EditorGUIUtility.CommandEvent

Parameters

Description

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;
            }
        }
    }
}
