Expand description

Controls the visual style (colors etc) of egui.

You can change the visuals of a Ui with Ui::visuals_mut and of everything with crate::Context::set_visuals.

If you want to change fonts, use crate::Context::set_fonts instead.

Fields§

§dark_mode: bool

If true, the visuals are overall dark with light text. If false, the visuals are overall light with dark text.

NOTE: setting this does very little by itself, this is more to provide a convenient summary of the rest of the settings.

§override_text_color: Option<Color32>

Override default text color for all text.

This is great for setting the color of text for any widget.

If text_color is None (default), then the text color will be the same as the foreground stroke color (WidgetVisuals::fg_stroke) and will depend on whether or not the widget is being interacted with.

In the future we may instead modulate the text_color based on whether or not it is interacted with so that visuals.text_color is always used, but its alpha may be different based on whether or not it is disabled, non-interactive, hovered etc.

§widgets: Widgets

Visual styles of widgets

§selection: Selection§hyperlink_color: Color32

The color used for Hyperlink,

§faint_bg_color: Color32

Something just barely different from the background color. Used for crate::Grid::striped.

§extreme_bg_color: Color32

Very dark or light color (for corresponding theme). Used as the background of text edits, scroll bars and others things that needs to look different from other interactive stuff.

§code_bg_color: Color32

Background color behind code-styled monospaced labels.

§warn_fg_color: Color32

A good color for warning text (e.g. orange).

§error_fg_color: Color32

A good color for error text (e.g. red).

§window_rounding: Rounding§window_shadow: Shadow§window_fill: Color32§window_stroke: Stroke§window_highlight_topmost: bool

Highlight the topmost window.

§menu_rounding: Rounding§panel_fill: Color32

Panel background color

§popup_shadow: Shadow§resize_corner_size: f32§text_cursor: Stroke

The color and width of the text cursor

§text_cursor_preview: bool

show where the text cursor would be if you clicked

§clip_rect_margin: f32

Allow child widgets to be just on the border and still have a stroke with some thickness

§button_frame: bool

Show a background behind buttons.

§collapsing_header_frame: bool

Show a background behind collapsing headers.

§indent_has_left_vline: bool

Draw a vertical lien left of indented region, in e.g. crate::CollapsingHeader.

§striped: bool

Whether or not Grids and Tables should be striped by default (have alternating rows differently colored).

§slider_trailing_fill: bool

Show trailing color behind the circle of a Slider. Default is OFF.

Enabling this will affect ALL sliders, and can be enabled/disabled per slider with Slider::trailing_fill.

§handle_shape: HandleShape

Shape of the handle for sliders and similar widgets.

Changing this will affect ALL sliders, and can be enabled/disabled per slider with Slider::handle_shape.

§interact_cursor: Option<CursorIcon>

Should the cursor change when the user hovers over an interactive/clickable item?

This is consistent with a lot of browser-based applications (vscode, github all turn your cursor into CursorIcon::PointingHand when a button is hovered) but it is inconsistent with native UI toolkits.

§image_loading_spinners: bool

Show a spinner when loading an image.

§numeric_color_space: NumericColorSpace

How to display numeric color values.
