Struct StyledPanelFrame 

pub struct StyledPanelFrame { /* private fields */ }

Styled panel frame builder

Creates consistent outer (gap) and inner (content) frames for panels. Handles selective corner rounding patterns where panels meet.

Example

// Method 1: Show both frames with content
egui::CentralPanel::default().show(ui, |ui| {
    StyledPanelFrame::left(ui).show(ui, |ui| {
        ui.label("Panel content");
    });
});

// Method 2: Get frames separately (for a side panel)
let frame = StyledPanelFrame::left(ui);
egui::Panel::left("left")
    .frame(frame.outer_frame())
    .show(ui, |ui| {
        frame.inner_frame().show(ui, |ui| {
            ui.label("Panel content");
        });
    });

Implementations

impl StyledPanelFrame

pub fn left(ui: &Ui) -> Self

Create a left panel frame (drawing toolbar)

Rounded: top-right corner only

pub fn right_widget_bar(ui: &Ui) -> Self

Create a right widget bar frame (icon tabs)

Rounded: top-left corner only

pub fn right_content(ui: &Ui) -> Self

Create a right content panel frame (alerts, object tree, etc.)

Rounded: top-left corner only

pub fn top(ui: &Ui) -> Self

Create a top panel frame (toolbar)

No rounding - spans full width

pub fn bottom(ui: &Ui) -> Self

Create a bottom panel frame (timeline)

No rounding

pub fn chart(ui: &Ui, chart_bg: Color32) -> Self

Create a central chart area frame

Rounded: top-left and top-right corners

pub fn gap_color(self, color: Color32) -> Self

Override the gap color

pub fn panel_bg(self, color: Color32) -> Self

Override the panel background color

pub fn outer_frame(&self) -> Frame

Get the outer frame (gap color with margins)

Panel layout: gaps are created by panel margins

• Top toolbar: bottom margin (gap below toolbar)
• Side panels: horizontal margins only (NO top margin)
• Chart: no margins (gaps from surrounding panels)

pub fn inner_frame(&self) -> Frame

Get the inner frame (panel bg with selective rounding)

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

Show both outer and inner frames with content

This is a convenience method that nests the frames correctly.
