Struct egui::containers::Frame

pub struct Frame {
    pub inner_margin: Margin,
    pub outer_margin: Margin,
    pub rounding: Rounding,
    pub shadow: Shadow,
    pub fill: Color32,
    pub stroke: Stroke,
}

Add a background, frame and/or margin to a rectangular background of a Ui.

egui::Frame::none()
    .fill(egui::Color32::RED)
    .show(ui, |ui| {
        ui.label("Label with red background");
    });

Dynamic color

If you want to change the color of the frame based on the response of the widget, you needs to break it up into multiple steps:

let mut frame = egui::Frame::default().inner_margin(4.0).begin(ui);
{
    let response = frame.content_ui.label("Inside the frame");
    if response.hovered() {
        frame.frame.fill = egui::Color32::RED;
    }
}
frame.end(ui); // Will "close" the frame.

You can also respond to the hovering of the frame itself:

let mut frame = egui::Frame::default().inner_margin(4.0).begin(ui);
{
    frame.content_ui.label("Inside the frame");
    frame.content_ui.label("This too");
}
let response = frame.allocate_space(ui);
if response.hovered() {
    frame.frame.fill = egui::Color32::RED;
}
frame.paint(ui);

Note that you cannot change the margins after calling begin.

Fields

inner_margin: Margin

Margin within the painted frame.

outer_margin: Margin

Margin outside the painted frame.

rounding: Rounding

shadow: Shadow

fill: Color32

stroke: Stroke

Implementations

impl Frame

pub fn none() -> Self

pub fn group(style: &Style) -> Self

For when you want to group a few widgets together within a frame.

pub fn side_top_panel(style: &Style) -> Self

pub fn central_panel(style: &Style) -> Self

pub fn window(style: &Style) -> Self

pub fn menu(style: &Style) -> Self

pub fn popup(style: &Style) -> Self

pub fn canvas(style: &Style) -> Self

A canvas to draw on.

In bright mode this will be very bright, and in dark mode this will be very dark.

pub fn dark_canvas(style: &Style) -> Self

A dark canvas to draw on.

impl Frame

pub fn fill(self, fill: Color32) -> Self

pub fn stroke(self, stroke: impl Into<Stroke>) -> Self

pub fn rounding(self, rounding: impl Into<Rounding>) -> Self

pub fn inner_margin(self, inner_margin: impl Into<Margin>) -> Self

Margin within the painted frame.

pub fn outer_margin(self, outer_margin: impl Into<Margin>) -> Self

Margin outside the painted frame.

pub fn shadow(self, shadow: Shadow) -> Self

pub fn multiply_with_opacity(self, opacity: f32) -> Self

impl Frame

pub fn total_margin(&self) -> Margin

inner margin plus outer margin.

impl Frame

pub fn begin(self, ui: &mut Ui) -> Prepared

Begin a dynamically colored frame.

This is a more advanced API. Usually you want to use Self::show instead.

See docs for Frame for an example.

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

Show the given ui surrounded by this frame.

pub fn paint(&self, outer_rect: Rect) -> Shape

Paint this frame as a shape.

The margin is ignored.

Trait Implementations

impl Clone for Frame

fn clone(&self) -> Frame

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Frame

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Frame

fn default() -> Frame

Returns the “default value” for a type.

impl PartialEq for Frame

fn eq(&self, other: &Frame) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Frame

impl StructuralPartialEq for Frame
