The basics

The details

Resolves

FixesRaspberryPiFoundation/blockly-keyboard-experimentation#499

Proposed Changes

This ensures that non-blocks which hold active focus correctly update LineCursor's internal state.

Reason for Changes

This is outright a correction in how LineCursor has worked up until now, and is now possible after several recent changes (most notably #9004). #9004 updated selection to be more explicitly generic (and based on IFocusableNode) which means LineCursor should also properly support more than just blocks when synchronizing with focus (in place of selection), particularly since lots of non-block things can be focusable.

What's interesting is that this change isn't strictly necessary, even if it is a reasonable correction and improvement in the robustness of LineCursor. Essentially everywhere navigation is handled results in a call to setCurNode which correctly sets the cursor's internal state (with no specific correction from focus since only blocks were checked and we already ensure that selecting a block correctly focuses it).

Test Coverage

It would be nice to add test coverage specifically for the cursor cases, but it seems largely unnecessary since:

  1. The main failure cases are test-specific (as mentioned above).
  2. These flows are better left tested as part of broader accessibility testing (per Add tests for accessibility use cases #8915).

This has been tested with a cursory playthrough of some basic scenarios (block movement, insertion, deletion, copy & paste, context menus, and interacting with fields).

Documentation

No new documentation should be needed here.

Additional Information

This is expected to only affect keyboard navigation plugin behaviors, particularly plugin tests.

It may be worth updating LineCursor to completely reflect current focus state rather than holding an internal variable. This, in turn, may end up simplifying solving issues like #8793 (but not necessarily).

Will look in depth later, but just posted #9033 which almost merges the two, leaving INavigable solely for getClass(); if we remove that, we could just have both the cursor and the focus infrastructure operate on IFocusableNodes, which would be nice.

This ensures that non-blocks which hold active focus correctly update LineCursor's internal state.

Reason for Changes

This is outright a correction in how LineCursor has worked up until now, and is now possible after several recent changes (most notably #9004). #9004 updated selection to be more explicitly generic (and based on IFocusableNode) which means LineCursor should also properly support more than just blocks when synchronizing with focus (in place of selection), particularly since lots of non-block things can be focusable.

What's interesting is that this change isn't strictly necessary, even if it is a reasonable correction and improvement in the robustness of LineCursor. Essentially everywhere navigation is handled results in a call to setCurNode which correctly sets the cursor's internal state (with no specific correction from focus since only blocks were checked and we already ensure that selecting a block correctly focuses it).

Test Coverage

It would be nice to add test coverage specifically for the cursor cases, but it seems largely unnecessary since:

  1. The main failure cases are test-specific (as mentioned above).
  2. These flows are better left tested as part of broader accessibility testing (per Add tests for accessibility use cases #8915).

This has been tested with a cursory playthrough of some basic scenarios (block movement, insertion, deletion, copy & paste, context menus, and interacting with fields).

Documentation

No new documentation should be needed here.

Additional Information

This is expected to only affect keyboard navigation plugin behaviors, particularly plugin tests.

It may be worth updating LineCursor to completely reflect current focus state rather than holding an internal variable. This, in turn, may end up simplifying solving issues like #8793 (but not necessarily).

@gonfunko I'm curious whether you have any thoughts on this PR, as well, since it's largely touching on navigable things (which may also change with your plans to maybe remove INavigable entirely).

Will look in depth later, but just posted #9033 which almost merges the two, leaving INavigable solely for getClass(); if we remove that, we could just have both the cursor and the focus infrastructure operate on IFocusableNodes, which would be nice.
