## Quick Reference

### Register a Callback

if OneWoW_Bags then
    OneWoW_Bags:RegisterItemButtonCallback("MyAddon", MyCallback)
end

function MyCallback(button, bagID, slotID)
    -- Your code here
end
```

### Get Item Information

```lua
local itemLocation = ItemLocation:CreateFromBagAndSlot(bagID, slotID)

if C_Item.DoesItemExist(itemLocation) then
    local itemLink = C_Item.GetItemLink(itemLocation)
    local containerInfo = C_Container.GetContainerItemInfo(bagID, slotID)
    -- Process item
else
    -- Empty slot
end
```

### Create an Overlay

```lua
if not button.MyOverlay then
    button.MyOverlay = CreateFrame("Frame", nil, button)
    button.MyOverlay:SetAllPoints(button)
    button.MyOverlay:SetFrameLevel(button:GetFrameLevel() + 1)
end
```

## Integration Paths

3. Customize based on your needs
4. Reference API docs if stuck

**Total time: 15-20 minutes**

### Path 3: I'm Making a Transmog Addon

1. Copy [Examples/TransmogLootHelper.lua](./Examples/TransmogLootHelper.lua)
2. Update function names to match your addon
3. Reference [ITEM_BUTTON.md](../Docs/ITEM_BUTTON.md#working-with-items) section "Working with Items"

## Common Questions

### How do I get started?

Copy [Examples/Basic.lua](./Examples/Basic.lua) to your addon and follow the comments.

### Where do I find example code?

Check [Examples/](./Examples/) folder. It has four ready-to-use examples for different use cases.

### What API functions are available?

See [ITEM_BUTTON.md](../Docs/ITEM_BUTTON.md#functions) for the complete API reference.

### How do I debug if something doesn't work?

See [ITEM_BUTTON.md - Troubleshooting](../Docs/ITEM_BUTTON.md#troubleshooting) for common issues and solutions.

### Can I add multiple overlays?

Yes! Each addon can register its own callback. Different overlays won't conflict as long as you use unique property names (e.g., `button.MyAddonOverlay` instead of `button.overlay`).

### Is the integration automatic?

Yes! Once you add your integration file to your addon's `.toc` file, it loads and registers automatically when your addon loads.

### What if OneWoW Bags isn't installed?

The integration file checks for `OneWoW_Bags` and only runs if it exists. If OneWoW Bags isn't installed, your addon continues working normally (users just won't see overlays in OneWoW Bags).

### Can I unregister my callback later?

Yes! Call:
```lua
OneWoW_Bags:UnregisterItemButtonCallback("MyAddon")
```

### How often do callbacks fire?

Callbacks fire whenever OneWoW Bags updates item buttons, which is frequently as items are picked up, swapped, and displayed. Keep callbacks lightweight.
