MouseHover / MouseLeave事件在整个窗口中 [英] MouseHover/MouseLeave event on the whole entire window

问题描述

我有Form子类，带有 MouseHover 和 MouseLeave 的处理程序。当指针位于窗口的背景上时，事件工作正常，但是当指针移动到窗口中内的控件时，会导致 MouseLeave event。

I have Form subclass with handlers for MouseHover and MouseLeave. When the pointer is on the background of the window, the events work fine, but when the pointer moves onto a control inside the window, it causes a MouseLeave event.

有没有事件覆盖整个窗口。

Is there anyway to have an event covering the whole window.

推荐答案

当鼠标离开事件被触发时，一个选项是检查当前位置的指针，看看它是否在窗体区域内。我不知道是否有更好的选择。

When the mouse leave event is fired one option is to check for the current position of the pointer and see if it within the form area. I am not sure whether a better option is available.
