[SOLVED] How do I bind a command to a key press in an Avalonia MVVM app built with the Community Toolkit?

How do I bind a command to a key press in an Avalonia MVVM app built with the Community Toolkit?

I am developing a simple desktop MVVM application with Avalonia and the Community Toolkit (the most recent stable versions to the date - Avalonia 11.00.2 and Community Toolkit 8.2.1).

I want it to be keyboard-controlled, having no button controls on the form.

How do I bind a command (a viewmodel method attributed with the Community Toolkit RelayCommandAttribute) to a key press, e.g. F3?

In fact I am interested in both cases: when the view is a Window (the IClassicDesktopStyleApplicationLifetime case) and when it is a UserControl (the ISingleViewApplicationLifetime case) but any single one of these would already be helpful.

Solution

I have found out that the way I was trying to do this was correct, I just misspelled my command name.

Adding the following to the MainWindow.axaml does the job binding MyCommand to the F3 button:

<Window.KeyBindings>
    <KeyBinding Gesture="F3" Command="{Binding MyCommand}" />
</Window.KeyBindings>

This works even though the actual command is defined in a viewmodel of MainView which is a control within the main window (as well as when it is defined in a viewmodel of the window itself i.e. in both cases I have mentioned in the question).
