BlockContext

Struct BlockContext 

pub struct BlockContext<'bfc> { /* private fields */ }
Expand description

Context for each individual Block within a Block Formatting Context

Contains a mutable reference to the BlockFormattingContext + block-specific data

Implementations§

§

impl BlockContext<'_>

pub fn sub_context( &mut self, additional_y_offset: f32, insets: [f32; 2], ) -> BlockContext<'_>

Create a sub-BlockContext for a child block node

pub fn is_bfc_root(&self) -> bool

Returns whether this block is the root block of it’s Block Formatting Context

§

impl BlockContext<'_>

pub fn set_width(&mut self, available_width: f32)

Set the width of the overall Block Formatting Context. This is used to resolve positions that are relative to the right of the context such as right-floated boxes.

Sub-blocks within a Block Formatting Context should use the Self::sub_context method to create a sub-BlockContext with insets instead.

pub fn apply_content_box_inset(&mut self, content_box_x_insets: [f32; 2])

Set the x-axis content-box insets of the BlockContext. These are the difference between the border-box and the content-box of the box (padding + border + scrollbar_gutter).

pub fn has_floats(&self) -> bool

Whether the float context contains any floats

pub fn has_active_floats(&self, min_y: f32) -> bool

Whether the float context contains any floats that extend to or below min_y

pub fn place_floated_box( &mut self, floated_box: Size<f32>, min_y: f32, direction: FloatDirection, clear: Clear, ) -> Point<f32>

Position a floated box with the context

pub fn find_content_slot( &self, min_y: f32, clear: Clear, after: Option<usize>, ) -> ContentSlot

Search a space suitable for laying out non-floated content into

pub fn cleared_threshold(&self, clear: Clear) -> Option<f32>

Get the bottom of lowest relevant float for the specific clear property

pub fn floated_content_height_contribution(&self) -> f32

Returns the height that descendent floats consume
