Struct re_viewer::external::re_ui::list_item::LayoutInfo

pub struct LayoutInfo {
    pub(crate) left_x: f32,
    pub(crate) left_column_width: Option<f32>,
    pub(crate) reserve_action_button_space: bool,
    scope_id: Id,
    pub(crate) property_content_max_width: Option<f32>,
}

Layout information prepared by list_item_scope to be used by super::ListItemContent.

This structure has two purposes:

• Provide read-only layout information to be used when rendering the list item.
• Provide an API to register needs (such as left column width). These needs are then accumulated and used to set up the next frame’s layout information.

super::ListItemContent implementations have access to this structure via super::ContentContext.

Fields

left_x: f32

left_column_width: Option<f32>

reserve_action_button_space: bool

scope_id: Id

property_content_max_width: Option<f32>

Implementations

impl LayoutInfo

pub fn register_desired_left_column_width( &self, ctx: &Context, desired_width: f32 )

Register the desired width of the left column.

All super::ListItemContent implementation that attempt to align on the two-column system should call this function once in their super::ListItemContent::ui method.

pub fn reserve_action_button_space(&self, ctx: &Context, reserve: bool)

Indicate whether right-aligned space should be reserved for the action button.
