Struct imgui::ListClipper

pub struct ListClipper { /* private fields */ }

Used to render only the visible items when displaying a long list of items in a scrollable area.

For example, you can have a huge list of checkboxes. Without the clipper you have to call ui.checkbox(...) for every one, even if 99% of of them are not visible in the current frame. Using the ListClipper, you can only call ui.checkbox(...) for the currently visible items.

Note the efficiency of list clipper relies on the height of each item being cheaply calculated. The current rust bindings only works with a fixed height for all items.

Implementations

pub const fn items_height(self, items_height: f32) -> Self
