| Parameter | Description |
|---|---|
| key | The key of the existing GUIContent. |
| text | The text associated with the GUIContent.text. |
| tooltip | The tooltip to display when the cursor hovers over the icon. |
| icon | The icon to associate with the GUIContent.image. |
| iconName | The name of the icon. |
Gets the GUIContent from the Unity built-in resources with the given key or creates a GUIContent for a GUI element.
The text and the tooltip are localized and loaded with an icon.
Typically, the icon from `Assets/Editor Default Resources/Icons` is fetched using the icon name. Only the name of the icon, without the .png extension is needed.
Unity translates these with the Editor's own translations.
Note: On the CoreCLR scripting backend the group Unity picks is not reliable, because the JIT compiler can inline the caller and change which assembly Unity sees. Where the group matters, call L10n.Tr with an explicit group name and build the content from what it returns.
