Expand description

A panel that covers the entire top or bottom 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::TopBottomPanel::top("my_panel").show(ctx, |ui| {
   ui.label("Hello World!");
});

Implementations§

source§

impl TopBottomPanel

source

pub fn top(id: impl Into<Id>) -> Self

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

source

pub fn bottom(id: impl Into<Id>) -> Self

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

source

pub fn new(side: TopBottomSide, id: impl Into<Id>) -> Self

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

source

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

Can panel be resized by dragging the edge of it?

Default is false.

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:

source

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

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

Default: true.

source

pub fn default_height(self, default_height: f32) -> Self

The initial height of the TopBottomPanel. Defaults to style::Spacing::interact_size.y.

source

pub fn min_height(self, min_height: f32) -> Self

Minimum height of the panel.

source

pub fn max_height(self, max_height: f32) -> Self

Maximum height of the panel.

source

pub fn height_range(self, height_range: impl Into<Rangef>) -> Self

The allowable height range for the panel.

source

pub fn exact_height(self, height: f32) -> Self

Enforce this exact height.

source

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

Change the background color, margins, etc.

source§

impl TopBottomPanel

source

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

Show the panel inside a Ui.

source

fn show_inside_dyn<'c, R>( self, ui: &mut Ui, add_contents: Box<dyn FnOnce(&mut Ui) -> R + 'c> ) -> InnerResponse<R>

Show the panel inside a Ui.

source

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

Show the panel at the top level.

source

fn show_dyn<'c, R>( self, ctx: &Context, add_contents: Box<dyn FnOnce(&mut Ui) -> R + 'c> ) -> InnerResponse<R>

Show the panel at the top level.

source

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.

source

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.

source

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

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

source

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

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