VisualBasic2010においてMouseDown、DragDropを用いてPanelを移動させるコードを書きました。 Panel4へPanel1,Panel2,Panel3を移動させるというものです。 例） Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Shown Panel4.AllowDrop = True End Sub Private Sub Panel1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseDown Panel1.DoDragDrop(Panel1, DragDropEffects.Move) End Sub Private Sub Panel2_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Panel2.MouseDown Panel2.DoDragDrop(Panel2, DragDropEffects.Move) End Sub Private Sub Panel3_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Panel3.MouseDown Panel3.DoDragDrop(Panel3, DragDropEffects.Move) End Sub Private Sub Panel4_DragDrop(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles Panel4.DragDrop Dim srsPnl As Panel = e.Data.GetData(GetType(Panel)) Dim dstPnl As New Panel dstPnl.Size = srsPnl.Size dstPnl.Location = Panel4.PointToClient(CursorPosition) 'New Point(e.X, e.Y) dstPnl.BackColor = srsPnl.BackColor AddHandler dstPnl.MouseDown, AddressOf dstPnl_MouseDown AddHandler dstPnl.MouseMove, AddressOf dstPnl_MouseMove Panel4.Controls.Add(dstPnl) End Sub Private Sub Panel4_DragEnter(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles Panel4.DragEnter If e.Data.GetDataPresent(GetType(Panel)) Then e.Effect = DragDropEffects.Move End If End Sub Private previousPos As Point Private Sub dstPnl_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseDown previousPos = CursorPosition() End Sub Private Sub dstPnl_MouseMove(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) If e.Button = Windows.Forms.MouseButtons.Left Then Dim nowPos As Point = CursorPosition() DirectCast(sender, Panel).Left += nowPos.X - previousPos.X DirectCast(sender, Panel).Top += nowPos.Y - previousPos.Y Console.WriteLine(nowPos.X & "-" & previousPos.X) previousPos = nowPos End If End Sub Function CursorPosition() As Point Return New Point(CInt(Cursor.Position.X / 10) * 10, CInt(Cursor.Position.Y / 10) * 10) End Function このようにした場合、初めに移動させたものが最前にきてしまいます。(画像参照） 私はPanel1(黒）を最前に持っていきたいと考えています。 もしお時間等ありましたら、お力添えをいただけると嬉しく思います。 どうかよろしくお願いします。
