The contents of a SplitScroll. The contents of a SplitScroll.

Required Methods

fn left_top_ui(&mut self, ui: &mut Ui)

fn right_top_ui(&mut self, ui: &mut Ui, scroll_offset: Vec2)

fn left_bottom_ui(&mut self, ui: &mut Ui, scroll_offset: Vec2)

fn right_bottom_ui(&mut self, ui: &mut Ui, scroll_offset: Vec2)

Provided Methods

fn paint_overlays(&mut self, _ui: &mut Ui)

Paints overlays (like separator lines). Called inside the ScrollArea viewport closure (clipped to bottom-right) so that scrollbars paint over it. Also called outside (clipped to left) to paint over sticky areas.

fn update_col_widths(&mut self, _ui: &mut Ui)

Updates state like auto-sized column widths and drag interaction. Called after all UI quadrants and paint_overlays have been rendered, ensuring max_column_widths is fully populated and visual lines match the current frame’s layout.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
