public bool SendEvent(Event e);

Description

Sends an Event to a window.

The SendEvent public function passes a selected Event to a chosen visible window. The Event can be found in the EventType list.

In the following scripts SendEventExample looks up the ReceiveEventExample window. A Paste event is then sent over when the button is pressed.

// Send an event to another editor window. The second
// window needs to be visible to receive the event.

using UnityEngine;
using UnityEditor;
using UnityEngine.UIElements;

public class SendEventExample : EditorWindow
{
    [MenuItem("Examples/Send Event")]
    static void Init()
    {
        SendEventExample window =
            EditorWindow.GetWindow<SendEventExample>(true, "Send Event Window");
        window.Show();
    }

    void CreateGUI()
    {
        var buttonSendEvent = new Button();
        buttonSendEvent.text = "Send Event";
        buttonSendEvent.clicked += () =>
        {
            EditorWindow win = GetWindow<ReceiveEventExample>();
            if (win)
                using (var commandEvent = ExecuteCommandEvent.GetPooled(EditorGUIUtility.CommandEvent("Paste")))
                {
                    win.rootVisualElement.SendEvent(commandEvent);
                }
        };
        rootVisualElement.Add(buttonSendEvent);
