Struct Options

pub struct Options {
    pub tessellation_options: TessellationOptions,
    pub screen_reader: bool,
    pub preload_font_glyphs: bool,
    pub warn_on_id_clash: bool,
    /* private fields */
}

Some global options that you can read and write.

Fields

tessellation_options: TessellationOptions

Controls the tessellator.

screen_reader: bool

This is a signal to any backend that we want the crate::PlatformOutput::events read out loud.

The only change to egui is that labels can be focused by pressing tab.

Screen readers is an experimental feature of egui, and not supported on all platforms.

eframe supports it only on web, using the web_screen_reader feature flag, but you should consider using AccessKit instead, which eframe supports.

preload_font_glyphs: bool

If true, the most common glyphs (ASCII) are pre-rendered to the texture atlas.

Only the fonts in Style::text_styles will be pre-cached.

This can lead to fewer texture operations, but may use up the texture atlas quicker if you are changing Style::text_styles, of have a lot of text styles.

warn_on_id_clash: bool

Check reusing of Ids, and show a visual warning on screen when one is found.

By default this is true in debug builds.
