage(CompPagePositions);
    LoadComponentsPage(CompPagePositions, ScaleY(200));
    CompPageModified := True;
  end
  else
  if CompPageModified then
  begin
    LoadComponentsPage(CompPagePositions, 0);
    CompPageModified := False;
  end;
end;
