Update home page when language changes

[Jack251970]

Changes

• When search is empty and Home Page feature is enabled, if the language is changed, the home page will not be updated by its translation until next non-empty query. So we should check if home page is shown and update the translations

Test

• Enable Home Page and change language, the search window results will be updated

[Copilot]

Pull Request Overview

Ensure the home page translations refresh immediately when the application language changes without requiring a new search query.

• Added a conditional check in the language-change handler to trigger a home-page refresh when showing the home page and the query is empty.
• Calls _viewModel.QueryResults() to re-render translations on language switch.

Comments suppressed due to low confidence (1)

Flow.Launcher/MainWindow.xaml.cs:287

• There are no existing tests covering this new refresh logic. Consider adding a unit or integration test that simulates a language change with an empty query to verify the home page translations update as expected.

                        if (_settings.ShowHomePage && _viewModel.QueryResultsSelected() && string.IsNullOrEmpty(_viewModel.QueryText))

📝 Walkthrough

Walkthrough

A conditional block was added to the _settings.PropertyChanged event handler for the Language property in MainWindow.xaml.cs. When the language changes and certain UI conditions are met, the view model's QueryResults() method is called to refresh the query results display.

Flow.Launcher/MainWindow.xaml.cs (1)

287-290: LGTM! Implementation follows existing patterns and addresses the issue correctly.

This change properly addresses the PR objective by refreshing the home page translations when the language changes. The implementation:

1. Uses the same conditional logic as the existing ShowHomePage/ShowHistoryResultsForHomePage handlers (lines 315-318)
2. Appropriately checks all necessary conditions before triggering the refresh
3. Follows the established pattern of calling _viewModel.QueryResults() to update the display

The addition of the _settings.ShowHomePage condition is a good optimization that ensures the refresh only occurs when the home page feature is actually enabled.
