EditorWindow.wantsMouseMove

描述

检查是否已在此编辑器窗口的 GUI 中收到 MouseMove 事件。

如果设置为 true，则每当鼠标移动到窗口之上时，该窗口都会收到一次 OnGUI 调用。

注意：此函数不会自动触发 Repaint()。


Editor Window that detects mouse moves when the toggle button is activated and the mouse is over the window.

// Editor Script that shows the mouse movement events
// captured.  With "Receive Movement" set to true the position of the
// mouse over the window will be reported.
// "Mouse Position" shows where the mouse is outside of the window.

using UnityEditor;
using UnityEngine;
using System.Collections;

public class Example : EditorWindow
{
    [MenuItem("Example/Mouse Move Example")]
    static void InitWindow()
    {
        Example window = (Example)GetWindowWithRect(typeof(Example), new Rect(0, 0, 300, 100));
        window.Show();
    }

    void OnGUI()
    {
        wantsMouseMove = EditorGUILayout.Toggle("Receive Movement: ", wantsMouseMove);
        EditorGUILayout.LabelField("Mouse Position: ", Event.current.mousePosition.ToString());

        // Repaint the window as wantsMouseMove doesnt trigger a repaint automatically
        if (Event.current.type == EventType.MouseMove)
            Repaint();
    }
