使用例

Visual Basic

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinTabs
Imports Infragistics.Win.UltraWinTabbedMdi

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    Dim statusText As String = String.Empty
    Dim pt As Point = Control.MousePosition

    ' The 'TabGroupFromPoint' method takes screen coordinates
    ' so we can pass the coordinates from Control.MousePosition
    ' or Cursor.Position without converting them to client 
    ' coordinates.
    Dim tabGroup As MdiTabGroup = Me.ultraTabbedMdiManager1.TabGroupFromPoint(pt)

    ' if the mouse is not over an area managed by an MdiTabGroup,
    ' the method will return null
    If Not tabGroup Is Nothing Then
        ' if we're over a tab group, we may be over an MdiTab
        ' so use the TabFromPoint with the same screen 
        ' coordinates
        Dim tab As MdiTab = Me.ultraTabbedMdiManager1.TabFromPoint(pt)

        If Not tab Is Nothing Then
            ' if we were over a tab, display the actual
            ' text and tooltip it would display as well
            ' as some info about the tab group
            statusText = String.Format("Tab - ToolTip = {0}, Text = {1}, TabGroup = '{2}'", tab.ToolTipResolved, tab.TextResolved, tabGroup)
        Else
            ' otherwise, just use the tab group
            statusText = String.Format("TabGroup = '{0}'", tabGroup)
        End If
    End If

    If Me.StatusBar1.Text <> statusText Then
        Me.StatusBar1.Text = statusText
