WPF：如何将鼠标光标放在代码中？

Question

我正在无边框窗口上实现系统菜单（恢复，移动，大小...），我希望在选择大小或移动时鼠标光标移动到窗口的中心。理想情况下在VB中，但C＃也很好。

Answer 1

您可以使用SetCursorPos功能，例如：

Declare Function SetCursorPos& Lib "user32" (ByVal p As Point)

'...

dim p as point
p.x = 100
p.y = 200
SetCursorPos p

Answer 2

一些调整似乎有效：

Private Declare Function SetCursorPos Lib "user32" (ByVal x As Int32, ByVal Y As Int32) As Int32

...

With Win

  Dim left As Int32 = CInt(.Left + .Width - CURSOR_OFFSET_MEDIUM)
  Dim top As Int32 = CInt(.Top + .Height / 2)

  SetCursorPos(left, top)

End With
