Struct SidePanel

pub struct SidePanel { /* private fields */ }

A panel that covers the entire left or right side of a Ui or screen.

The order in which you add panels matter! The first panel you add will always be the outermost, and the last you add will always be the innermost.

⚠ Always add any CentralPanel last.

See the module level docs for more details.

egui::SidePanel::left("my_left_panel").show(ctx, |ui| {
   ui.label("Hello World!");
});

Implementations

impl SidePanel

pub fn left(id: impl Into<Id>) -> SidePanel

The id should be globally unique, e.g. Id::new("my_left_panel").

pub fn right(id: impl Into<Id>) -> SidePanel

The id should be globally unique, e.g. Id::new("my_right_panel").

pub fn new(side: Side, id: impl Into<Id>) -> SidePanel

The id should be globally unique, e.g. Id::new("my_panel").

pub fn resizable(self, resizable: bool) -> SidePanel

Can panel be resized by dragging the edge of it?

Default is true.

If you want your panel to be resizable you also need a widget in it that takes up more space as you resize it, such as:

• Wrapping text (Ui::horizontal_wrapped).
• A ScrollArea.
• A Separator.
• A TextEdit.
• …

pub fn show_separator_line(self, show_separator_line: bool) -> SidePanel

Show a separator line, even when not interacting with it?

Default: true.

pub fn default_width(self, default_width: f32) -> SidePanel

The initial wrapping width of the SidePanel.

pub fn min_width(self, min_width: f32) -> SidePanel

Minimum width of the panel.

pub fn max_width(self, max_width: f32) -> SidePanel

Maximum width of the panel.

pub fn width_range(self, width_range: impl Into<Rangef>) -> SidePanel

The allowable width range for the panel.

pub fn exact_width(self, width: f32) -> SidePanel

Enforce this exact width.

pub fn frame(self, frame: Frame) -> SidePanel

Change the background color, margins, etc.

impl SidePanel

pub fn show_inside<R>( self, ui: &mut Ui, add_contents: impl FnOnce(&mut Ui) -> R, ) -> InnerResponse<R>

Show the panel inside a Ui.

pub fn show<R>( self, ctx: &Context, add_contents: impl FnOnce(&mut Ui) -> R, ) -> InnerResponse<R>

Show the panel at the top level.

pub fn show_animated<R>( self, ctx: &Context, is_expanded: bool, add_contents: impl FnOnce(&mut Ui) -> R, ) -> Option<InnerResponse<R>>

Show the panel if is_expanded is true, otherwise don’t show it, but with a nice animation between collapsed and expanded.

pub fn show_animated_inside<R>( self, ui: &mut Ui, is_expanded: bool, add_contents: impl FnOnce(&mut Ui) -> R, ) -> Option<InnerResponse<R>>

Show the panel if is_expanded is true, otherwise don’t show it, but with a nice animation between collapsed and expanded.

pub fn show_animated_between<R>( ctx: &Context, is_expanded: bool, collapsed_panel: SidePanel, expanded_panel: SidePanel, add_contents: impl FnOnce(&mut Ui, f32) -> R, ) -> Option<InnerResponse<R>>

Show either a collapsed or a expanded panel, with a nice animation between.

pub fn show_animated_between_inside<R>( ui: &mut Ui, is_expanded: bool, collapsed_panel: SidePanel, expanded_panel: SidePanel, add_contents: impl FnOnce(&mut Ui, f32) -> R, ) -> InnerResponse<R>

Show either a collapsed or a expanded panel, with a nice animation between.
