Visual Basic

' This utility method creates a RolloverItem 
' and adds it to a ToolStrip control.
 Private Function CreateRolloverItem( _
 ByVal owningToolStrip As ToolStrip, _
 ByVal txt As String, _
 ByVal f As Font, _
 ByVal imgKey As String,
 _
 ByVal tir As TextImageRelation, _
 ByVal backImgKey As String)
 As RolloverItem

     Dim item As New RolloverItem()

     item.Alignment = ToolStripItemAlignment.Left
     item.AllowDrop = False
     item.AutoSize = True

     item.BackgroundImage = owningToolStrip.ImageList.Images(backImgKey)
     item.BackgroundImageLayout = ImageLayout.Center
     item.DisplayStyle = ToolStripItemDisplayStyle.ImageAndText
     item.DoubleClickEnabled = True
     item.Enabled = True
     item.Font = f

     ' These assignments are equivalent. Each assigns an
     ' image from the owning toolstrip's image list.
     item.ImageKey = imgKey
     'item.Image = owningToolStrip.ImageList.Images[infoIconKey];
     'item.ImageIndex = owningToolStrip.ImageList.Images.IndexOfKey(infoIconKey);
     item.ImageScaling = ToolStripItemImageScaling.None

     item.Owner = owningToolStrip
     item.Padding = New Padding(2)
     item.Text = txt
     item.TextAlign = ContentAlignment.MiddleLeft
     item.TextDirection = ToolStripTextDirection.Horizontal
     item.TextImageRelation = tir

     Return item
 End Function
