主题：有双击列头的事件吗？

那请教一下，如果鼠标移动到表中某一列的列标题时，出现一些提示这列用途的信息要怎么实现叱？

 

Public headCol As Integer = -1
Public myToolTip As New Windows.Forms.ToolTip()
Public Sub MouseLeaveCellHandler(sender As object, e As C1.Win.C1FlexGrid.RowColEventArgs )
headcol = -1
myToolTip.SetToolTip(sender, "")
End Sub

Public Sub MouseEnterCellHandler(sender As object, e As C1.Win.C1FlexGrid.RowColEventArgs )
If e.Row < sender.Rows.Fixed Then
    headcol = e.Col
   
    myToolTip.SetToolTip(sender, "提示")
   
End If
End Sub

Public Sub DoubleClickHandler(sender As object, e As System.EventArgs)
If headcol <> -1 Then
    output.show(sender.Name & " " & Tables(sender.Name).Cols(headcol-1).Name)
End If
End Sub
