Revit API Hook 之拦截鼠标双击元素事件

阅读本文章前应具有一定编程基础和 Window API 相关知识

第一步，先封装HookBase抽象类，因所有Hook的都具有注册、卸载逻辑，且注册、卸载大同小易。如下：

 public abstract class HookBase : IHook{private static Dictionary<int, IHook> m_Hooks;private IntPtr m_ProcessId;private int m_ThreadId;private HookType m_HookType;private HookProc m_HookProc;protected internal int m_HookId;static HookBase(){m_Hooks = new Dictionary<int, IHook>();}private HookBase(HookType hookType){m_HookType = hookType;m_HookProc = HookProc;}protected HookBase(IntPtr processId, HookType hookType): this(hookType){m_ProcessId = processId;if (m_ProcessId == IntPtr.Zero){m_ProcessId = HookHelper.GetCurrentProcessId();}}protected HookBase(int threadId, HookType hookType): this(hookType){m_ThreadId = threadId;if (m_ThreadId == 0){m_ThreadId = HookHelper.GetCurrentThreadId();}}public void Install(){if (m_ThreadId != 0){m_HookId = HookHelper.SetWindowsHookEx(m_HookType, m_HookProc, IntPtr.Zero, m_ThreadId);}else{if (m_ProcessId == IntPtr.Zero){return;}m_HookId = HookHelper.SetWindowsHookEx(m_HookType, m_HookProc, m_ProcessId, 0);}if (m_HookId == 0){return;}if (!m_Hooks.ContainsKey(m_HookId)){m_Hooks.Add(m_HookId, this);}}public void Uninstall(){if (m_HookId == 0){return;}var flag = HookHelper.UnhookWindowsHookEx(m_HookId);if (flag){if (m_Hooks.Remove(m_HookId)){m_HookId = 0;}}}protected abstract int HookProc(int nCode, IntPtr wParam, IntPtr lParam);

第二步，因鼠标Hook分为线程鼠标Hook以及全局鼠标Hook两种，仅注册方式有点区别。为使用方便，将其封装为事件注册方式。如下

 public abstract class MouseHookBase : HookBase{protected MouseHookBase(IntPtr processId): base(processId, HookType.WH_MOUSE_LL){}protected MouseHookBase(int threadId): base(threadId, HookType.WH_MOUSE){}/// <summary>/// 鼠标双击/// </summary>public event HookHandler<MouseEventArgs> MouseDoubleClick;/// <summary>/// 鼠标移动/// </summary>public event HookHandler<MouseEventArgs> MouseMove;/// <summary>/// 鼠标按下/// </summary>public event HookHandler<MouseEventArgs> MouseDown;/// <summary>/// 鼠标弹起/// </summary>public event HookHandler<MouseEventArgs> MouseUp;protected override int HookProc(int nCode, IntPtr wParam, IntPtr lParam){if (nCode < 0){return HookHelper.CallNextHookEx(m_HookId, nCode, wParam, lParam);}var mouseMsg = (MouseMessage)wParam.ToInt32();var mouseHookStruct = lParam.ToStruct<MOUSEHOOKSTRUCT>();var button = this.GetMouseButtons(mouseMsg);switch (mouseMsg){case MouseMessage.WM_LBUTTONDOWN:case MouseMessage.WM_RBUTTONDOWN:case MouseMessage.WM_MBUTTONDOWN:return this.OnRaiseMouseDown(button, 1, mouseHookStruct.pt.X, mouseHookStruct.pt.Y, mouseHookStruct.mouseData);case MouseMessage.WM_LBUTTONUP:case MouseMessage.WM_MBUTTONUP:case MouseMessage.WM_RBUTTONUP:return this.OnRaiseMouseUp(button, 1, mouseHookStruct.pt.X, mouseHookStruct.pt.Y, mouseHookStruct.mouseData);case MouseMessage.WM_LBUTTONDBLCLK:case MouseMessage.WM_RBUTTONDBLCLK:case MouseMessage.WM_MBUTTONDBLCLK:return this.OnRaiseMouseDoubleClick(button, 2, mouseHookStruct.pt.X, mouseHookStruct.pt.Y, mouseHookStruct.mouseData);case MouseMessage.WM_MOUSEMOVE:return this.OnRaiseMouseMove(MouseButtons.None, 0, mouseHookStruct.pt.X, mouseHookStruct.pt.Y, mouseHookStruct.mouseData);default:return HookHelper.CallNextHookEx(m_HookId, nCode, wParam, lParam);}}private MouseButtons GetMouseButtons(MouseMessage mouseMsg){MouseButtons result = MouseButtons.None;switch (mouseMsg){case MouseMessage.WM_LBUTTONDBLCLK:case MouseMessage.WM_LBUTTONDOWN:case MouseMessage.WM_LBUTTONUP:result = MouseButtons.Left;break;case MouseMessage.WM_MBUTTONDBLCLK:case MouseMessage.WM_MBUTTONDOWN:case MouseMessage.WM_MBUTTONUP:result = MouseButtons.Middle;break;case MouseMessage.WM_RBUTTONDBLCLK:case MouseMessage.WM_RBUTTONDOWN:case MouseMessage.WM_RBUTTONUP:result = MouseButtons.Right;break;}return result;}private int OnRaiseMouseDoubleClick(MouseButtons button, int clicks, int x, int y, int delta){if (this.MouseDoubleClick != null){return this.MouseDoubleClick(this, new MouseEventArgs(button, clicks, x, y, delta));}return 0;}private int OnRaiseMouseDown(MouseButtons button, int clicks, int x, int y, int delta){if (this.MouseDown != null){return this.MouseDown(this, new MouseEventArgs(button, clicks, x, y, delta));}return 0;}private int OnRaiseMouseUp(MouseButtons button, int clicks, int x, int y, int delta){if (this.MouseUp != null){return this.MouseUp(this, new MouseEventArgs(button, clicks, x, y, delta));}return 0;}private int OnRaiseMouseMove(MouseButtons button, int clicks, int x, int y, int delta){if (this.MouseMove != null){return this.MouseMove(this, new MouseEventArgs(button, clicks, x, y, delta));}return 0;}}

