WPF主窗口外不会触发鼠标移动 [英] Mouse Move not trigger outside WPF Main Window

问题描述

我想获得鼠标相对于屏幕坐标的位置.我正在使用以下代码来做到这一点.

I want to get mouse position relative to screen coordinates. I am using the following code to do that.

window.PointToScreen(Mouse.GetPosition(window));

它正在按预期方式工作.但是我的MouseMove事件没有在MainWindow外部触发.也就是说，如果我将鼠标移到桌面上并恢复了窗口，就可以了.

It is working as expected. But my MouseMove event not firing outside the MainWindow. That is if I move my mouse over desktop with my window restored.

任何想法都值得赞赏.

推荐答案

使用CaptureMouse()方法.

Use the CaptureMouse() method.

对于上面的示例，您可以添加:

For your example above, you could add:

window.CaptureMouse();

在MouseDown事件处理程序内部的代码后面.

in your code-behind inside the MouseDown event handler.

然后您需要致电:

window.ReleaseMouseCapture();

位于MouseUp事件处理程序内部代码的后面.

in your code-behind inside the MouseUp event handler.
