Struct egui::Memory

pub struct Memory {
    pub all_collpasing_are_open: bool,
    pub all_menues_are_open: bool,
    pub all_windows_are_open: bool,
    // some fields omitted
}

The data that Egui persists between frames.

This includes window positions and sizes, how far the user has scrolled in a ScrollArea etc.

If you want this to persist when closing your app you should serialize Memory and store it.

Fields

all_collpasing_are_open: bool

Useful for debugging, benchmarking etc.

all_menues_are_open: bool

Useful for debugging, benchmarking etc.

all_windows_are_open: bool

Useful for debugging, benchmarking etc.

Implementations

impl Memory

pub fn layer_at(
    &self,
    pos: Pos2,
    resize_interact_radius_side: f32
) -> Option<Layer>

pub fn has_kb_focus(&self, id: Id) -> bool

pub fn request_kb_focus(&mut self, id: Id)

pub fn surrender_kb_focus(&mut self, id: Id)

pub fn reset_areas(&mut self)

Forget window positions, sizes etc. Can be used to auto-layout windows.

impl Memory

pub fn is_popup_open(&mut self, popup_id: Id) -> bool

pub fn open_popup(&mut self, popup_id: Id)

pub fn close_popup(&mut self)

pub fn toggle_popup(&mut self, popup_id: Id)
