[RESOLVED] Sliding panel problem

[ovi_gm]

Hello everybody,

I am trying to make a sliding menu using a panel. I set up a form a new panel with size: 181,107, location 180,-95 and the following code:

Private Sub Panel1_MouseEnter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Panel1.MouseEnter
For i = -95 To 0
Panel1.Location = New Point(180, i)
Threading.Thread.Sleep(1)
Next
End Sub

Private Sub Panel1_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Panel1.MouseLeave
For i = 0 To 95
Panel1.Location = New Point(180, -i)
Threading.Thread.Sleep(1)
Next
End Sub

It works fine until I add a control to the panel. If I add any control and the mouse gets over that control it doesn't work any more and it goes up and down. I assume that when mouse enters the controls then the mouse leave of the panel is activated.

Any idea to make it work?

thx

try this:

Private Sub Panel1_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Panel1.MouseLeave
    Dim p As Point = Panel1.PointToClient(Cursor.Position)
    If Not Panel1.Region.IsVisible(p) Then
        For i = 0 To 95
            Panel1.Location = New Point(180, -i)
            Threading.Thread.Sleep(1)
        Next
    End If
End Sub

ok. as my code in post #2 didn't work (it was copied + pasted from a similar project i wrote, + untested), i had another look + came up with this:

Public Class Form1

    Dim ignore As Boolean = False

    Private Sub Panel1_MouseEnter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Panel1.MouseEnter
        If Not ignore Then
            For i = -95 To 0
                Panel1.Location = New Point(180, i)
                Threading.Thread.Sleep(1)
            Next
        End If
    End Sub

    Private Sub Panel1_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Panel1.MouseLeave
        Dim p As Point = Me.PointToClient(Cursor.Position)
        If Not Panel1.Bounds.Contains(p) Then
            ignore = False
            For i = 0 To 95
                Panel1.Location = New Point(180, -i)
                Threading.Thread.Sleep(1)
            Next
        Else
            ignore = True
        End If
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Panel1.Location = New Point(180, -95)
    End Sub

End Class
