Struct qt_widgets::q_graphics_scene::SceneLayer

#[repr(transparent)]
pub struct SceneLayer(_);

This enum describes the rendering layers in a QGraphicsScene. When QGraphicsScene draws the scene contents, it renders each of these layers separately, in order.

C++ enum: QGraphicsScene::SceneLayer.

C++ documentation:

This enum describes the rendering layers in a QGraphicsScene. When QGraphicsScene draws the scene contents, it renders each of these layers separately, in order.

Each layer represents a flag that can be OR'ed together when calling functions such as invalidate() or QGraphicsView::invalidateScene().

This enum was introduced or modified in Qt 4.3.

The SceneLayers type is a typedef for QFlags<SceneLayer>. It stores an OR combination of SceneLayer values.

See also invalidate() and QGraphicsView::invalidateScene().

Methods

impl SceneLayer

pub fn to_int(&self) -> c_int

impl SceneLayer

pub const ItemLayer: SceneLayer

The item layer. QGraphicsScene renders all items are in this layer by calling the virtual function drawItems(). The item layer is drawn after the background layer, but before the foreground layer. (C++ enum variant: ItemLayer = 1)

pub const BackgroundLayer: SceneLayer

The background layer. QGraphicsScene renders the scene's background in this layer by calling the virtual function drawBackground(). The background layer is drawn first of all layers. (C++ enum variant: BackgroundLayer = 2)

pub const ForegroundLayer: SceneLayer

The foreground layer. QGraphicsScene renders the scene's foreground in this layer by calling the virtual function drawForeground(). The foreground layer is drawn last of all layers. (C++ enum variant: ForegroundLayer = 4)

pub const AllLayers: SceneLayer

All layers; this value represents a combination of all three layers. (C++ enum variant: AllLayers = 65535)
