foldout | 显示的折叠状态。 |
content | 要显示的标签。 |
style | 可选 GUIStyle。 |
menuAction | 在单击图标时发生的操作。 |
menuIcon | 图标的可选 GUIStyle。 |
bool 用户选择的折叠状态。如果为 true,则应渲染子对象。
创建一个左侧带有折叠箭头的标签。
这适用于文件夹之类的结构,其中子对象仅在展开父项时显示。此控件不能嵌套在其他 BeginFoldoutHeaderGroup 中。要使用多个折叠,每个方法都必须以 EndFoldoutHeaderGroup 结尾。
创建可隐藏或显示所选变换的可折叠标题菜单。
// Create a foldable header menu that hides or shows the selected Transform position. // If you have not selected a Transform, the Foldout item stays folded until // you select a Transform.
using UnityEditor; using UnityEngine;
public class FoldoutHeaderUsage : EditorWindow { bool showPosition = true; string status = "Select a GameObject";
[MenuItem("Examples/Foldout Header Usage")] static void CreateWindow() { GetWindow<FoldoutHeaderUsage>(); }
public void OnGUI() { showPosition = EditorGUILayout.BeginFoldoutHeaderGroup(showPosition, status);
if (showPosition) if (Selection.activeTransform) { Selection.activeTransform.position = EditorGUILayout.Vector3Field("Position", Selection.activeTransform.position); status = Selection.activeTransform.name; }
if (!Selection.activeTransform) { status = "Select a GameObject"; showPosition = false; } // End the Foldout Header that we began above. EditorGUILayout.EndFoldoutHeaderGroup(); } }
创建可在单击时将所选对象移到 0,0,0 的菜单项操作。
// Create a foldable header menu that hides or shows the selected Transform position. // If you have not selected a Transform, the Foldout item stays folded until // you select a Transform.
using UnityEditor; using UnityEngine;
public class FoldoutHeaderUsage : EditorWindow { bool showPosition = true; string status = "Select a GameObject";
[MenuItem("Examples/Foldout Header Usage")] static void CreateWindow() { GetWindow<FoldoutHeaderUsage>(); }
public void OnGUI() { showPosition = EditorGUILayout.BeginFoldoutHeaderGroup(showPosition, status, null, ShowHeaderContextMenu);
if (showPosition) if (Selection.activeTransform) { Selection.activeTransform.position = EditorGUILayout.Vector3Field("Position", Selection.activeTransform.position); status = Selection.activeTransform.name; }
if (!Selection.activeTransform) { status = "Select a GameObject"; showPosition = false; } // End the Foldout Header that we began above. EditorGUILayout.EndFoldoutHeaderGroup(); }
void ShowHeaderContextMenu(Rect position) { var menu = new GenericMenu(); menu.AddItem(new GUIContent("Move to (0,0,0)"), false, OnItemClicked); menu.DropDown(position); }
void OnItemClicked() { Undo.RecordObject(Selection.activeTransform, "Moving to center of world"); Selection.activeTransform.position = Vector3.zero; } }
