# Bind Widget

```cpp
/* BindWidget meta means the Blueprint will not compile unless there is a child component in the UMG hierarchy that matches the exact name and type or child of type.
* Note: There is a possibility of this being nullptr if not using a blueprint class. */
UPROPERTY(EditAnywhere, BlueprintReadOnly, meta = (BindWidget))
    class UTextBlock* TXT_Tooltip = nullptr;
```

{% hint style="warning" %}
Note: This pointer isn’t assigned until AFTER the widget is made visible (ie, AddToViewport, AddToPlayerScreen, WidgetPointer->AddChild).
{% endhint %}
