Winforms：首先在主窗体上拦截鼠标事件，而不是在控件上

问题描述

肯定有一种方便的方法：

There is certainly a convenient way to do this :

我已经在主窗体上实现了关于鼠标拖动行为的移动窗口。 >并且我希望MouseClick / Move事件被表单拦截，而不是被其中的控件拦截。

I have implemented a "Move Window" on mouse drag behavior on my main form,
and I would like the MouseClick/Move event to be intercepted by the form, not by controls that are in it.

我想找到一个等效项/副本鼠标事件的 KeyPreview属性

I would like to find an Equivalent to/replicate the "KeyPreview" property for Mouse Events

此外，我还要避免在12个控件的鼠标事件中分别将鼠标事件重定向到Main Form方法12次（这是到目前为止，我已经找到了丑陋的解决方法）

Besides I want to avoid Redirecting the Mouse Event to the Main Form Method 12 times in 12 Controls' Mouse events individually (which is the ugly workaround I have Found so far)

有什么想法吗？

推荐答案

订阅所有控件MouseMove事件（考虑对嵌套控件进行递归操作）

Subscribe to all controls MouseMove events (consider do it recursively for nested controls)

foreach (Control control in Controls)
    control.MouseMove += RedirectMouseMove;

并在此事件处理程序中举起MouseMove

And raise MouseMove inside this event handler

private void RedirectMouseMove(object sender, MouseEventArgs e)
{
    Control control = (Control)sender;
    Point screenPoint = control.PointToScreen(new Point(e.X, e.Y));
    Point formPoint = PointToClient(screenPoint);
    MouseEventArgs args = new MouseEventArgs(e.Button, e.Clicks, 
        formPoint.X, formPoint.Y, e.Delta);
    OnMouseMove(args);
}

请记住，控件会接收具有本地控件坐标的MouseEvent。因此，您需要将其转换为表单坐标。
嵌套控件可能有缺点，但我留给您使用（例如，调用Parent.PointToClient）

Keep in mind that controls receive MouseEvents with local coordinates of control. So you need to convert it to form coordinates.There are could be drawbacks with nested controls, but I leave it to you (e.g. call Parent.PointToClient)

UPDATE ：您仍然可以处理控制事件-只需再订阅一次事件即可。

UPDATE: You are still will be able to handle events of control - just subscribe to event one more time.
