Required Methods

fn ui(&self) -> &Ui

fn ui_mut(&mut self) -> &mut Ui

Provided Methods

fn success_label(&mut self, success_text: &str) -> Response

Shows a success label with a large border.

If you don’t want a border, use crate::ContextExt::success_text.

fn warning_label(&mut self, warning_text: &str) -> Response

Shows a warning label with a large border.

If you don’t want a border, use crate::ContextExt::warning_text.

fn error_with_details_on_hover(&mut self, error_text: &str) -> Response

Shows a small error label with the given text on hover and copies the text to the clipboard on click with a large border.

This has a large border! If you don’t want a border, use crate::ContextExt::error_text.

fn error_label_background_color(&self) -> Color32

fn error_label(&mut self, error_text: &str) -> Response

Shows an error label with the entire error text and copies the text to the clipboard on click.

Use this only if the error message is short, or you have a lot of room. Otherwise, use Self::error_with_details_on_hover.

This has a large border! If you don’t want a border, use crate::ContextExt::error_text.

fn small_icon_button(&mut self, icon: &Icon) -> Response

fn small_icon_button_widget<'a>(&self, icon: &'a Icon) -> Button<'a>

fn medium_icon_toggle_button( &mut self, icon: &Icon, selected: &mut bool ) -> Response

fn large_button_impl( &mut self, icon: &Icon, bg_fill: Option<Color32>, tint: Option<Color32> ) -> Response

fn re_checkbox( &mut self, selected: &mut bool, text: impl Into<WidgetText> ) -> Response

fn checkbox_indeterminate( &mut self, selected: &mut bool, text: impl Into<WidgetText>, indeterminate: bool ) -> Response

fn re_radio_value<Value>( &mut self, current_value: &mut Value, alternative: Value, text: impl Into<WidgetText> ) -> Response

where Value: PartialEq,

fn large_button(&mut self, icon: &Icon) -> Response

fn large_button_selected(&mut self, icon: &Icon, selected: bool) -> Response

fn visibility_toggle_button(&mut self, visible: &mut bool) -> Response

fn full_span_separator(&mut self) -> Response

Create a separator similar to egui::Separator but with the full span behavior.

The span is determined using crate::UiExt::full_span. Contrary to egui::Separator, this separator allocates a single pixel in height, as spacing is typically handled by content when full span highlighting is used.

fn list_item_popup<R>( &self, popup_id: Id, widget_response: &Response, vertical_offset: f32, add_contents: impl FnOnce(&mut Ui) -> R ) -> Option<R>

Popup similar to egui::popup_below_widget but suitable for use with crate::list_item::ListItem.

Note that add_contents is called within a crate::list_item::list_item_scope.

fn panel_content<R>(&mut self, add_contents: impl FnOnce(&mut Ui) -> R) -> R

fn panel_title_bar(&mut self, label: &str, hover_text: Option<&str>)

Static title bar used to separate panels into section.

This title bar is meant to be used in a panel with proper inner margin and clip rectangle set.

Use UiExt::panel_title_bar_with_buttons to display buttons in the title bar.

fn panel_title_bar_with_buttons<R>( &mut self, label: &str, hover_text: Option<&str>, add_right_buttons: impl FnOnce(&mut Ui) -> R ) -> R

Static title bar used to separate panels into section with custom buttons when hovered. h This title bar is meant to be used in a panel with proper inner margin and clip rectangle set.

fn collapsing_header<R>( &mut self, label: &str, default_open: bool, add_body: impl FnOnce(&mut Ui) -> R ) -> CollapsingResponse<R>

Replacement for egui::CollapsingHeader that respect our style.

The layout is fine-tuned to fit well in inspector panels (such as Rerun’s Selection Panel) where the collapsing header should align nicely with checkboxes and other controls.

fn maybe_collapsing_header<R>( &mut self, collapsing: bool, label: &str, default_open: bool, add_body: impl FnOnce(&mut Ui) -> R ) -> CollapsingResponse<R>

Conditionally collapsing header.

