ChatTab

Individual tab button representing a single chat channel. Manages visual selection state (color and font size) and fires a click event consumed by ChatTabs to drive channel switching.

Definition

Namespace: Paragon.Townskeep Assembly: Townskeep.dll

public class ChatTab : ParagonUIBehaviour

Inheritance: SerializedMonoBehaviour → ParagonBehaviour → ParagonUIBehaviour → ChatTab

Remarks

Each ChatTab corresponds to one ChatChannel. The tab is initialized with a channel reference, which sets the button label text and binds the click handler. When clicked, the tab fires OnClicked — which ChatTabs listens to in order to trigger SelectTab().

Visual State

The tab has two visual states controlled by text color and font size:

• Selected — Uses selectedColor and selectedFontSize (configured via [SerializeField])

• Unselected — Reverts to the default color and font size captured in Awake()

State changes are applied by ChatTabs.SelectTab(), which calls Unselect() on the previous tab and Select() on the new one.

Cleanup

On OnDestroy(), the tab nulls out the OnClicked delegate and removes its button listener to prevent stale references.

Events

OnClicked

Fired when the tab's button is clicked. Passes the clicked ChatTab instance.

public Action<ChatTab> OnClicked;

This is a public Action<ChatTab> field, not a C# event. It can be reassigned (not just subscribed to) from external code. ChatTabs subscribes via += during CreateTabs().

Methods

Initialize

Binds the tab to a chat channel, sets the label text, and registers the button click listener.

public void Initialize(ChatChannel channel)

Parameter	Type	Description
channel	ChatChannel	The chat channel to bind to

Select

Applies the selected visual state (color and font size).

public void Select()

Unselect

Reverts to the default visual state (color and font size captured in Awake()).

public void Unselect()

Common Pitfalls

Default color/size captured in Awake() The defaultColor and defaultFontSize are read from the TextMeshProUGUI component in Awake(). If the text component's initial values differ from the intended "unselected" state (e.g., due to prefab overrides), the unselected appearance will be wrong.

OnClicked is a field, not an event Because OnClicked is a public Action<ChatTab> field (not event), it can be overwritten with = instead of +=. Be careful not to replace existing subscribers.
