Get a list of running WPF Windows on a WinForm application-CodePudding

I've implemented some new WPF stuff in a old WinForm app project and I used to run it as the following:

    WpfWindow win = new WpfWindow(); // is a subclass of System.Windows.Window
    System.Windows.Forms.Integration.ElementHost.EnableModelessKeyboardInterop(win);
    WindowInteropHelper helper = new WindowInteropHelper(win);
    helper.Owner = this.Handle;

    win.Show();

now the question is, how can I get a list of opened Windows? In a native WPF project I simply do:

var windows = Application.Current.Windows

but I did not find any way in a form project.

CodePudding user response：

Before you show the first Window, for example in startup of your application, create an instance of System.Windows.Application (and forget it).

var app = new System.Windows.Application();

Later, in your WinForms application, you can easily find all WPF windows:

var windows = System.Windows.Application.Current.Windows

Note:

Do this only once, for example in startup of the application. Look at source code of the application class.

It's pretty similar to the way that a WPF app does it:

public partial class App : System.Windows.Application 
{
    ...
    ...
    ...         
    public static void Main() 
    {
        WpfApp1.App app = new WpfApp1.App();
        app.InitializeComponent();
        app.Run();
    }
}
