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()。

\ 编辑器窗口，用于检测在激活切换按钮且鼠标位于窗口之上后发生的鼠标移动。

// 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.

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();
    }
