Editing Eto Form unexposed properties with WPF

Hello all,

We are currently developing a panel and we are looking to create a rather ambitious UI with Eto.

I am wondering if it is at all possible to override the unexposed properties using Eto.Wpf to adjust the various styling.


However, the below codes doesn’t produce any result.

   Styles.Add<Eto.Wpf.Forms.Controls.GroupBoxHandler>("secondaryBox", h => { 
                h.Control.Background = System.Windows.Media.Brushes.Black;
                h.Control.BorderThickness = new System.Windows.Thickness(5);
                h.Control.BorderBrush = System.Windows.Media.Brushes.Red;
