## TInventoryFormHelper
The `TInventoryFormHelper` type is, as it's name implies a helper type for the
`Inventory 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.

## InventoryForm.CreateGearCombobox
```pascal
function TInventoryFormHelper.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`.

## InventoryForm variable
Global {ref}`TInventoryFormHelper` variable.