Display content under a header that is conditionally collapsible. If collapsing is true, this is equivalent to Self::collapsing_header. If collapsing is false, the content is displayed under a static, non-collapsible header.

fn paint_collapsing_triangle( &self, openness: f32, center: Pos2, visuals: &WidgetVisuals )

Paint a collapsing triangle with rounded corners.

Alternative to egui::collapsing_header::paint_default_icon. Note that the triangle is painted with a fixed size.

fn grid_left_hand_label(&mut self, label: &str) -> Response

Workaround for putting a label into a grid at the top left of its row.

You only need to use this if you expect the right side to have multi-line entries.

fn selection_grid(&self, id: &str) -> Grid

Two-column grid to be used in selection view.

Use this when you expect the right column to have multi-line entries.

fn draw_shadow_line(&self, rect: Rect, direction: Direction)

Draws a shadow into the given rect with the shadow direction given from dark to light

fn list_item(&self) -> ListItem

Convenience function to create a list_item::ListItem.

fn list_item_flat_noninteractive( &mut self, content: impl ListItemContent ) -> Response

Convenience for adding a flat non-interactive list_item::ListItemContent

fn list_item_collapsible_noninteractive_label<R>( &mut self, label: impl Into<WidgetText>, default_open: bool, children_ui: impl FnOnce(&mut Ui) -> R ) -> Option<R>

Convenience to create a non-interactive, collapsible list_item::ListItem with just a label. The children UI is wrapped in a list_item::list_item_scope.

fn section_collapsing_header<'a>( &self, label: impl Into<WidgetText> ) -> SectionCollapsingHeader<'a>

Convenience function to create a crate::SectionCollapsingHeader.

fn selectable_label_with_icon( &mut self, icon: &Icon, text: impl Into<WidgetText>, selected: bool, style: LabelStyle ) -> Response

fn paint_time_cursor( &self, painter: &Painter, response: &Response, x: f32, y: Rangef )

Paints a time cursor for indicating the time on a time axis along x.

fn bullet(&mut self, color: Color32)

Draw a bullet (for text lists).

fn center<R>( &mut self, id_salt: impl Hash, add_contents: impl FnOnce(&mut Ui) -> R ) -> R

Center the content within egui::Ui::max_rect().

The add_contents closure is executed in the context of a vertical layout.

fn toggle_switch(&mut self, height: f32, on: &mut bool) -> Response

Binary toggle switch.

Adapted from egui_demo_lib/src/demo/toggle_switch.rs

fn re_hyperlink( &mut self, text: impl Into<WidgetText>, url: impl ToString ) -> Response

Helper for adding a list-item hyperlink.

fn native_window_buttons_ui(&mut self)

Show some close/maximize/minimize buttons for the native window.

Assumes it is in a right-to-left layout.

Use when crate::CUSTOM_WINDOW_DECORATIONS is set.

fn help_hover_button(&mut self) -> Response

fn markdown_ui(&mut self, markdown: &str)

Show some markdown

fn drop_down_menu( &mut self, id_salt: impl Hash, selected_text: String, content: impl FnOnce(&mut Ui) )

A drop-down menu with a list of options.

Designed for use with list_item content.

Use this instead of using egui::ComboBox directly.

fn full_span_scope<R>( &mut self, span: impl Into<Rangef>, content: impl FnOnce(&mut Ui) -> R ) -> R

Use the provided range as full span for the nested content.

See Self::full_span for details.

fn full_span(&self) -> Rangef

Retrieve the current full-span scope.

By default, this method uses a heuristics to identify which parent Ui’s boundary should be used (e.g. top-level panel, tooltip, etc.). Use Self::full_span_scope to set a specific range as full span.

fn selectable_toggle<R>(&mut self, content: impl FnOnce(&mut Ui) -> R) -> R

Style egui::Ui::selectable_values and friends into a horizontal, toggle-like widget.

Example

let mut flag = false;
ui.selectable_toggle(|ui| {
    ui.selectable_value(&mut flag, false, "Inactive");
    ui.selectable_value(&mut flag, true, "Active");
});
