Question

Today I got some new restrictions on my WPF user interface that should eliminate the permanent visibility of the MenuBar.

I thought of imitating the user interface of Windows Live Messenger. That application displays the MenuBar only if the ALT-key is pressed. And hides it again when the focus on the MenuBar is lost.

Currently I don’t have a clue how to build such a thing in WPF… is something like this possible?

Thanks in advance.

You can write a key down event on main window..

KeyDown="Window_KeyDown"

and in the code behind file..

 private void Window_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Key == Key.LeftAlt || e.Key == Key.RightAlt)
            {
                myMenu.Visibility = Visibility.Visible;
            }
        }

if you want to achive this with MVVM or using bindings… you can use input key bindings

 <Window.InputBindings>
        <KeyBinding Key="LeftAlt" Command="{Binding ShowMenuCommand}"/>
        <KeyBinding Key="RightAlt" Command="{Binding ShowMenuCommand}"/>
    </Window.InputBindings>
