Enable/Disable ToolTips for all controls in wpf app

Question

I am writing a WPF application which has a lot of different controls, each with its own ToolTip. Although the ToolTips are useful, some of them are quite long and get in the way.

I want to be able to create a button which will enable and disable all the tooltips on the app when it is clicked. what I've been working on seems like a really long and unnecessary way of going at is. Is there a way to accomplish what I want in a quick manner?

You could try to add an implicit style that sets the Visbility property of all ToolTips to Collapsed for all top-level windows. Something like this:

private bool _isToolTipVisible = true;
private void Button_Click(object sender, RoutedEventArgs e)
{
    Style style = new Style(typeof(ToolTip));
    style.Setters.Add(new Setter(UIElement.VisibilityProperty, Visibility.Collapsed));
    style.Seal();

    foreach (Window window in Application.Current.Windows)
    {
        if (_isToolTipVisible)
        {
            window.Resources.Add(typeof(ToolTip), style); //hide
            _isToolTipVisible = false;
        }
        else
        {
            window.Resources.Remove(typeof(ToolTip)); //show
            _isToolTipVisible = true;
        }
    }
}
