Question

我试图显示放置在列表框上的按钮（类似于acrobat reader工具箱）：当用户在ListBox中移动鼠标时，按钮出现，并且当用户离开ListBox区域时它们必须隐藏。问题是：当我将鼠标移到列表框上时，按钮出现但当我尝试点击它时，程序会将此移动检测为ListBox_MouseLeave并隐藏按钮！...这就是逻辑（鼠标现在是在按钮上）但是......

Private Sub ListBox3_MouseHover(sender As Object, e As MouseEventArgs) Handles ListBox3.MouseHover
    Button6.Visible = True
End Sub

Private Sub ListBox3_MouseLeave(sender As Object, e As EventArgs) Handles ListBox3.MouseLeave
    Button6.Visible = False
End Sub

如何避免使用mouse_leave指令并让按钮可见？

Answer 1

将隐藏代码移至表格鼠标悬停。

Private Sub Form4_MouseHover(sender As Object, e As EventArgs) Handles Me.MouseHover
        Button1.Visible = False
    End Sub

    Private Sub ListBox1_MouseEnter(sender As Object, e As EventArgs) Handles ListBox1.MouseEnter
        Button1.Visible = True
    End Sub

避免使用mouseHover和mouseLeave将按钮放在同一个列表框中
