Modules

• camera_config
  Configuration for cameras related to UI.
• debug
• draw_ui_graph
• measurement
• node
• node_bundles
  This module contains basic node bundles used to build UIs

  This module contains the basic building blocks of Bevy’s UI

Structs

• BackgroundColor
  The background color of the node
• BorderColor
  The border color of the UI node.
• CalculatedClip
  The calculated clip of the node
• ContentSize
  A node with a ContentSize component is a node where its size is based on its content.
• DefaultCameraView
• DrawUiNode
• ExtractedUiNode
• ExtractedUiNodes
• FixedMeasure
  A FixedMeasure is a Measure that ignores all constraints and always returns the same size.
• GridPlacement
  Represents the position of a grid item in a single axis.
• GridTrack
  A GridTrack is a Row or Column of a CSS Grid. This struct specifies what size the track should be. See below for the different “track sizing functions” you can specify.
• LayoutContext
• Node
  Describes the size of a UI node
• NodeQuery
  Main query for ui_focus_system
• NodeQueryItem
  Automatically generated WorldQuery item type for NodeQuery, returned when iterating over query results.
• NodeQueryReadOnly
  Automatically generated WorldQuery type for a read-only variant of NodeQuery.
• NodeQueryReadOnlyItem
  Automatically generated WorldQuery item type for NodeQueryReadOnly, returned when iterating over query results.
• Overflow
  Whether to show or hide overflowing items
• RelativeCursorPosition
  A component storing the position of the mouse relative to the node, (0., 0.) being the top-left corner and (1., 1.) being the bottom-right If the mouse is not over the node, the value will go beyond the range of (0., 0.) to (1., 1.) A None value means that the cursor position is unknown.
• RepeatedGridTrack
  Represents a possibly repeated GridTrack.
• SetUiTextureBindGroup
• SetUiViewBindGroup
• Style
  Describes the style of a UI container node
• TransparentUi
• UiBatch
• UiImage
  The 2D texture displayed for this UI node
• UiImageBindGroups
• UiMeta
• UiPassNode
• UiPipeline
• UiPipelineKey
• UiPlugin
  The basic plugin for Bevy UI
• UiRect
  A type which is commonly used to define margins, paddings and borders.
• UiScale
  The current scale of the UI.
• UiStack
  The current UI stack, which contains all UI nodes ordered by their depth (back-to-front).
• UiSurface
• UiTextureAtlasImage
  The atlas sprite to be used in a UI Texture Atlas Node

Enums

• AlignContent
  Defines how each line is aligned within the flexbox.
• AlignItems
  How items are aligned according to the cross axis
• AlignSelf
  How this item is aligned according to the cross axis. Overrides AlignItems.
• AvailableSpace
  The amount of space available to a node in a given axis https://www.w3.org/TR/css-sizing-3/#available
• Direction
  Defines the text direction
• Display
  Whether to use a Flexbox layout model.
• FlexDirection
  Defines how flexbox items are ordered within a flexbox
• FlexWrap
  Defines if flexbox items appear on a single line or on multiple lines
• FocusPolicy
  Describes whether the node should block interactions with lower nodes
• GridAutoFlow
  Controls whether grid items are placed row-wise or column-wise. And whether the sparse or dense packing algorithm is used.
• GridPlacementError
  Errors that occur when setting contraints for a GridPlacement
• GridTrackRepetition
  How many times to repeat a repeated grid track
• Interaction
  Describes what type of input interaction has occurred for a UI node.
• JustifyContent
  Defines how items are aligned according to the main axis
• JustifyItems
  How items are aligned according to the main axis
• JustifySelf
  How this item is aligned according to the main axis. Overrides JustifyItems.
• LayoutError
• MaxTrackSizingFunction
• MinTrackSizingFunction
• OverflowAxis
  Whether to show or hide overflowing items
• PositionType
  The strategy used to position this node
• RenderUiSystem
• UiSystem
  The label enum labeling the types of systems in the Bevy UI
• Val
  Represents the possible value types for layout properties.
• ValArithmeticError
• ZIndex
  Indicates that this Node entity’s front-to-back ordering is not controlled solely by its location in the UI hierarchy. A node with a higher z-index will appear on top of other nodes with a lower z-index.

Constants

• UI_SHADER_HANDLE

Traits

• Measure
  A Measure is used to compute the size of a ui node when the size of that node is based on its content.

Functions

• extract_default_ui_camera_view
• extract_text_uinodes
• extract_uinode_borders
• extract_uinodes
• prepare_uinodes
• queue_uinodes
• ui_focus_system
  The system that sets Interaction for all UI elements based on the mouse cursor activity
• ui_layout_system
  Updates the UI’s layout tree, computes the new layout geometry and then updates the sizes and transforms of all the UI nodes.
