我试图在几秒钟不活动时隐藏鼠标指针,然后在用户移动鼠标时再次重新显示指针。我已经能够让鼠标指针隐藏并重新显示,但是当我执行grid.Children.Clear()
和grid.Children.Add()
鼠标指针重新出现时(但是在几秒钟之后再次隐藏)不活动)。
我的代码如下:
Private Sub Window1_MouseMoved(ByVal sender As Object, ByVal e As MouseEventArgs) Handles MyBase.MouseMove
'MsgBox("Mouse Has Moved", MsgBoxStyle.Critical, "Mouse Moved")
LastMouseMove = DateTime.Now
If IsHidden Then
Cursor = Cursors.Arrow
IsHidden = False
End If
End Sub
Private Sub MouseHide_Tick(ByVal sender As Object, ByVal e As EventArgs)
Dim elaped As TimeSpan = DateTime.Now - LastMouseMove
If elaped >= TimeoutToHide AndAlso Not IsHidden Then
Cursor = Cursors.None
IsHidden = True
'System.Console.SetCursorPosition(0, 0)
End If
End Sub
Private Sub setupMouseHide()
Try
'Dim timer As New System.Timers.Timer(1000)
Dim dispatcherTimer As DispatcherTimer = New System.Windows.Threading.DispatcherTimer()
AddHandler dispatcherTimer.Tick, AddressOf MouseHide_Tick
dispatcherTimer.Interval = New TimeSpan(0, 0, 3)
dispatcherTimer.Start()
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Critical, "Setup Display Message: error encountered")
End Try
End Sub
我想知道这是一个已知问题还是有更好的方法来实现我想要做的事情?
谢谢,

这可能是一个错误,但布局更改引起鼠标移动事件的情况并不少见。
我想说你最好的选择是检查并存储鼠标移动事件中鼠标的实际坐标。这样你可以忽略错误的鼠标移动事件。
不理想,但我认为它会起作用。
