Some window managers (on both X11 and Wayland) hide the title-bar close button for Gtk.Dialog windows that have no action buttons. The previous fix (PR #333) added set_decorated(True) which was not sufficient. This adds an explicit Close action button to the dialog so users always have a visible way to dismiss it, regardless of WM behavior. The instant-apply pattern is preserved — settings still apply immediately on change.

Tests for the SettingsDialog.
|
|
|
|
Since SettingsDialog inherits from Gtk.Dialog which is mocked during tests,
|
|
we can't easily test the actual class methods. Instead, we test the core
|
|
logic that the settings dialog is supposed to execute.
|
|
|
|
UX Design Notes tested:
|
|
- Instant-apply pattern: settings apply immediately when changed
|
|
- No action buttons - uses title bar close (GNOME HIG)
