Esempi

Nell'esempio seguente viene illustrato come impostare un gestore eventi per gli Opened eventi Closed e.The following example shows how to set an event handler for the Opened and Closed events.

tooltip.Opened +=
  new RoutedEventHandler(whenToolTipOpens);
tooltip.Closed +=
  new RoutedEventHandler(whenToolTipCloses);
AddHandler tooltip.Opened, AddressOf whenToolTipOpens
AddHandler tooltip.Closed, AddressOf whenToolTipCloses

void whenToolTipOpens(object sender, RoutedEventArgs e)
{
    Ellipse ell = new Ellipse();
    if (sender.GetType().FullName.Equals("System.Windows.Shapes.Ellipse"))
    {
        ell = (Ellipse)sender;
        ell.Fill = Brushes.Blue;
    }
    else if (sender.GetType().FullName.Equals(
                             "System.Windows.Controls.ToolTip"))
    {
        ToolTip t = (ToolTip)sender;
        Popup p = (Popup)t.Parent;
        ell = (Ellipse)p.PlacementTarget;
        ell.Fill = Brushes.Blue;
    }
}

void whenToolTipCloses(object sender, RoutedEventArgs e)
{
    Ellipse ell = new Ellipse();
    if (sender.GetType().FullName.Equals(
                      "System.Windows.Shapes.Ellipse"))
    {
        ell = (Ellipse)sender;
        ell.Fill = Brushes.Gray;
    }
    else if (sender.GetType().FullName.Equals(
                           "System.Windows.Controls.ToolTip"))
    {
        ToolTip t = (ToolTip)sender;
        Popup p = (Popup)t.Parent;
        ell = (Ellipse)p.PlacementTarget;
        ell.Fill = Brushes.Gray;
    }
}


Private Sub whenToolTipOpens(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim ell As New Ellipse()
    If sender.GetType().FullName.Equals("System.Windows.Shapes.Ellipse") Then
        ell = CType(sender, Ellipse)
        ell.Fill = Brushes.Blue
    ElseIf sender.GetType().FullName.Equals("System.Windows.Controls.ToolTip") Then
        Dim t As ToolTip = CType(sender, ToolTip)
        Dim p As Popup = CType(t.Parent, Popup)
        ell = CType(p.PlacementTarget, Ellipse)
        ell.Fill = Brushes.Blue
    End If
End Sub

Private Sub whenToolTipCloses(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim ell As New Ellipse()
    If sender.GetType().FullName.Equals("System.Windows.Shapes.Ellipse") Then
        ell = CType(sender, Ellipse)
        ell.Fill = Brushes.Gray
    ElseIf sender.GetType().FullName.Equals("System.Windows.Controls.ToolTip") Then
        Dim t As ToolTip = CType(sender, ToolTip)
        Dim p As Popup = CType(t.Parent, Popup)
        ell = CType(p.PlacementTarget, Ellipse)
        ell.Fill = Brushes.Gray
    End If
End Sub
