OpenPicker()

Detailed Method Reference

Namespace: Canley.Utility.ColourPicker
Class: CanleyColourController

OpenPicker

public void OpenPicker()

• Description: The primary method to activate the Colour Picker UI. Beyond simply showing the panel, this method performs critical state management:
  1. State Snapshot: It captures the current color of the picker (the _startingColor). This allows the CancelSelection method to revert the UI perfectly if the user decides not to proceed.
  2. Theme Synchronization: It triggers ApplyTheme() to ensure all TextMeshPro elements and button colors match your project’s current aesthetic.
  3. Layout Refresh: It calls ForceLayoutRebuild() to ensure the UI components (especially the Swatch Container) calculate their sizes correctly before becoming visible.
• Returns: void
• Example:

using UnityEngine;
using Canley.Utility.ColourPicker;
 
public class MyGameUI : MonoBehaviour 
{
    [SerializeField] private CanleyColourController _picker;
 
    public void OnEditCharacterColor() 
    {
        // Open the picker and prepare for user interaction
        _picker.OpenPicker();
    }
}

TIP

Always use OpenPicker() instead of manually setting the GameObject to active. By using this method, you ensure the user has a “safety net”�the ability to cancel their changes and return to their original color without you having to write additional state-tracking logic.
