public static Event CommandEvent (string commandName);

参数

commandName 要发送的命令。

描述

创建可以发送到另一个窗口的事件。

// Sends a paste event to an EditorWindow, as if Paste
// was selected from the Edit menu.

using UnityEngine; using UnityEditor;

public class CommandEventExample : EditorWindow { [MenuItem("Examples/CommandEvent example")] static void commandEventExample() { CommandEventExample window = EditorWindow.GetWindowWithRect<CommandEventExample>(new Rect(0, 0, 150, 40)); window.Show(); }

void OnGUI() { if (GUILayout.Button("Paste")) { Event e = EditorGUIUtility.CommandEvent("Paste"); EditorWindow ew = EditorWindow.GetWindow<CommandEventTest>(true); ew.SendEvent(e); } } }

下面的脚本会接收从上述 CommandEventExample 发送的 Paste 消息。

using UnityEngine;
using UnityEditor;

public class CommandEventTest : EditorWindow { private int eventCount = 0;

[MenuItem("Examples/Example that receives a paste event")] static void test() { CommandEventTest window = EditorWindow.GetWindowWithRect<CommandEventTest>(new Rect(0, 0, 100, 40)); window.Show(); }

void OnGUI() { EditorGUI.LabelField(new Rect(10, 10, 90, 30), "Paste: " + eventCount.ToString());

if (Event.current.type == EventType.ExecuteCommand) { Event e = Event.current; if (e.commandName == "Paste") { eventCount = eventCount + 1; } } } }
