MAUI Popups, floating windows and containers - maui

Question

I need to get a popup window that is not bound to the main window but will allow me to determine where on the screen should it appear.
Requirements:
I need to be able to decide the size, and location of the new window even if it's on another screen. (I'm already detecting all the screens so this is not an issue)
I need to be able to operate / change values on the main window while the new window stays in place and receives commands from the changing values on the first window and displays them (Text for example)
The new window should be able to display text but also it would be nice if it would be able to receive a background photo/video.
Is it at all possible in MAUI?
I know how to do that in Windows Forms but it looks like Windows Forms ls out of date and it soon will not be supported.
Also MAUI seems to have a nicer appearance out of the box. I really like it but I'm not sure if what I need to do is doable at the moment?

Answer 1

Yes, you can use Multi-window support in MAUI as Jason suggested.
You can call an Action to invoke the method in main window, or communicate with the ViewModel of the main page when you want to receive commands from the changing values on the first window and displays them, see Data binding and MVVM - .NET MAUI | Microsoft Learn
Here's the code snippets below for your reference:
private void OnCounterClicked(object sender, EventArgs e)
      {
Window secondWindow = new Window(new NewPage( FirstImage, "First window String to Second", ( string second) =>
            {
                  CounterBtn.Text = second;
})) ;
var displayInfo = DeviceDisplay.Current.MainDisplayInfo;
secondWindow.X = (displayInfo.Width / displayInfo.Density - Window.Width) / 2;
secondWindow.Y = (displayInfo.Height / displayInfo.Density - Window.Height) / 2;
            Application.Current.OpenWindow(secondWindow);
}
public NewPage(Image firstImage, string firstTitle, Action<string> firstTitleAction)
{
InitializeComponent();
SecontTitleLabel.Text = firstTitle;//get the text from first window
firstTitleAction("SecondTitle");
}
