SettingsProvider.OnTitleBarGUI

描述

使用此函数通过 IMGUI 来重载 SettingsProvider 的标题绘制。因此您可以在标题旁边添加自定义 UI（例如工具栏按钮）。AssetSettingsProvider 使用此机制来显示“add to preset”和“help”按钮。

class SimpleIMGUISettingsProvider : SettingsProvider
{
    SerializedObject m_Settings;
    const string k_MyCustomSettingsPath = "Assets/Editor/MyCustomSettings.asset";
    public SimpleIMGUISettingsProvider(string path, SettingsScope scope = SettingsScope.User)
        : base(path, scope) {}

    public override void OnGUI(string searchContext)
    {
        // Use IMGUI to display UI:
        EditorGUILayout.PropertyField(m_Settings.FindProperty("m_Number"), new GUIContent("My Number"));
        EditorGUILayout.PropertyField(m_Settings.FindProperty("m_SomeString"), new GUIContent("Some string"));
        m_Settings.ApplyModifiedPropertiesWithoutUndo();
    }

    public override void OnTitleBarGUI()
    {
        // This button appears right after the Title of the currently selected SettingsProvider:
        if (GUILayout.Button("Help!", EditorStyles.miniButton))
        {
            Debug.Log("You are on your own.");
        }
    }
