State: closed
Merged: Yes

Summary of the Pull Request

This PR lays the foundation for a new Actions page in the Settings UI as designed in #6900. The Actions page now leverages the ActionMap to display all of the key bindings and allow the user to modify the associated key chord or delete the key binding entirely.

Detailed Description of the Pull Request / Additional comments

Settings Model Changes

  • Command::Copy() now copies the ActionAndArgs
  • ActionMap::RebindKeys() handles changing the key chord of a key binding. If a conflict occurs, the conflicting key chord is overwritten.
  • ActionMap::DeleteKeyBinding() "deletes" a key binding by binding "unbound" to the given key chord.
  • ActionMap::KeyBindings() presents another view (similar to NameMap) of the ActionMap. It specifically presents a map of key chords to commands. It is generated similar to how NameMap is generated.

Editor Changes

  • Actions.xaml is mainly split into two parts:
    • ListView (as before) holds the list of key bindings. We could explore the idea of an items repeater, but the ListView seems to provide some niceties with regards to navigating the list via the key board (though none are selectable).
    • DataTemplate is used to represent each key binding inside the ListView. This is tricky because it is bound to a KeyBindingViewModel which must provide all context necessary to modify the UI and the settings model. We cannot use names to target UI elements inside this template, so we must make the view model smart and force updates to the UI via changes in the view model.
  • KeyBindingViewModel is a view model object that controls the UI and the settings model.

There are a number of TODOs in Actions.cpp will be long-term follow-ups and would be nice to have. This includes...

  • a binary search by name on Actions::KeyBindingList
  • presenting an error when the provided key chord is invalid.
