# Gear Form
This page is about {ref}`Gear Layouts` dedicated `TLazForm` utilities.

This is meant to be used with {ref}`TScriptForm` with
{ref}`TScriptForm.CreateGearTab` and will setup a a `TLazTabSheet` on it with
several controls to configure the {ref}`Gear Layouts`:

## TGearFormHelper
The `TGearFormHelper` type is, as it's name implies a helper type for the
`Gear Form`.

It has a lot of methods and callbacks that are hidden by default and won't be mentioned on
this page because they are internal methods you shouldn't touch.

Do feel free to read the source code though if you so desire.

## GearForm.CreateGearCombobox
```pascal
function TGearFormHelper.CreateGearCombobox(owner: Pointer; caption: TLazLabel = nil): TLazComboBox;
```
This is the only method from {ref}`Gear Form` you might need to use.
This will create a combobox for you whose contents auto-update with changes made
on the `Gear Form`.

## GearForm variable
Global {ref}`TGearFormHelper` variable.
