Walkthrough

The notation controller adds selection queries and a check for whether a selection can become a system. Command-state rules use these queries to update layout command states when the selection changes. The properties panel model now tracks enabled states for six system and page commands, and the System and Page sections pass those states to their controls.

Merge Risk: Low · up to 8f417

Page-movement buttons can appear enabled for frame selections but do nothing. This is a bounded usability issue; the change is mergeable with owner awareness or a follow-up correction.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 15 functions across 6 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Disable page-movement buttons when the selection has no systems.

When a VBoxBase is selected, the Page tab is shown, but MOVE_SYSTEM_TO_PREV_PAGE_COMMAND falls through to CommandState(true, false) in NotationCommandsState::doCommandState(). Both page-movement buttons therefore remain enabled. Their handlers then return without performing an operation because startMeas->system() and endMeas->system() are null.
