Everything a presenter may use to draw one control.

New fields may be added in minor releases; read the fields you need.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

control: ShellControl

Which control to draw.

hovered: bool

The pointer is over the control (or hover is simulated in a preview).

pressed: bool

The primary button is held down on the control.

focused: bool

Keyboard focus is visible on the control (or simulated in a preview). The shell already paints a focus ring; use this only for extra treatment.

window_active: bool

The window is active.

appearance: WindowAppearance

Light or dark appearance used for the frame.

high_contrast: bool

High contrast is in effect. Presenters should switch to high-contrast artwork; colors already holds the shell’s high-contrast tokens.

colors: ShellColors

The frame’s resolved colors for this appearance and activation.

focus_color: u32

The focus-ring color the shell uses (0xRRGGBB).

scale: f32

Logical text/target scale (0.5–4), independent of device DPI.

target_size: Pixels

Side of the square clickable target. Presenter content is centered in it and clipped to it; draw the icon smaller to keep a comfortable target.

preview: bool

Drawn in an inert crate::ClientFramePreview, not a real window.
