Trait Implementations

impl PlatformTitleBarHost for X11Host

fn reserved_leading_inset(&self) -> Size

Logical-pixel area on the leading edge that the widget must leave blank because the OS draws there. macOS reserves space for the traffic lights; Windows / Wayland return Size::ZERO.

fn reserved_trailing_inset(&self) -> Size

Logical-pixel area on the trailing edge reserved by the OS. Currently always Size::ZERO; reserved for future use.

fn renders_custom_controls(&self) -> bool

Whether the widget should render its own minimize / maximize / close buttons. true on Windows and Wayland; false on macOS where the OS draws the traffic lights.

fn needs_custom_resize_handles(&self) -> bool

Whether the application should install a WindowFrame-style overlay with invisible edge / corner resize strips. true on Windows and Wayland where the client draws the entire frame; false on macOS where the native NSWindow frame still services edge resize.

fn begin_drag(&self) -> Result<(), PlatformError>

Begin an interactive window move. Called on left-press inside a drag region. The OS takes over until the user releases the button.

fn begin_resize(&self, edge: ResizeEdge) -> Result<(), PlatformError>

Begin an interactive resize from the given edge. Called on left-press inside a resize border widget.

fn show_window_menu(&self, _at: Point) -> Result<(), PlatformError>

Show the system window menu at the given client-area position. Wayland only; other platforms return Ok(()) and do nothing.

fn has_window_menu(&self) -> bool

Whether the platform can show a system window menu at all.

fn update_hit_regions(&self, _regions: &HitRegions)

Publish the current rectangles of the title bar’s interactive sub-regions. The widget tree publishes them in logical pixels; backends that need physical pixels (Windows) convert internally. Wayland and macOS ignore the payload.

fn title_bar_widget_id(&self, _target: ControlTarget) -> Option<WidgetId>

Resolve a control-button target back to the WidgetId of the ControlButton that the widget tree last reported for it. Used by the Windows backend’s synthetic-tap forwarding when WM_NCLBUTTONUP fires on HTMINBUTTON/HTMAXBUTTON/HTCLOSE — the OS owns the click area, so the proc looks up the matching widget id and the app routes a synthetic tap into it.

fn set_button_hover(&self, _target: ControlTarget, _entered: bool)

Inject a synthetic hover entered/leave event for the given control button. Used by the Windows backend’s WM_NCMOUSEMOVE / WM_NCMOUSELEAVE path: the OS handles non-client hover, so widget-side hover events never fire over button rects.

fn register_hover_signal(&self, _target: ControlTarget, _signal: Signal<bool>)

Register the per-button hover signal that the host writes when the OS reports a non-client hover for the matching target. Called by WindowControls at build time for each of the three buttons.
