Fields

parent: WlSurface

The parent surface.

state: WindowState

The latest window state.

wm_capabilities: WindowManagerCapabilities

The wm capabilities.

resizable: bool

Whether the frame is resizable.

dirty: bool

Whether the frame is waiting for redraw.

mouse_location: Location

The location of the mouse.

mouse_coords: (i32, i32)

The location of the mouse.

render_data: Option<FrameRenderData>

This should happen in reaction to scale or resize changes.

scale_factor: f64

The active scale factor of the frame.

queue_handle: QueueHandle<State>

The frame queue handle.

pool: SlotPool

The memory pool to use for drawing.

subcompositor: Arc<SubcompositorState>

The subcompositor.

buttons: [Option<UIButton>; 3]

Buttons state.
