Struct WindowOpsImpl 

pub struct WindowOpsImpl<'a> { /* private fields */ }

App-level implementation of teksilo_core::WindowOps handed into every dispatch_event_with_ops call.

Holds &mut WindowManager plus &ActiveEventLoop so open_window can create the winit-level window synchronously before returning. Constructed by TeksiloAppHandler::dispatch_in_window after temporarily removing the dispatching window from WindowManager::windows; the removed tree is borrowed mutably for the handler run.

Implementations

impl<'a> WindowOpsImpl<'a>

pub fn new( wm: &'a mut WindowManager, event_loop: &'a ActiveEventLoop, current_id: TeksiloWindowId, current_handle: Option<RawWindowHandle>, current_window_arc: Option<Arc<Window>>, ) -> Self

Trait Implementations

impl WindowOps for WindowOpsImpl<'_>

fn open_window(&mut self, config: WindowConfig) -> TeksiloWindowId

Open a new window. Creates the winit-level window synchronously inside this call and returns its id, which is immediately valid for any other method on this trait.

fn find_window(&self, string_id: &str) -> Option<TeksiloWindowId>

Look up a window by the stable string id it was opened with (WindowConfig::id). Returns None if no live window carries that id.

fn window_state(&self, id: TeksiloWindowId) -> Option<WindowState>

Read the reactive state for a specific window.

fn windows(&self) -> Vec<WindowState>

Every live window’s state, in creation order.

fn focus_window(&mut self, id: TeksiloWindowId)

Raise a window and give it keyboard focus.

fn request_activation_token( &mut self, id: TeksiloWindowId, cb: Box<dyn FnOnce(Option<String>)>, )

Request an xdg_activation_v1 token for id — to hand to another window or a child process so it can raise itself on Wayland. cb fires once with the token string, or with None where unsupported (everything but Wayland/X11). Default implementation: immediate None.

fn request_activation_token_self(&mut self, cb: Box<dyn FnOnce(Option<String>)>)

Like request_activation_token but for the current dispatching window — the one whose handler is running. Works even mid-dispatch, when that window is temporarily out of the manager’s map, because it uses the captured window handle instead of an id lookup. Use this when a focused widget needs a token to hand to another window or process. Default implementation: immediate None.

fn close_window_by_id(&mut self, id: TeksiloWindowId)

Close a specific window by id. The window is fully torn down before the next event-loop tick.

fn current_parent_handle(&self) -> Option<ParentHandle>

Extract the platform parent handle of the window currently dispatching the event (the one that owns the in-flight EventContext). Used by native-dialog integrations (teksilo_platform::file_dialog) to parent OS dialogs to the originating Teksilo window.

fn set_ime_cursor_area(&mut self, area: Rect)

Report the focused text widget’s caret rectangle (in window-logical pixels) so the platform can position the OS IME candidate window next to the insertion point. Called from text-editing widgets whenever the caret moves. The app applies it to the in-flight window’s set_ime_cursor_area, deduped against the last value.

fn begin_os_drag( &mut self, data: OutboundDragData, image: Option<DragImageData>, ) -> bool

Hand an OS-level drag to the platform when an in-app drag escalates at the window boundary (the pointer left the window carrying an OS-exportable payload). The platform backend (teksilo_platform::external_dnd) starts a native drag session (NSDraggingSource / wl_data_source / OLE IDropSource) using data, optionally drawing image as the drag cursor.

fn cancel_os_drag(&mut self)

Abandon an OS drag started by Self::begin_os_drag (the user pressed Escape).
