Implementations§

Source §

impl FlowLayout

Source

pub fn new() -> Self

Source

pub fn add_table( &mut self, registry: &FontRegistry, params: &TableLayoutParams, available_width: f32, )

Add a table to the flow at the current y position.

Source

pub fn add_frame( &mut self, registry: &FontRegistry, params: &FrameLayoutParams, available_width: f32, )

Add a frame to the flow.

Inline: placed in normal flow, advances content_height.
FloatLeft: placed at current y, x=0. Does not advance content_height (surrounding content wraps around it).
FloatRight: placed at current y, x=available_width - frame_width.
Absolute: placed at (margin_left, margin_top) from document origin. Does not affect flow at all.

Source

pub fn clear(&mut self)

Clear all layout state. Call before rebuilding from a new FlowSnapshot.

Source

pub fn add_block( &mut self, registry: &FontRegistry, params: &BlockLayoutParams, available_width: f32, )

Add a single block to the flow at the current y position.

Source

pub fn layout_blocks( &mut self, registry: &FontRegistry, block_params: Vec<BlockLayoutParams>, available_width: f32, )

Lay out a sequence of blocks vertically.

Source

pub fn relayout_block( &mut self, registry: &FontRegistry, params: &BlockLayoutParams, available_width: f32, )

Update a single block’s layout and shift subsequent blocks if the position or height changed.

If the block’s top margin changed, its y position is recomputed using margin collapsing with the previous block. Subsequent items are shifted by the resulting delta.
