用户尝试触摸过去的屏幕时如何关闭WPF对话框窗口

Question

Please look at image,

It has two windows, red one opens after green one.

How could I close red windows when user touch green screen ?

Also I have using

protected override void OnDeactivated(EventArgs e)
{
    base.OnDeactivated(e);
    Close();
}

But this works only when user open another application

here is my green window code, that opens red window

MainWindow_OnLoaded(object sender, RoutedEventArgs e)
        {
           Window1 w=new Window1();
            w.ShowDialog();
        }

Answer 1

I cannot give you a direct answer since I do not do WPF programming, but an approach I use on IOS is to have one big form, the outer part is transparent and it actually contains one huge button, which is also transparent, only the Window1 is visible. On the button press event close window1.

But I am pretty sure you should have a way to detect click events on the green part and then close the window1. Maybe add some event listener to some component you place on the green part.

See this answer: how to close a WPF Dialog Window when the user clicks outside it

Here is a answer I copied:

public partial class MainWindow : Window
{
public MainWindow()
{
    InitializeComponent();
}

protected override void OnDeactivated(EventArgs e)
{
    base.OnDeactivated(e);
    Close();
}

}