第三步，依次实现线程鼠标Hook以及全局鼠标Hook.

    /// <summary>/// 线程鼠标Hook./// </summary>/// <seealso cref="DotNet.Hook.Achieve.MouseHookBase" />public class MouseHook : MouseHookBase{public MouseHook(int threadId = 0): base(threadId){}}/// <summary>/// 全局鼠标钩子/// </summary>/// <seealso cref="DotNet.Hook.Achieve.MouseHookBase" />public class GlobalMouseHook : MouseHookBase{public GlobalMouseHook(IntPtr processId): base(processId){}}

第四步，有了鼠标Hook，我们如果在Revit内使用并且拦截鼠标双击元素事件呢？我们继续封装一个元素监控类，如下：

    /// <summary>/// 元素监控./// </summary>public class ElementMonitor{private static ElementMonitor m_Instance;private MouseHook m_MouseHook;private bool m_IsMonitor;private UIApplication m_UIApplication;private ElementMonitor(UIApplication uiApp){m_Instance = this;m_UIApplication = uiApp;m_MouseHook = new MouseHook();m_MouseHook.Install();m_MouseHook.MouseDoubleClick += OnRaiseMouseDoubleClick;}/// <summary>/// 静态实例，可在入口类判断此实例是否为null，防止重复注册./// </summary>public static ElementMonitor Instance{get{return m_Instance;}}/// <summary>/// 当鼠标双击元素时触发此事件./// </summary>public event HookHandler<DoubleClickElementEventArgs> DoubleClickElement;/// <summary>/// 注册元素监控，并指定是否立即监控./// </summary>public static void Register(UIApplication uiApp, bool immediatelyMonitor = true){if (uiApp == null){throw new ArgumentNullException(nameof(uiApp));}new ElementMonitor(uiApp){m_IsMonitor = immediatelyMonitor};}/// <summary>/// 注册元素监控，并指定是否立即监控./// </summary>public static void Register(UIControlledApplication uiControllApp, bool immediatelyMonitor = true){if (uiControllApp == null){throw new ArgumentNullException(nameof(uiControllApp));}var flag = System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.InvokeMethod;var uiApp = (UIApplication)uiControllApp.GetType().InvokeMember("getUIApplication", flag, Type.DefaultBinder, uiControllApp, null);Register(uiApp, immediatelyMonitor);}/// <summary>/// 返回1，则拦截鼠标消息，返回0则传递给真正消息接收者./// </summary>private int OnRaiseMouseDoubleClick(object sender, System.Windows.Forms.MouseEventArgs e){if (!m_IsMonitor || e.Button != MouseButtons.Left || e.Clicks != 2){return 0;}var uiDoc = m_UIApplication.ActiveUIDocument;if (uiDoc == null){return 0;}var elemIds = uiDoc.Selection.GetElementIds();if (elemIds.Count == 1){var elem = uiDoc.Document.GetElement(elemIds.First());if (elem == null){return 0;}if (this.DoubleClickElement == null){return 0;}return this.DoubleClickElement(this, new DoubleClickElementEventArgs(elem));}return 0;}}

第五步，调用测试，如下

    [Transaction(TransactionMode.Manual)]public class MouseHookTest : IExternalCommand{Result IExternalCommand.Execute(ExternalCommandData commandData, ref string message, ElementSet elements){if (ElementMonitor.Instance == null){ElementMonitor.Register(commandData.Application);}ElementMonitor.Instance.DoubleClickElement += OnRaiseDoubleClickElement;return Result.Succeeded;}private int OnRaiseDoubleClickElement(object sender, DoubleClickElementEventArgs e){if (e.Element == null){return 0;}System.Windows.Forms.MessageBox.Show(string.Format("双击击元素Id： {0}", e.Element.Id));return 1;}}
