need explanation of code piece in WPF DockingDemo2008

[EXAPT Systemtechnik GmbH]

In Window1.xaml.cs I find the following code section. Could someone explain this to me?
private void InitWindowsFormsHost()
{
if( DockingManager.UseInteropCompatibilityMode )
{
WindowsFormsHost host = new WindowsFormsHost();
WinForms.Button btn = new WinForms.Button();
btn.Text = "Winows Forms Button";
host.Child = btn;
FindResults.Content = host;
WindowsFormsHost.EnableWindowsFormsInterop();
}
}

Hi Christoph,

Thanks for your interest in Syncfusion products.

Basically we set UseInteropCompatibilityMode to true when we use WinForms controls in DockingManager of WPF. By the code snippet, we place WinForms's Button inside of the ContentControl(FindResults). WindowsFormsHost.EnableWindowsFormsInterop() funtion enables a System.Windows.Forms.Form to function correctly when it is opened modelessly from WPF
