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 how mouse movement events
// get caught in the Editor window

class WantsMouseMoveEx extends EditorWindow {
    @MenuItem("Example/wantsMouseMove example")
    static function InitWindow() {
        var window : WantsMouseMoveEx = GetWindowWithRect(WantsMouseMoveEx, Rect(0, 0, 300, 300));
    }

    function 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 ();
    }
